Agile Benefits: Five Essential Reasons to Try Agile
Although there many other benefits of agile, and although those provide us with other reasons to try agile, the five essential benefits of agile are:
Rapid Learning - disciplined application of the scientific method to explore the best ways to deliver valuable results.
Early Return on Investment - opportunity to use the results of work starting with the work delivered at the end of the first iteration.
Satisfied Stakeholders - engagement in the process in a way that allows meaningful contributions from all stakeholders.
Increased Control - mechanisms to track/measure and therefore steer the direction that work is going so that it meets goals.
Responsiveness to Change - processes, tools, roles and principles that allow a team and an organization to embrace change rather than reject, control or suffer from change.
These reasons are sufficient and apply to operations work, project work and open-ended research work, whenever humans are involved. The above links take you to more detailed descriptions of each of these benefits.
What are some of the other benefits of agile?

Agile Benefits: Responding to Change
The fact that agile methods increase return on investment, accelerate learning, increase stakeholder satisfaction, and enable better control of work are all an interesting result of this final benefit: responding to change.
Responding to Change
The whole idea of "agile", and one of the primary reasons for the choice of this word is the final item of the Agile Manifesto: "Responding to Change". It is clear that this is one of the distinguishing features of agile as compared to a more traditional waterfall or phase-based approach to working. Not so obvious is that this is also true about agile compared to a more chaotic or ad-hoc way of working.
Agile and Waterfall - Change "Control"
In most waterfall or phase-based approaches to working, change control is a technique used to evaluate change requests and then accept or reject them. The practical consequence of this is that "control" often becomes a euphemism for "prevent at almost any price", and we end up with results that satisfy no-one because life changes.
There are, of course, some changes that are accepted even in a change control environment. These changes tend to be the ones that have both a powerful sponsor and a "wealthy" sponsor. The next problem with change control relates to the fact that change becomes very expensive in a phase-based process. It usually means going back to the "beginning" and re-examining the other requirements, the analysis, the design/architecture, the development/construction, the testing and the impact is necessarily large for all but the most trivial changes.
Agile methods turn this on it's head. By allowing (nay, building in!) change every iteration, every cycle, the team and the organization start to get good at accommodating change. The value of this effect cannot be over-estimated; getting good at doing change is a natural consequence of accepting change all the time in a structured manner, and in fact, leads to all the other four benefits: increased learning, increased ROI, increased stakeholder satisfaction, and increased control. The cost of change stabilizes over time instead of increasing exponentially!
Agile and Chaos - The Illusion of Changability
Unfortunately, I am not aware of any studies that target chaotic (non-process) environments to see what kind of results they have in delivering results. (If anyone is aware of such studies, please let me know in the comments!) That said, I think almost everyone has had some experience in environments where the winds of change were so severe and fickle, and the structures to support working with change were non-existent, that chaos reigned. These environments are almost completely negative: things don't get done in a timely manner nor with an acceptable level of quality.
Often the reason for this lack of structure is about flexibility, needing to work in an environment which is also extremely chaotic. Sometimes its worse though: management or stakeholders are the cause of chaos without understanding the consequences of their actions.
Agile methods put a sufficient structure in place to build some discipline, and still remain adaptable. This sufficient structure is often built by gradual application of various agile practices until there is "just enough". This process does require dedication and will, but because it is gradual, it is often much easier than trying to suddenly put in place a full-scale disciplined process.
As these practices are implemented, the team and organization gradually become better and better at accommodating change.

Agile Benefits: Early Return on Investment
We wouldn't do agile if we didn't think it was better in some way. More and more, I am seeing the adoption of agile methods being driven by business management (rather then engineering). There is a clear reason for this: agile methods offer the possibility of early return on investment compared to other methods of working. This benefit is only one of five essential benefits of agile, but it is one of the most practical and easiest to measure. Therefore it is important to clearly understand how agile methods can deliver this benefit... and how they can fail to do so!
Early Return on Investment
The basic process structure of agile methods consists of the short cycles (iterations, Sprints) of delivery of valuable results. The key word there (aside from "short") is "Valuable". Now in software, "valuable" is relatively easy to define. One definition that works nicely is "Running Tested Features". In other industries or types of work, valuable is defined in some other way.
An agile process delivers valuable results every single iteration. This provides the basis of early return on investment. The organization can then take those results and start to realize their benefits immediately after the very first iteration... ideally... (which we will come back to in a moment).
Here's a graphical contrast between a traditional waterfall approach versus an agile approach that maps value delivered vs. time.
The waterfall project delivers all its value at the end - the red spike. An agile project starts delivering value very early on, increases to a maximum rate of value delivery and then gradually tapers off. The reason for the shape is simple: at the start of the project there is often a fair amount of uncertainty, and some dead-ends are pursued before getting to the really valuable work, and then as that work is completed, the team starts working on lower and lower priority features.
The early delivery of value has an additional benefit. By delivering value early, the time value of that investment is increased. Revenue or cost savings can be realized sooner and therefore more funds are feed up for other investment.
Sounds great, what's the catch?
Agile Pitfall: Not Getting Done
This benefit being realized rests completely on the assumption that the work delivered at the end of each iteration is actually valuable. If for some reason it's not, then this benefit falls apart completely. Most organizations when starting with agile, cannot realize this value immediately because their teams do not deliver completed valuable results. Rather, most organizations are set up so that a team delivers an intermediate result which is useless on its own. Realizing this benefit of agile methods often requires substantial, strenuous, disciplined change in the way that people work, teams are set up, bureaucracy functions, and management supports it all. Perfecting agile is sometimes a lengthy process. Fortunately, the other benefits of agile do not depend so heavily on this assumption.

Four Methods of Perfecting Agile
Most organizations start doing agile (or Scrum or lean or ...) imperfectly. Someone introduces a few practices or a manager gets a team some training, or a person starts using agile terminology. And things might improve, particularly with the use of iterations. One of the core ideas of agile methods is to have frequent delivery of valuable results. In fact, this core idea can be used to drive the improvement of an agile process. How? Here are four methods of perfecting agile by expanding the definition of done.
Perfecting Agile
Let's suppose you already understand the benefits of agile. With these benefits in mind, you would like to improve the organization's ability to deliver working, valuable results at the end of every iteration so that you can get better at realizing those benefits. The primary way to do this is by expanding the definition of done. You can imagine this like so:
On a regular basis, the team/organization find ways to bring work done in either the preparation stage or the close stage into every iteration of the agile portion of the project. By moving the work from these "bookend" stages into the iterations, you reduce the amount of time spent in those stages and simultaneously create a more complete delivery every iteration. The "definition of done" is now expanded to contain the results or value delivered by the work that was taken out of the startup and shutdown stages of the project. By expanding the definition of done, each iteration delivers a more "complete" increment of value, and there is less work done before or after iterations in order to plan or deliver. This gradual process allows the team to get better at doing agile.
There are four methods for transferring work from the start and end of a project into the iterations of a project.
Expand the Agile Team's Skill Set
In some ways, this is the simplest and most common approach to expanding the definition of done in the agile portion of a project. By training, coaching, mentoring, re-assigning or hiring, a team's capacity to do work is expanded and used to expand the definition of done. As a simple example, a software developer might learn to use an automated unit testing framework and therefore expand the definition of done to include some amount of unit test coverage of delivered code. In general, training, coaching and mentoring existing team members should be preferred over adding people to the team since the addition disrupts the team's development and can increase communication overhead among team members.
Expand the Agile Team's Authority
Sometimes, a team is not able to do part of the preparation work or close up work because they are not authorized to do so. This may be a policy, a unspoken assumption or a bureaucratic procedure. By giving the team (or some person on the team) the authority to do this work, the team can find ways to do it every iteration instead of having to work through another non-team individual. Again, a simple example here is a situation where a technical person is given permission to talk directly to an end user in order to reduce the need for up-front requirements gathering and analysis and reduce the need for end-of-project user acceptance testing. The obvious challenge to do this is the question of trust (or lack thereof).
Automate an Existing Manual Process
Automation is often given far less than its due consideration. This is primarily be cause automating a process is an investment of work in and of itself. Fortunately, it is often easy to measure the ROI or savings involved with automation. In many agile environments, heavy automation is critical and a huge enabler for very short iterations. Automated testing, automated translation, automated build processes, are all common areas of improvement. Agile teams should always be looking for opportunities to automate their own work. In this way, the automation work itself is transformed from a separate project to a responsibility of the team.
Remove Wasteful Processes
There are some parts of the project preparation work and the project close up work that are pure waste! There is no independent value to these activities, nor is there indirect value to them. An excellent example of this sort of thing is an approval process that _always_ grants approval ("rubber stamping"). One insurance organization I worked with as they were converting to an agile approach discovered that their "second stage" approvals always allowed proposed projects to proceed. Since they often incurred a 4-6 week delay for this approval process, it became obvious that they should "get rid of it". Now, what they actually did is made it so that it became a parallel review process rather than a gated approval process; this was so that the true purpose of the activity could still be met: to help stakeholders understand the projects that were being worked upon. Here, there is no need to take this approval process and somehow work it into every iteration. An agile approach tends to increase the visibility of the work anyway, so it may be discovered later on that the review process can also be done away with.
Agile is often implemented in a limited fashion when it is first adopted by most teams and organizations. The four methods of expanding the definition of done can help a team or organization get better at doing agile and therefore reap more of the benefits of agile. These methods are simple: expand the agile team's capacity, their authority, have them automate manual processes and remove wasteful activities from the process.

Strategic Plan
Okay, this is only marginally related to agile, but I thought it was interesting nevertheless: How to Write a Detailed Strategic Plan. The main connection to Agile Work, is that you need to have a clear performance goal in mind towards which you are working. This may be a great way to clarify your thoughts about such a goal.

The Freedom of Limited Capacity
Something that I would have thought impossible has happened. By understanding how incredibly limited my capacity to do work is, I am getting a greater and greater sense of freedom and contentment.
My "experiement" to run my business using Agile Work practices is starting to bear some fruit. The trouble is, that so far, that fruit is simple better knowledge of my extremely limited capacity to get things done during a single week-long iteration. I can do 3 or 4 items from my Work Queue which works out to about 15 or 20 tasks. This seems ridiculous to me! Surely one hard-working guy can get more than that done!
But I can't. I'm getting to the end of my fourth iteration and it's the same thing again!
I know some of the reasons for this: interruptions, unexpected work, unremembered work, and my general nature of being easily distracted by shiny things!
In some ways this has been quite frustrating. I have a huge queue of work I want to get done for my business. But the other side of the coin, the one that looks different than I expected, is that knowing just how limited my capacity is... is liberating! I don't feel nearly as stressed as I did four weeks ago. I have the courage to commit at an appropriate level. I can start to believe my plans. I can see - realistically - just how much I need help to achieve my goals. I can see how soon I will be able to do cost/benefit analysis on hiring vs. doing the work myself (can't do that yet). I can even start to believe that I might be able to reach my original goal of reducing my working hours from 80+/week to 50 or less... as long as I make sure that my Work Queue is properly prioritized with that goal in mind.
I have worked with a number of teams that have gotten to this point of certainty about their capacity. I've seen this happen in others... and now I recognize it for what it is: relief. One team I worked with after only two iterations had a very clear idea of their capacity, and you could feel the comfort level of everyone with this new agile thing skyrocket. Another team I worked with got a clear sense of its capacity after only three iterations. This team settled in and then started to work to increase their capacity and did a fabulous job by using automation tools, eliminating various organizational bottlenecks, etc. They wow'ed the rest of the organization with their incredible, consistent delivery of value. One of my former students, Dmitri Zimine, gave a presentation at the XPToronto group where he talked about the incredible level of trust that developed between his team and the rest of the organization after consistently, iteration after iteration after iteration meeting their commitments.
All of this is only possible by a rigorous application of timeboxing, careful and consistent task breakdown, and good, honest tracking of results. I wrote a previous article called Seventeen Tips for Iteration Planning. Look it over and see what new ideas you can apply in your situation. If you are frustrated by a team continually over-committing, you will find a lot of valuable advice there.
As a parting shot: consider how you feel right now. Are you stressed out? Over committed? Failing to meet your commitments? Feeling guilty? Working insane hours? Not spending enough time with your family? Killing yourself!?
What about the team or organization you work in? Is it constantly being bombarded by problems it can't handle? Surviving on pure heroics?
I can't tell you that following a careful iterative planning approach will fix your problems... but I can tell you that it will reduce your stress levels, help you (or your organization) make appropriate commitments, and let you see the reality of your situation (good or bad).

The Agile Zealot's Handbook
This is great! I often call myself an Agile Zealot to my clients. (Usually, they smile... and if they don't I tend to have a short relationship with them!) So here it is, the Agile Zealot's Handbook.
And, since I've got a dead horse lying around waiting to be beaten up some more, I've re-written it (the Agile Zealot's Handbook, not the dead horse) to be non-software oriented. Presenting... the new and improved... non-software oriented... readable by anyone... Agile Zealot's Creed:
VALUE
IF you don't repeatedly deliver results
that produce actual value
for a real customer
into your real world environment
frequently enough to respond to change...
TECHNIQUE
IF you're not paying constant attention to technical excellence
with simple, effective tools, processes and reuse
driven by uncompromising dedication to quality
and the discipline to test everything...
LEARN
IF you're not deliberately going
through stages of planning, acting
reflecting and learning
as frequently as you are delivering results
over and over and over...
TEAM
IF your team is not empowered to self-organise,
does not sit together and engage in face-to-face communication,
does not include your customer
and all the necessary skills to make its own decisions and take immediate action...
THEN YOU HAVE COMPROMISED YOUR AGILITY
(and good luck to you... you'll need it!)

End of Iteration 2 ("Capacity") and Start of Iteration 3 ("Automation")
This second iteration when much better than the first. I committed to an amount of work that was much closer to my real capacity, and I stayed more focused on that work. Here are the results of my demo, retrospective and planning for Iteration 3 which I am calling "Automation" for reasons which will be described below.
Demo
I committed to the following items from my Work Queue:
- 1 day intermediate team course
- phone consult details
- QA/tools coaching
- email proposal
- get template from them
- collect hours
- collect receipts
- image receipts
- currency convert receipts if needed
- type up hours
- type up receipts
- email/submit
- 4 hour task
- 4 hour task
- 4 hour task
- 4 hour task
- 4 hour task
- 4 hour task
- 4 hour task
- 4 hour task
- ping Contact1 "V"
- ping Contact2 "N"
- ping Contact3 "M"
- ping Contact4 "S"
- ping Contact5 "V"
- air reservations
- prepare visa application
- submit visa application
- hotel reservations
- equipment
- invoice 1
- invoice 2
I also added these in the middle of the iteration (which is really a "no-no", but I did it anyway to my regret).
- change individual entry archive template
- remove technorati links from 6 articles
- rebuild site
- work with Alexei on structure
- incorporate Alexeis feedback on writing
- work with Alexei on layout and design
What did I actually get done? Here are the stats:
For Iteration 002 - "Capacity":
# Work Queue Items At Start: 5
# Work Queue Items Completed: 3
# Tasks at Start: 32
# Tasks Remaining: 17
What is scary is that my velocity is exactly the same in terms of number of tasks: I really need to start my iterations with only 15 tasks.
Anyway, what I need to do for my next iteration is schedule my "demo" with my other stakeholder (my wife Melanie). Demo'ing to myself in the wee hours of the morning is not really practical in terms of my overall goal for this project (running my business at a sustainable pace).
Retrospective
Here are the things that went well:
- Came much closer to getting everything done that was in my iteration. This was great - I continued to use Tiddly Wiki to track my Work Queue and Tasks.
- Felt less stress. Although I still worked very hard, I was not worried nearly as much about the things still on my Work Queue that weren't in this iteration. I also decided on certain boundaries to work: generally work 4 to 6 hours during the day and another few hours after lights out (usually after 11pm).
- The prioritization worked well - didn't feel impelled to do too much that was _not_ in the iteration. Althought I did take a couple more items in, it was more because of opportunity than anything else. My brother Alexei wanted to help me with my book (for example). Next time around, perhaps I should be more explicit about negotiating with myself about taking something out of the iteration if I bring something in.
Here are the things that need improvment:
- Get even better at judging capacity and committing to an appropriate amount of work. The numbers speak loudly! This next iteration I have to limit myself to 3 items from the Work Queue and about 15 tasks. I have to remind myself that I can always bring more work in if I complete my work early and I still have time.
- Care with long term scheduling - made a mistake in my scheduling with a Client - hopefully it will be okay! This is a bit of a nit, but I need to keep my daybook up-to-date even with long-term stuff.
- Spending time with my family - e.g. playing with kids, helping around house, assisting with homeschooling. This was better than I was doing in Dec., but I need to continue to improve here. I would really like to work with Justice and Haifa on learning Chinese. We've got tons of materials to do it, just need the discipline to get through it together.
Planning
Okay, maybe I'm a glutton for punishment, but I've decided on four items from my Work Queue:
Client2 Invoice
Client2 Work
Automate Listing of Scheduled Courses on 3 Sites
Client3 Statement of Account
The key one is the automation since that will be an investment to save me time later on. In my task breakdown it looks like this (tasks with an "x" are already done from the previous iteration):
x- get template from them
x- collect hours
- determine expense policy
- invoice R0001-001:
-- collect receipts
-- image receipts
-- currency convert receipts if needed
x-- type up hours
- invoice R0001-002:
-- type up hours
- invoice R0001-003:
-- type up hours
- email/submit
- 4 hours
- 4 hours
- 4 hours
- 4 hours
- 4 hours
- 4 hours
- ScrumAlliance
- Google Base
- Berteig Consulting
- laptop
- Visa
- old Visa
So, that's 4 items from the Work Queue and 17 tasks (the ones with "--" in front of them are sub-tasks... not sure how to handle those, but for now I'm not counting them separately.
I'm really excited about this. It sucks to see that I get so little done in a single week, but on the other hand, knowing my capacity allows me to understand just how much work I have on my plate and how badly I need two things: automation and assistance! I'm going to start with automation, but I'm also looking for assistance. The trouble is that I can't affort to hire someone on a salary... (if you know anyone who would be interested in working on commission/revenue-sharing basis, I would love to talk!).
One final note: I did manage to include my wife Melanie in my planning for this iteration. She seemed pleased :-)

Planning Iteration 0002 "Capacity"
I've completed my iteration planning for my second iteration. As a reminder, I'm doing this because I want to be working only 50 hours per week by July 2007. My sole improvement item from last iteration was to use get better at committing to an amount of work within my capacity. Here's what I have planned:
I have included my complete list of work to be done broken down into tasks. It is anonymized:
Client1 Proposal Writing
- 1 day intermediate team course
- phone consult details
- QA/tools coaching
- email proposal
Client2 Invoice
- get template from them
- collect hours
- collect receipts
- image receipts
- currency convert receipts if needed
- type up hours
- type up receipts
- email/submit
Client2 work
- 4 hour task
- 4 hour task
- 4 hour task
- 4 hour task
- 4 hour task
- 4 hour task
- 4 hour task
- 4 hour task
India Training
- ping Contact1 "V"
- ping Contact2 "N"
- ping Contact3 "M"
- ping Contact4 "S"
- ping Contact5 "V"
- air reservations
- prepare visa application
- submit visa application
- hotel reservations
Client3 Statement of Account
- equipment
- invoice 1
- invoice 2
As you can see, I have committed to only five items off the Work Queue for this iteration and they add up to thirty-two tasks. This is more than I indicated last night in my retrospective results. I'm nervous about this in two ways. One, I think that I am under-committing and that I'll get into huge trouble if I don't do more than this. Two, I think that I'm over-committing and that with my brother visiting, even doing this much smaller amount of work will be challenging. Still, I have tried to make both the items from the Work Queue and the tasks smaller than in my previous iteration. I guess I'll see in a week!

First Interation Ending
My first iteration using Agile Work for my business development has come to a close. Here is what I did for a "demo" and retrospective.
Demo
This was simple. I looked at my selected Work Queue items and my tasks and check to see what I had accomplished (finished or partially finished). Here are the statistics (grim and discouraging as they are):
For Iteration 001 - "Beginnings":
# Work Queue Items At Start: 11
# Work Queue Items Completed: 2
# Tasks at Start: 43
# Tasks Remaining: 28
From these numbers, for my next iteration I should probably be hesitant about committing to any more than 2 items from the Work Queue and any more than 15 tasks.
Considering how many work hours I have in a week, 43 tasks is absolutely ridiculous... unless they are really small, which many of them weren't. For example, I had one task as "Integrate part one of Alexei's feedback into my eBook" which when I did it actually took about three hours. Its just one sample, but 3 x 43 is 129 hours and is just not possible for a single human being in 7 days.
Aside from the value-oriented items from the Work Queue, I also did the work to finish a more complete Work Queue. It now has 37 items including those which remain un-finished from this first iteration. It is poorly prioritized, but that will improve over time. As well, I suspect there are quite a few things missing that I forgetting. I should probably get my wife, Melanie, to look over it and make some suggestions. I also have some old "to do" lists for my business which might remind me of some things to add onto it near the bottom.
Retrospective
I did a little mini-retrospective to find the three things that went well this iteration, and the three things that need improvement. I also decided on a clear action item to take to try to improve my next iteration. (Another clear reason to use Card Meeting - worked great for my retrospective :-) .)
Three Things that Went Well:
- Referred to my iteration tasks frequently. I kept my TiddlyWiki up in my browser and checked it several times a day.
- Spent time with my family and friends despite huge workload. We had guests and family visiting and I got some good time in with them. I also spent a good amount of time with Melanie and my kids. I had to make a conscious effort to do this, but since this is the goal of my using Agile Work (to have a good life/work balance), I figured I might as well start making some progress on it right away!
- Had courage to do some development work which required changes to other developers' work. I ran into a problem with some of the work I am doing as a contract. I dug around and realized that any fix I made would be felt by other parts of the codebase as API's changed. I made the fix and then tracked down the dependencies and fixed everything up. Fun!
Three Things that Need Improvement:
- Pay more attention to my schedule / calendar so as to reduce problems with work/family boundaries. Still a loooooong way to go on this one!
- Spend more work time "on-task", rather than on things not on my list. I ended up doing a bunch of work stuff that wasn't in my iteration plan. Partly I did it because I got bored of what I had planned, and partly becuase I forgot to focus on my plans. It would probably help if I had a Process Facilitator breathing down my neck :-)
- Make realistic plans given my capacity for work. This is the biggie! It is going to be very hard for me to keep to a small commitment. But considering the my brother is visiting from Beijing with his wife this week and next, I really have to try to get this right.
It is that last point that I will use as the basis for my next improvement. For my next iteration planning meeting (to be held in the morning after a far-to-brief sleep), I will commit to a maximum of 3 items from the Work Queue. This may mean breaking the items down into smaller bits. I'll talk with the Queue Master (myself) tomorrow morning about it :-)

My First Challenge
Wednesday is nearly done and I'm looking at my list of tasks and cringing! I've only done a few out of the forty for this week. What's going on?!
Well, for one thing, I'm over-committed, and I know it. This is why my goal is to eventually time-box my effort to 50 hours per week. As it is, I expect I'll have a few more short nights this week in order to get even a reasonable amount of my commitment done.
Also, I've been cherry-picking. I'm doing the easy/nice/comfortable tasks first. I'm avoiding the paperwork tasks. I'm avoiding the administrative tasks. These are the ones that I hate and I always procrastinate about. (Hmm... writing this is actually procrastination too... just a few more words and then I'll get back to work.)
Finally, I've got some obstacles which I'm not sure I will overcome this iteration. First of all, I'm spending less time on work than I anticipated. Secondly, I'm getting distracted by tasks that are not directly related to my work items, but which seem to be pre-conditions. For example, I need to do a bunch of administrative follow-up for recent courses I have delivered. Part of that is to send of images of the attendees license forms. I've got the images on the SD card in my digital camera. I've also got a lot of other images on there. So, instead of focusing purely on the task at hand, I am actually cleaning up the whole card. Which is getting rid of technical/administrative debt, but it is slowing me down. Hmm... "administrative debt"... that's gotta be a common theme for the procrastinator!
Anyone out there want to write an article for Agile Advice about administrative debt?

My First Iteration Planning
I've done my iteration planning for my first iteration called "Beginnings". The length of my iterations is one week (including weekends). Here is the list of backlog items that I have committed to (some detail removed):
Catch up on Scrum course follow-up work
Advertize future courses
Finish eBook 2nd Draft
- email request for feedback return
- go through feedback
- finish references
- finish diagrams
Invoice
Finalize India Trip
Interview
Meet up with
Continue development work for
I have broken all of these into tasks, but only put here the ones for finishing my eBook since the rest get into lots of private detail.
I'm currently using TiddlyWiki to track my Work Queue, my tasks and my recurring/scheduled duties. I create a new wikiword for each iteration and copy items from the Work Queue into that section. I also have a menu that has links to my daily, weekly and monthly tasks.
I'm not doing any estimation on either Work Queue items or tasks. This may become a problem, but for now I'm going to try doing the work without the estimation overhead.
I also spoke with my wife, Melanie who is my business partner about all this. She agrees that using Agile Work is a good step to take and looks forward to all the benefits of my being more organized :-)

Technical Debt
Last night I was thinking more about the analogy of technical debt. In this analogy, design and quality flaws in a team's work become a "debt" that must eventually be paid back. This analogy is fantastic because it can be taken just a little bit further to understand just how bad defects are...
Debt is sometimes useful. Financial debt can be used for risk reduction, investment, and emergencies. But it can also cause problems. Too much debt becomes hard to manage. If debt maintenance costs more than revenue (minus other expenses), then you're going down!
Technical debt is a little different than financial debt.
Suppose I went into a boardroom full of high-power executives for some large company. (Never mind how I got there.) And I pitched this fabulous idea: I'll give them a bunch of money for them to use for operations, expansion, whatever. All they have to agree to is that I choose the interest rate when I ask for repayment... trust me!
I would be thrown out of that room so fast!
That is what we do when we encourage teams to take on technical debt.
There is no way to know the interest rate on a defect. Part of the cost of a defect is obvious: how much time and materials will it take to repair the immediate problem. (Although even that is often hard to measure.) But there are also lots of non-obvious and probably non-measurable costs. How much effort will it take to get to the root cause of the defect so that it doesn't occur a second time? How much will it affect our "goodwill" and thus reduce further and repeat sales? How much will the existence of one defect hide the existence of other defects (with their own costs)? How much will the defect demoralize the team and increase staff turnover or reduce productivity? How much of an opportunity will the defect create for competitors? How much will the defect increase maintenance and support costs?
In other words, every time someone asks a team to let quality slide, they are asking the team (and the organization) to take on debt with an unknown interest rate. Which is lunacy.
Read more about this:
Voluntary Technical Debt - James Shore talks about a situation where a conscious decision to take on technical debt led to positive results.
Technical Debt: The Threshold of Acceptable Pain - Steve Bate talks about skill and sensitivity to technical debt. Here's a great quote from this article:
What if someone has a very high threshold of pain? I’d expect to see lots of crud (technical debt) in their code.... The high threshold developer doesn’t mind spending weeks on new features that would otherwise require days or hours with clean code. And they don’t mind staying at work all night fixing bugs before a major release or spending countless hours babysitting the production system after it’s been released. It doesn’t seem to bother them to spend significant time away from family and friends or to have limited time or other interests and hobbies. ...they sometimes experience pleasure at being the “hero” who saved the company from the bugs they created.
An Incremental Technique to Pay Off Testing Technical Debt - Johanna Rothman talks about technical debt and describes a simple risk-oriented approach to reducing it.

Peformance Goals - The Wisdom of Teams
As I continue my enthralled read through "The Wisdom of Teams: Creating the High-Performance Organization
The Performance Goal
This concept and practice is an essential condition for a team to become a high performance team. The Performance Goal is a specific, measurable, challenging goal that is given to and/or adopted by the team. It is a statement or description of a goal that answers "why?" and "what?" questions, but specifically avoids answering "how?". It is not a description of activities, it is a statement of desired results. The team is left with the full authority to answer "how?" and implement it.
This concept is essential for setting the initial boundaries of self-organization. By defining "what" and "why", the team is left free to be creative about the solution. The Performance Goal is also essential to building team accountability (as opposed to individual or externalized accountability). Every action, plan, mistake and success are oriented around the Performance Goal.
From the book:
The hunger for performance is far more important to team success than team-building exercises, special incentives, or team leaders with ideal profiles. In fact, teams often form around such challenges without any help or support from management. Conversely, potential teams without such challenges usually fail to become teams.
I would also like to point out a great blog entry I found that shows some of the other side of dealing with teams and present some cautionary words about the potential pitfalls of working in teams.
In an Agile Work environment, the starting point for a performance goal is simply the delivery of valuable work at the end of their very first iteration. This is often a substantial challenge to a team and an organization. For some teams that have worked for a long time in a "waterfall" or phase-based project environment, it can be almost unthinkable that valuable results could be delivered in one tenth or one twentieth of the "normal" amount of time.
However, simply delivering value at the end of each iteration is probably not going to sustain the development of a high performance team for very long. Rather, the overall objective or goal of the project has to be important and compelling. Much work these days is _not_ important and compelling. In fact, many people become cynical about work because they are stuck doing a high proportion of work that is bureaucratic or due to chaotic circumstances.
As a reminder, the books "Good to Great
I frequently work with organizations where a team has been formed up, told to use agile methods, and then also told how to do their work. Really great examples of this are things like: "we want you to self-organize, but you have to build this huge system using J2EE." The the problem with this is simply that it may in fact be ten times less expensive to build the system with Ruby. However, someone has decided (possibly for defensible reasons) that J2EE is the technology platform that must be used. In this circumstance, someone external to the team has stepped over the boundary of "why" and "what" and also included some "how" in the team's goals. The team is not even allowed to consider the possibility that something might work just as well and be much less expensive. Not only that, but the stakeholders haven't even really stated "why" the system is being built and so the team can't evaluate technology choices. There is no standard around which to self-organize. I admit that I am using a simplistic example here, but the pattern is something that I have seen over and over again.

How to Avoid Context Switching
Given the huge interest in the article by Dmitri Zimine about context switching, and despite a couple of good articles about how to determine iteration length, there has been no empirical method described, only reasoning processes. This article describes a simple method to quickly determine iteration length by experimental means.
Step One
Start with an iteration length that feels right. Use the two articles below to try decide a reasonable length. In software development, this should be no longer that four weeks. In larger volunteer communities it might be as long as three months. In a work environment where you have to deliver daily, your iteration length might be two hours.
Step Two
Build your Work Queue, and plan your first iteration. Mark the tasks that come out of your iteration planning meeting so that you know that they are tasks that were planned. As you go through this first iteration, track all the interruptions you get by writing up a task for each interruption. Each interruption task should be marked so that you know it was an interruption. If you are using note cards on a visible task board, I like to have "normal" tasks on white cards and interruption tasks on fluorescent orange cards to help them stand out!
Step Three
At the end of your iteration, determine which interruption tasks could have been deferred. In other words, determine which were truly urgent and needed to be handled in the already short time of your iteration, and which could have been put on the Work Queue, prioritized, and therefore deferred to a later iteration. This will require collaborating with your Queue Master and possibly other stakeholders.
Step Four
Count how many non-deferrable interruption tasks your team had in the iteration. For this experimental method, you can assume that this is going to be your normal number of interruptions. Divide the length of your iteration by the number of non-deferrable interruptions. For example, if you had a ten day iteration, and two non-deferrable interruptions, you would have a result of five days. Also consider what was the maximum reasonable response time for these non-deferrable interruptions. The lower of these two values becomes your experimentally determined iteration length. But you are not quite done!
Step Five
Do it all again to verify your iteration length. Note that because of your shortened iteration length, you hopefully will have far fewer non-deferrable interruptions. After your second (shortened) iteration, you can adjust the iteration length shorter if necessary... but don't adjust longer (for now).
I've worked with enough teams to know that for a substantial portion of them, this method would result in very very short iterations. In the software world, a team is often asked to work on a project and support their previous project. This support work tends to mean dealing with various bugs in deployed software. This is one reason why I have become such a strong advocate that quality is not negotiable.
I worked with one team that did something similar to this method (although not as rigorously) and we decided that we needed to try an iteration length of two days. This was painful for the team, but they badly wanted to build trust with their stakeholders. Their interruptions were causing them to constantly fail on their commitments. By switching to these two day iterations, they were able to defer the bulk of their interruptions and meet the commitment they made as a team in the iteration planning meeting.
Articles about iteration length:
Mike Cohn's article: "Selecting the Right Iteration Length for Your Software Development Process"
Mishkin Berteig's article: "The Pros and Cons of Short Iterations"
Now that you have gotten to the end of the article, I can admit something to you: this article is badly named. It should be named "How to determine how often to context switch so that you can meet your commitments and build trust with your stakeholders."
What this article doesn't help with is the pain of context switching. The teams that I have see that use short iteration lengths all find ways of making context switching less painful. Automation, good tool choices, workspace arrangements, etc. all play a part in this. But there is no secret ingredient to make context switching painless. Sorry!

The Case for Context Switching
Recently, Dimitri Zimine wrote an excellent little story about context switching. Joel Spolsky writes in "From the 'You Call this Agile' Department":
Dmitri is only looking at one side of the cost/benefit equation. He's laid out a very convincing argument why Sarah should not interrupt her carefully planned two week iteration, but he hasn't even mentioned arguments for the other side: the important sale that will be lost.
Okay... I'll bite.
Let's look at that argument from the perspective of the sales person first since that is where Joel's concern starts:
The Sales Guy Perspective
"I need the 'ezhibal' feature now! Big bucks coming soon if we can get it now."
Let's suppose that this urgent email has come in somewhere near the start of our two week iteration. The normal response to this in Scrum is to push back a little. The ScrumMaster says something to the effect of: "Look if you wait 7 days we can put this on the top of the list for our next iteration."
First reaction, and it's a normal one, is for Sales Guy to freak out. I've actually heard people saying things like "You're going to lose your job over this! I'm getting the VP involved and he's not going to like it" and then they stalk off to find the big dog to come and bark at us. Anyway, let's pretend that the Sales Guy is willing to be reasonable and not instantly escalate the "problem". So what he actually says is: "Look, this is super important, it'll probably only take a few minutes for us to talk about it and then we can figure out how long it will take to fix. Let's just do a quick phone call and yadda, yadda, yadda, blah dee blah..."
Enough of the Sales Guy perspective.
Nowadays, if I'm in this situation, I do a value assessement. I tell the team to keep working on their plan, nothing's changed yet, and I sit down with Sales Guy and the person who's sponsoring the current work and we start a discussion about the options of which there are really only two that work in Scrum:
- Stay the Course
- Cancel the Iteration
First, let's talk about how we decide which option to take. Then we'll talk about why.
Deciding on the option is easy. You look at the value of the work currently being done and compare it to the value of the work that Sales Guy needs. You take into account probabilities. If Sales Guy doesn't have a signed contract, then it's hard to day if there's going to be any real revenue from the 'ezhibal' feature. Still, you might be able to do an assessment of the probabilities based on your level of trust and history with the client, etc. You also need to take into account the time value of money. Does delaying the current work have consequences for another client or stakeholder? What is the cost of those consequences.
This is a relatively simple cost/benefit analysis and comparison. If you're not comfortable with money and numbers and spreadsheets, you better get comfortable!
Okay, so we have a way of comparing the two bits of work. Now let's look at the two "allowed" responses and a third "bad" response.
Stay the Course
Turns out that the potential benefit of the stuff Sales Guy wants is not quite as high as the potential benefit of the stuff that Suzie Stakeholder prioritized for the current iteration. Well, that's easy. Put the request from Sales Guy in our prioritized list of work and get to it when there is an appropriate level of benefit relative to the other work.
Cancel the Iteration
The stuff Sales Guy wants is super-valuable. So let's get the whole team to stop what they are doing and everyone supports this very valuble work. Stopping the whole team is appropriate because obvioulsy, the stuff they're working on isn't as valuable. Oh, and because we treat a team as a unit in Scrum. And because the team needs to commit to work, not individuals. This isn't so obvious... more later.
Peel Sarah off to do the 'ezhibal' Feature
This is what normally happens, and in a "normal" non-agile environment, it's probably okay. In a non-agile environment, Sarah hasn't made any commitments (she's been forced to agree to dates and scope, etc., but she hasn't made a commitment that she is empowered to live up to). So if she goes off and does this one little thing, it probably will be just business as usual. In an agile environment, the team has made a commitment and doing this work this way invalidates the team's commitment.
Why do we do it this way? The main reason is around trust and commitment. Yup, it's that soft icky stuff that we're so incredibly bad at that customers think that bugs are normal, that management shoves the kitchen sink into projects in the frustrated hope that they'll get something out of the IT team at the end of the project. Sound familiar to anyone?
Anyway. An iteration is a commitment. It is a firm and solid commitment. The team as a group of smart and honorable people is making a definite commitment to the rest of the organization to get a certain amount of work done in a fixed amount of time. In return, management is agreeing to give the team every support in reaching this commitment. When a team is new at this, they might get it wrong. But having done this with dozens of teams now, I know that after a few tries, the team gets the hang of it and commits to appropriate amounts of work, and management provides appropriate levels of support.
This commitment is essential for developing trust. And anything that comes in the way of the team meeting its commitment is considered "BAD". An obstacle to do away with.
This is interesting, because Joel's second example is about defects. And I strongly agree that defects are "BAD" and need to be dealt with at a very high level of priority. The reason is simple: they prevent a team from meeting its commitment.
One team I was coaching was constantly bombarded by these types of it'll-just-take-a-few-minutes-need-it-asap requests. They had many stakeholders and very very limited resources to service these requests. They had several small projects that were taking literally years to do because they couldn't get enough concentrated time on any one thing. This was considered normal and good in their environment.
The trouble is, no one had really looked at the overall consequences. Everyone was doing local optimization. For us geeks, we all know that local optimization is something to be avoided if possible. We climb a peak only to discover that we have to climb back down a ways to get up to the higher peak we now see is next to this one. We climb up that one only to discover yet another higher peak even further along thus requiring us to climb down and up again... When really what we should have done is stepped back a ways, looked at the lay of the land and said, "hey, that peak over there is the highest of them all, let's go climb that one."
Scrum helps us avoid local optimization by forcing all feature requests for a team to be prioritized in a list of work, and by allowing the team to complete small pieces of work so it actually gets _something_ done that you can learn from.
Joel said:
Agile is not supposed to be about swapping out one set of bureaucratic, rigid procedures for another equally rigid set of procedures that still doesn't take customer's needs into account.
True enough! But it also demonstrates a serious lack of understanding about what is being done in Dmitri's example! First of all, without being agile at all, it is possible to switch from 18 month projects to two week projects. Both can be bureaucratic as you please (well, actually, there's only so much bureaucracy you can cram into two weeks and still get something done). The shorter projects will allow you to be much more responsive to customer needs... by definition!
So what happens when you add in all the other things that agile really is about? Transparency. Truthfulness. Creativity. Learning. Meta-Learning. Prioritization. Self-Organizating Teams. Eliminating Waste.
Well, first of what you get is something that's damn hard to do right. It goes against almost everything we've been taught to do: the extreme of heroics of the extreme of careful planning and process.
Secondly, what you get is something that needs safety zones and meta-rules. Like mutual, freely-given, team-to-stakeholders commitment. Like assuming positive intent.
And thirdly, what you get is an environment where not only is the business getting what it needs more than it used to, but also, the team likes working with the business, and the business likes working with the team.
I admit that the point Joel is making isn't too different. Yes: look at the costs and the benefits. But agile isn't quite about instantaneous responsiveness. That's a red herring and I'm suprised that Joel threw it's stinky carcass into the discussion. Agile is also about balancing that responsiveness with the overall view of value for the team and the organization. The tool for doing that is the prioritized list of work, not the email message from Sales Guy to Sarah.

Scaling Agile Projects
More and more, organizations are applying agile methods to large projects or efforts that require more than a single team. There are three dimensions or concerns of coordination. It is critical that all three be addressed, but there are many ways of addressing them. Here I will simply list these three types of coordination and make some simple suggestions of how to implement them.
I have now had the opportunity to work with several clients where they are applying agile methods to projects with budgets that are greater than $10,000,000. All of them are using multiple teams to work on the same overall project/program. Out of this experience (along with some good reading along the way), I have come to understand that the following three types of coordination are the essential ones:
Value
In order to maintain the "early and frequent" delivery of value that agile methods propose, it is important that the work of the effort be coordinated to maximize early delivery of value. From this perspective, there are often many cooks in the kitchen. I have seen a "Product Owner Team", a "Customer Team", and a number of variations of this type. In order to do the coordination work effectively, it is still necessary to make sure of two things:
- Maintain a single Work Queue that prioritizes the work and from which all the teams select items.
- Have a single person in the "buck stops here" role who can make final binding decisions about work priority and content.
These two items have some implications for the organization.
First, the teams must be organized to be generalist: each team should be able to handle any item on the Work Queue. Not every team is going to be equal in abilities and this can be accomodated in a number of ways. My favorite so far comes from an excellent agile coach Dave West
The second implication is that the customer or product team (Queue Master) must have the availability to support multiple teams in a timely fashion. Ideally, there are individuals on each team who can make judgement calls about features, functionality, constraints etc. on the work and provide quick answers to questions. This is not always easy since the people doing this often have a special area of expertise and it is difficult for them to work outside this area. Just as team members are asked to become generalizing specialists, so must the people who are responsible for determining value in a project.
Process
An agile process endeavors to provide a minimally structured way to do three things: deliver value early, then learn about what is high in value and deliver that more, and finally, learn how to deliver value more effectively.
That third activity, learning how to deliver value more effectively, is facilitated by the Process Facilitator. The Process Facilitator keeps a visible list of obstacles and works collaboratively with the Team and the Stakeholders to resolve obstacles on the list.
In a multi-team environment, there may be a single Process Facilitator working with each team. Like with the Work Queue, it is often necessary to have a single Record of Obstacles for the entire project.
Technique
People develop skill and knowledge in the use of their tools. Most types of work have a special vocabularly that only makes sense to other people also doing that work. For example, the field of computer programming has programming languages, integrated development environments, build tools, testing tools, algorithms, and a host of other techniques. The field of film-making has cameras, film, directorial techniques, lighting, story structure, it's own esoteric vocabulary, and other techniques. Likewise for construction, law, medicine, drama, education, etc. etc. etc.
In a large Agile Work project, teams need a way to coordinate their technique to produce integrated, consistent and compatible results. As well, individuals on the teams may discover or create new ways of doing things that would be valuable for the other teams to know about and use.
The most effective way of coordinating technique across teams is for strong members of each team to gather regularly to review the way work is being done. This "technical support group" can look at tools, reuse, automation, patterns, vocabularly and any other "how to" aspects of the work. It is critical that these people are actively involved in work being done on a delivery team so that efforts of the technical support group do not become academic or "ivory tower".
In certain environments, it may be useful to have this techincal support group become a team with a clear allocation of time apart from the regular delivery teams. In this case, this technical support team would have its own Work Queue that consisted of requests, ideas, concerns, and opportunities presented by the regular delivery teams.
I have seen all three aspects of coordination implemented in large multi-team projects. Some of the common challenges include:
- Generalist Teams.
It is difficult enough to create cross-functional teams where people are willing to become generalizing specialists. While it is important to create generalist teams, most organizations should expect to set up non-ideal specialist teams (sometimes by line-of-business) and support their development into generalist teams. - Technical Coordination.
Often organizations have a design or technical review group composed of the "experts". These people are often isolated from the actual work being performed by the teams. It is difficult, yet critical, that these people actually be involved in day-to-day work on the teams.

Agile Team Launch - a Howto Guide for Managers
Starting off on the right foot is just as important as it ever was. However, with Agile Work, this takes on a significantly different meaning than it does in other methods as the emphasis of what is "right" is also significantly different. This is a short guide on how to successfully launch a team using Agile Work.
0. Do what you need to in your organization to get a project and its budget approved. This usually involves some sort of business case, project charter and approval process. This may sound obvious, but the organizational support that this provides is essential.
1. Management must have a basic understanding of the method and in particular the roles: Queue Master, Process Facilitator and Team. This can be accomplished in a number of ways: reading, attending a workshop, or bringing a coach in to do a brief presentation. By "management" is meant at least the person sponsoring the launch of an agile team.
2. Individual people must be identified to fill the Queue Master and Process Facilitator roles. At first, these people should be assigned to these roles full-time and relieved of their previous duties. Ideally, the people filling these roles are volunteers from a pre-selected group of appropriate candidates.
3. The Queue Master and Process Facilitator must both get some initial training. For this, the following books are recommended for both roles: Agile Estimating and Planning (Robert C. Martin Series)
4. Form up the team. Getting this right is not easy: the team needs to remain relatively small (5 people is about right), but at the same time include people with all the skills necessary to deliver the whole project. You need people who are good at the various technical skills needed, the people skills needed, the problem-solving and analysis skills needed, and the administrative skills. All these people need to be part of the team right from the start. Again, for emphasis: do not start the project before all these people and their skills are dedicated to the team and they have been relieved of their previous duties. Forming the team includes logistical concerns such as where the team will sit, making sure they have the right equipment for their work, etc.
5. If you are trying agile for the first time, don't consider using a distributed team or off-shore resources. Nor telecommuters. This type of stuff is better left for once your organization has more experience with agile methods.
6. Provide initial training to your team. Include the Queue Master and Process Facilitator in this training (they are considered part of the team). Also include any significant stakeholders in the results of the project. Give them, at a minimum, a one-day introduction to agile.
7. The Queue Master creates an initial Work Queue. The rest of the team should participate in this process. The creation of this Work Queue must be timeboxed. I advise that it should only be given 1 or 2 percent of the overall project time. Decide before you start on how long will be given to this. The end result of this is a Work Queue that has some number of work items defined, understood by the team, valued, costed, and prioritized. The Work Queue does not have to be "finished". It is more important to hold to the timebox than to get the Work Queue "right". Remember that the Work Queue will continue to be refined as the team progresses in its work. Do not under any circumstances create the initial Work Queue in the absence of the team!
8. Run a brief project workshop. In this workshop, the team answers basic questions about the nature of the project run with agile methods such as:
- what is the length of our iterations?
- what are the team's core hours (when do all the team members commit to working together as opposed to working on administrivia)?
- what other teams/groups do we need to work with?
- are we missing any critical skills (now that we have seen the initial Work Queue)?
- what are the priorities of the project (quality, scope, time, budget, experimentation, etc.)?
9. OPTIONAL ITEMS:
- Consider doing a workshop on corporate culture and agile methods to help the team understand some of the challenges it will face and where it can find support
- Consider doing some initial team building exercises. Particularly if people on the team haven't worked together previously, this can help the team to get over some initial hurdles.
- Consider getting junior members of the team some additional training on the techniques, technologies or tools used in the team's work. This can be arranged so that it is done simultaneously with some of the team's early iterations.
- Consider engaging a coach or mentor for your Process Facilitator. This coach can be someone inside the organization who has extensive experience with agile methods or an external consultant who comes for a limited time to help your Process Facilitator.
None of these optional items should unduly delay the start of the first iteration.
10. Start your first iteration. There should be little or no delay or waiting between the creation of the team and the start of the first iteration. At this point the Process Facilitator is responsible for the process, the Queue Master is responsible for the value delivered, and the Team is responsible for delivering results.

The Seven Core Practices of Agile Work
Agile Work consists of seven core practices. These practices form a solid starting point for any person, team or community that wishes to follow the Middle Way to Excellence.
Self-Organizing Team
Any group of people that wish to be an Agile Team need to take the initiative to determine for themselves how they are going to work (process) and how they are going to do the work (product). The term "team" really applies quite broadly to any size group of people that are working together towards a common goal.
Teams go through stages of development as they perform their work. The most important result of team development is the team itself, and not the specific skills and abilities that the individuals learn.
If the team is part of a broader organization, that organization must give the team the authority, space and safety to learn to be self-organizing. The organization's leadership is responsible for determining the "why?", some constraints on "how?", and then letting the team respond to the need as best as it can.
Also Known As: Whole Team (Extreme Programming), Cross-Functional Team (business management).
Deliver Frequently
Agile Work uses short fixed periods of time to frame the process of delivering something of value. Each of these iterations or timeboxes is structured so that the team or group actually finishes a piece of work and delivers it to stakeholders. Then, the team builds on what has previously been delivered to do it again in the same short amount of time.
The sooner that valuable results can be delivered, the more value can be obtained from those results. This extra value is derived from opportunities such as earlier sales, competitive advantage, early feedback, and risk reduction.
There is an explicit tradeoff: the shorter the time to delivery, the smaller the piece of value will be. But, like investing in one's retirement account, the earlier you start, even with small amounts of money, the better off you are in the long run.
Also Known As: Sprint (Scrum), Iteration (Extreme Programming), Timeboxing (generic), Time Value of Money (accounting).
Plan to Learn
Every type of work is governed by a Horizon of Predictability. Any plan that extends beyond this horizon of predictability is bound to fail. Agile work uses an explicit learning cycle tied in with the planning of work to accomodate this inevitable change.
First, a goal is required. This goal can be long-term. Teams using Agile Work then create a queue of work items to be done in order to reach this goal. Each iteration, some of these items are selected, finished and then the queue is adjusted. The changes in the work queue are based on external factors, and learning that the team does as it goes.
One of the most effective methods for the team to learn about how it is doing its work is the retrospective. After each delivery of results, the team holds a retrospective to examine how it can improve.
Also Known As: Inspect and Adapt (Scrum), Kaizen (Lean), Adaptive Planning (generic).
Communicate Powerfully
A team needs to have effective means of communicating, both amongst team members and also to stakeholders. To Communicate Powerfully, a team needs to prefer in-person communication over distributed communication. Synchronous over asynchronous communication. High-bandwidth over low-bandwidth communication. Multi-mode communication over single-mode communication.
The results of failing to communicate powerfully include wasted time for waiting, misunderstandings leading to defects or re-work, slower development of trust, slower team-building, and ultimately a failure to align perceptions of reality.
The single most effective means to communicate powerfully, is to put all the team in a room together where they can do their work, every day for the majority of the work time.
Some types of work do not lend themselves to this approach (e.g. creating a documentary video), but every effort should be made to improve communication.
Also Known As: Visibility (Scrum), Whole Team and Team Room (Extreme Programming), War Room (business management).
Test Everything
Defects are one of the most critical types of waste to eliminate from a work process. By testing everything, by driving all the work of a team by creating test cases to check the work, a team can reach extremely high quality levels. This ability to prevent defects is so important that only an executive level decision should be considered sufficient to allow defects into a work process. Quality is not negotiable.
In Agile Work, removing a defect is the only type of work that takes priority over any new features/functionality/production. If the end result desired is to maximize value, then removing defects is an important means to that end.
A team has an ethical duty to discover new ways to effectively test their work. This can be through the use of tools, various feedback mechanisms, automation, and good old problem-solving abilities.
Also Known As: Canary in the Coal Mine (Scrum), Test-Driven Development (Extreme Programming), Defects per Opportunities (Six-Sigma).
Measure Value
Since Reality is Perceived, it is important for an agile team and organization to have a clear method of describing and perceiving what is important for the organization. Measuring value is a critical method for describing and perceiving what is important.
A single metric can be used to drive all the measurement and goal-setting and rewards in an organization. All other measurements are secondary and must be treated as such: limited in use and temporary.
There are many things which are easier to measure than value. It is often easy to measure cost, or hours worked, or defects found, or estimate vs. actual... etc. However, all of these other measurements either implicitly or explicitly drive sub-optimal behavior.
Also Known As: Measuring Results (Scrum), ROI (business management), Economic Driver (Good to Great), Running Tested Features (Extreme Programming).
Clear the Path
Everyone in an organization using Agile Work takes responsibility for clearing the path, removing the obstacles that prevent work from being done effectively. Clearing the Path doesn't just mean expedient, quick fixes to problems, but rather taking the time to look at an obstacle and do the best possible to remove it permanently so that it never blocks the path again.
In the Agile Work method, the Process Facilitator is the person who is responsible for tracking obstacles and ensuring that the path is cleared. To do this, the Process Facilitator maintains a Record of Obstacles.
Clearing the Path is sometimes painful work that exposes things we would rather not deal with. As a result, it is critical that people build their capacity for truthfulness and work to develop trust amongst each other. Building a capacity for truthfulness is not something that can be done by using an explicit process.
Also Known As: Removing Obstacles (Scrum), Stopping the Line (Lean).
Remember also, that these practices must always be viewed and implemented in the context of the Agile Axioms. These axioms provide a check to ensure that the practices are not being applied blindly, but rather applied appropriately to the given situation.

Agile Adoption Stages for Teams
We know that teams go through identifiable stages of development: forming, storming, norming and performing (1). What exactly does this look like for an Agile team?
Forming
Here the team is typically innundated with three sources of new information: the Agile process and practices, the nature of the project and the other people in the team. This can be overwhelming and people will react in diverse ways: calm wait-and-see, rebelliousness, passive-aggressive, excitement, etc. If the team has an effective coach or mentor shepherding them through this, then feelings will tend towards excitement. The reality of learning so much at the same time will make the first few weeks of the team's time together quite exhausting. People will be actively fighting old habits, and people around the team will be asking lots of questions. Retrospectives will usually show that the team is impressed with their own teamwork and communication and will also show some disappointment with specific agile work practices.
Storming
After only one or two iterations, the team will transition into the Storming stage of development. Because Agile methods "front-load" the learning and the crisis, this forming stage comes fast, but it is also relatively mild. (Front-loading the learning means that all the problems that an organization has that hold it back from delivering quality work quickly are made visible in the first couple of iterations.) People are not used to a project being in crisis right at the start. It is critical for a coach or mentor or manager to be aware of this effect and expecting it. Again, for emphasis: an Agile project is in crisis immediately!... and this is perfectly normal and healthy. If the organization and the team are able to find means of dealing with this early crisis, then the project will continue and build larger and larger successes. On the other hand, if the organization or the team try to ignore or hide the problems, then very quickly work will revert to the old way: bureaucracy or chaos.
Norming
After about four to eight iterations, the team will reach a fairly comfortable place: the basic agile processes and practices are understood, the organization and the team have removed some basic obstacles to getting work done (and consciously left some obstacles in place in all likelihood), and everyone on the team has a basic level of comfort with their role. The challenge at this stage is to avoid falling into the trap of complacency. Although comfortable, this level of performance is probably not all that much better than the old way. There will be real advantages: regular delivery of work, good communication between stakeholders and the team. But there will be many obstacles still to be removed, and the team has a long way to go in its development. If the team becomes complacent, then it is critical that a catalyst be introduced to incite the team to further development. Often, this can be as simple as a systematic and intensive program of capability building. As team members learn and practice new skills: process skills, technical skills, people skills, strategic skills, business skills... and as they become more and more aware of each other's capabilities, they will also become more and more aware of areas for improvement. Incentives need to be provided to help team members focus dilligently on self-improvement and team improvement. The iteration retrospectives become critical to help with this process... the tricky bit is that this is the stage when people start to think the retrospectives are no longer necessary!
Performing
The transition into the Performing stage for an agile team is gradual and happens over a fairly extended period of time. The definition of "getting to done" will gradually expand to allow the team to go from zero to full delivery of the end results every single iteration. There will be a temptation to split up the team and use these experienced team members to seed new agile teams - resist this temptation! Breaking up the team at this point destroys the value of time and effort invested in the team. It is much more effective to start a new team from scratch. The essence of a performing agile team is not the transferrable knowledge about agile processes and practices. Rather, the most important result of the team-building process combined with the agile process is the team itself.

Follow the Principles and Adjust the Practices
In "Built to Last : Successful Habits of Visionary Companies
Follow the Principles
What exactly are the principles? The foundation starts with Trust and Truthfulness. "Truthfulness is the foundation of all human virtues." Everything we do with agile should be about truthfulness (visibility, transparency) and building trust.
With this as a strong foundation, we can look at the Agile Axioms:
We are Creators
Reality is Perceived
Change is Natural
All of the other principles and practices associated with Agile Work flow from these basic assumptions about the world. We can't prove that the above three axioms are "true". But they either resonate with us or they don't. If they do, then it will be easy to use these axioms as a checkpoint for all the activities we engage in using Agile Work, wherever we apply it.
We are creators... therefore we derive our sense of value from our ability to create. If our creations are accepted by others, our team, our stakeholders or our community, all the better. But fundamentally, this is inherent to us as human beings. However, sometimes this natural drive is suppressed or repressed. In order to activate it, we need to work in empowered teams.
Have you ever experienced inspiration or "flow" or joy when working with someone else? Perhaps you were solving a problem. Perhaps you were playing a musical instrument - jamming - and got into a fertile groove. Perhaps you were teaching your children and created the light of understanding in them. Perhaps you built a beautiful set of bookshelves for your home. Or maybe you told a joke that created a brief moment of genuine levity in a group of friends. We are all constantly creating!
This basic principle then means that Agile Work methods and practices should not be imposed. Taught to us, perhaps... given to us as a template, perhaps... but once we understand the practices and are familiar with them, we should immediately be given the freedom to use the learning cycle to be creative with the process and practices of Agile Work itself. If we do not participate in creation, we become dis-empowered and that eventually leads to resentment or apathy.
Reality is perceived... therefore we need to work hard to build a common perception of reality if we are to work together effectively. We need to amplify our learning. We can't assume that our own understanding of a situation is going to be shared by others. At the very least we need to check: "do you see this?"
Let's recognize that in some way or another we are all blind:
Again, the learning cycle comes into play. The guidance, detachment, love, courage and search we go through all help us to build a common understanding of reality. This allows us to see new ways to apply the Agile Work principles and practices that make sense not only to our context, but also to everyone else participating in the work.
Change is natural... therefore instead of fighting change, we need to anticipate it, adjust to it, embrace it, and be gracious or even enthusiastic. Not only does change happen to us, but we also instigate change. If things get to boring, whatever the circumstance, we find ways to change things. We rebel at stasis and ennui.
Each practice and procedure done in the context of Agile Work must be explicity and implicitly accomodating of change. If a procedure can't tolerate change it will either lead to a dissonance or conflict... or if we are embracing change, then we will modify or discard the procedure. Our creative nature loves to create, but if we become too attached, too "in love" with our creations, we will support them past their point of relevance.
Our latest greatest idea will be good for a while. But eventually change will make it irrelevent.
So we see that all three Agile Axioms are also interrelated.
Our creations will be washed away through change and if we are lucky or wise we will perceive the change in reality - be truthful to ourselves and others - and allow a new creation to take the place of the old one.
When we perceive a certain truth, and try to share that with others, we will be asking those others to change their own perceptions. This change can be difficult and may even require the destruction of a mental model created with love and care over a lifetime. Sensitivity to this loss and encouragement to build a new creation will help build a shared perception... as long as we too are open to new perceptions!
Adjust the Practices
And of course, all this foundation of creation, perception and change must be connected to the practical day-to-day reality of our lives. Our family lives, our work lives, our social lives, our volunteer lives, our intellectual lives, our emotional lives, our spiritual lives... our whole lives.
The Agile Work practices are simple to state:
Manage Ourselves
Deliver Frequently
Adapt our Plans
Communicate Powerfully
Test Everything
Measure Value
Remove Obstacles
These practices provide a starting point. A basic set of activities that will assist you, your team or your organization to advance quickly towards whatever goal you have set for yourselves. The way these practices succeed is by making sure that the Agile Axioms are always remembered and their implications accepted. These practices will set up a virtuous circle by building trust and allowing truthfulness. More trust and truthfulness will allow a fuller and more nuanced expression of the practices...
But if these practices become canonized, if they become a rote process imposed and followed blindly, then it means that we have lost sight of the Axioms. We have forgotten to check our practices against the context of creation, perception and change.
The reason we follow these practices is because we believe that we are all creators, that we can learn from our diverse perception of reality and that change is a force of growth. We don't believe these Axioms because we blindly perform these practices.
This is all available as a nicely formatted pdf: Agile Axioms - a Brief Exposition.

How the Process Facilitator can Help the Team Handle Out-of-Scope Work Requests
Sometimes an agile team is innundated (or maybe just slightly distracted) by requests for individuals on the team to do work for people or groups outside the team's official stakeholders. This can happen, for example, in a corporate culture that promotes the exchange of favors. This past weekend at our Agile Coach's gathering, Deborah Hartmann shared her method of detecting, exposing and discouraging this unofficial work.
The mechanism is actually very simple: track the work in the team space using cards and a variation on the burndown chart.
The Cards:
During the team's status meeting, or any other time that a team member mentions doing some of this outside work, immediately request that that person write it down on a task card. The task card should be visibly distinct from normal task cards: either a different color or a different size or in a substantially different location. The task should also get an estimate in the same units you are using for the other tasks.
For each task identified, contact the person who requested the extra work. If the person who is doing the work has made a committment to the requestor then let the requestor know that the team has accepted the work but that there is a consequence: the team may not get all its other work done on time. As well, the requester should be informed that in the future, all extra work for individuals on the team must be prioritized by the team's product owner.
Encourage the team to reveal this work by mentioning it at the start of the status meeting, in any iteration planning or retrospective meetings, or in any one-on-one meetings you have with team members.
The Burndown Chart:
Now that all the extra work is reflected in cards with estimates, the burndown chart can track this work too. The key difference is that it is tracked as a separate part of the work. If there are 80 units of normal work remaining, and 20 units of this extra work remaining, then the burndown chart will have a mark at 20 and a mark at 100. The mark at 20 should be made in a different color (I recommend red) so that it is highly visible. One ends up with a burndown chart that looks something like this:
The Product Owner:
It doesn't take much more than a single iteration for the Product Owner to get the message loud and clear: this extra work is eating up the team's capacity! The Product Owner now sees the consequences of not being the go-to person for all work items.
Deb's experience with this was that by the next iteration there were no further requests of the team for unofficial work, and the team's capacity to do work for the Product Owner took a nice leap upwards.

Agile or Not Agile?
Every once in a while the del.icio.us tag for Agile turns up something really interesting. This evening, I found this article about the ongoing use of the term "Agile". The article is brief and a little weak, but it brings up a concern that is always niggling in the back of my mind. Interestingly enough, a good friend of mine, Christian Gruber, emailed me another web page of similar import...
In this registration page for Rules of Enterprise Agility, we read about something that really has nothing to do with the Agile Manifesto, nor the Agile Axioms.
Both of these examples are signs of two things:
1. The growing popularity of the term "Agile".
2. The growing dilution of the meaning of the term.
How can we fight this? Should we fight this?
I think it is very important to constantly call attention to the fact that Agile is about the minimum process and tools that can possibly work, and only in the context of valuing individuals, interactions and teams more than those tools and processes.
Trust is the Foundation of Agile Work
Technology, tools, process, even good ideas and good organizations do not create trust. People create trust by being trustworthy: honoring their commitments, striving for excellence, truthfulness, courage. One of the fundamental problems afflicting organizations is the lack of trust: between management and employees, between business and IT, between experts of various sorts, between coworkers.
This lack of trust is institutionalized in many ways including bureaucracy and legal frameworks.
The only way to change this state of affairs is to build trust. And the only way to build trust is to embody trustworthiness in yourself so that by example and by your words you can help others to become more trustworthy.
Agile methods put in place mechanisms that assist in building trust. But those mechanisms are merely a means to an end. Let us never forget that.

Work Item Backlogs as Queues - Agile vs. Lean
A recent discussion on the Scrum Development list (Start of Discussion) provides a good follow up to my parting words in The Art of Obstacle Removal about agile practices themselves becoming obstacles. I have excerpted a small amount of the discussion and added my own comments here.
In the agile community, most of us have bought into and adopted the Agile mental model. But that mental model has assumptions embedded into that may not be correct under all circumstances. Part of that mental model includes the efficacy of the work item backlog as a tool for tracking, prioritizing and communicating work to be done in the future.
I will be the first to say that Agile is far better than waterfall in almost every situation (the exception being the mythical project with stable requirements, business environment, technology and team).
That said, let's look at backlogs from another perspective: if a backlog was the only thing you delivered to the customer, would they pay for it? If you spent even just a few hours coaching a business representative to build a backlog, but there was no team to implment it, would that person really find value in the backlog itself? Would they be able to deliver ROI just from a backlog? I think the answer is a clear "no".
That set of questions may seem silly, but from a lean perspective, they are among the most important questions. Is an artifact/process value-added or non-value-added?
Since the backlog is clearly not a value added artifact/process (pause for effect)... it is waste!
When one is doing agile effectively, the backlog may in fact be one of the larger sources of waste! If the team has a stable velocity, there will come a point when the backlog becomes the constraint on the overall cycle time going from idea to ROI. If the backlog is large/long, and as Mary Poppendieck said if there is more than ...maybe two or three
sprints of work.... in there, then it may be time to find ways of constraining the size of the backlog. I have two suggestions:
Capacity of Team(s):
Find a way to increase the capacity of the team so that the backlog size reduces and then goes into a steady state. This may mean augmenting the staff.
Gate Backlog Items by ROI
(This is just theory to me at this point.) Make it a condition that all backlog items must have a positive ROI. In other words, the cost of building the backlog item needs to be less than the value delivered, taking into account time value of money. Don't let items onto the backlog unless this positive ROI can be demonstrated.
I believe the lack of this second discipline (assigning ROI to work items) is one of the main reasons that most agile methods such as Scrum allow an unlimited backlog size: there is no realistic way to gate the work that gets onto the backlog!
Until teams get to Agile nirvana (stable velocity, continuous delivery of business value, high-performance cohesive teams), having an unlimited backlog seems like a very reasonable thing: it's not the constraint or the primary source of waste. However, eventually the backlog will become a primary source of waste and it needs to be treated in a disciplined manner.
With a stable and well-functioning team, what other ways might there be to reduce the size of the backlog so that cycle time is substantially reduced?

The Art of Obstacle Removal
One of the best ways to go faster is to remove the things that slow you down. This "obstacle removal" is an integral part of many agile methods including Scrum and Lean. Sometimes it is obvious where an obstacle is. There are a few small things that can be done easily to go faster. But to get going really fast, we need to have a deeper understanding of obstacles... and the Art of Obstacle Removal.
What are Obstacles?
An obstacle is any behavior, physical arrangement, procedure or checkpoint that makes getting work done slower without adding any actual contribution to the work. Activities that do add value to our work may be slowed down by obstacles, but are not obstacles in and of themselves.
Obstacles and Waste
Obstacles are the causes of waste in a process. There are many types of waste, and for every type of waste there are many possible sources (obstacles).
Types of Obstacles
Personal
Personal obstacles are related to us as individuals. There are several levels at which these obstacles can show up.
Outside factors in our lives such as illness or family obligations can become obstacles to our work at hand. These obstacles are hard to remove or avoid. Even if we would want to avoid an obstacle such as illness, it is hard to do anything about it in an immediate sense. However, as part of our committment to the group we are working with, we should consider doing things to generally improve our health. Good sleep, healthy and moderate eating, exercise and avoidance of illness-causing things and circumstances are all possible commitments we can make to the group. Likewise, we can make sure our personal affairs are in order so that unexpected events have the least impact possible. This topic is vast and there are many good sources of information.
Physical Environment
Obstacles in the physical environment can consist of barriers to movement or communication, or a lack of adequate physical resources. Sometimes these obstacles are easy to see because their effects are immediate. For example, if a team room lacks a whiteboard for diagrams, keeping notes, etc., then the team may not be able to communicate as effectively.
Other physical obstacles are not so obvious. The effects of physical environment can be subtle and not well-understood. Poor ergonomics take weeks, months or years for their effects to be felt... but it is inevitable. A too-small team room can lead to a feeling of being cooped up and desperation to get out... and eventually to resentment. Again this can take weeks or months.
Here are some guidelines on a good team room.
Knowledge
A lack of knowledge or the inability to access information are obstacles. A team composed of junior people who don't have diverse experience and who don't have a good knowledge of the work they are doing will have trouble working effectively. There may be barriers preventing the team from learning. Common barriers include over-work leading to a lack of time or mental energy for learning. With junior people in particular, there is a lot of pressure to be productive and that can often be at the expense of a solid foundation of learning.
Other times, knowledge-related barriers can be more immediate. If a critical piece of information is delayed or lost this can have a large impact on an Agile team that is working in short cycles. The team may be temporarily halted while they wait for information. Building effective information flow is critical to a team's performance.
Organizational
One of the best sources of information about this is the two books by Jim Collins: "Good to Great" (Review) and "Built to Last" (Review).
Cultural
In organizational culture, one thing I constantly see is a public espoused value of teamwork, but a conflicting behavior of individual performance reviews and ranking. This is cultural. It is also a barrier to the effective functioning of an Agile team. For corporate environments I highly recommend the Corporate Culture Survival Guide by Edgar Schein.
Dis-Unity
Dis-unity is one of the most subtle and common forms of obstacle. Competition, legal and cultural assumption of the goodness of "opposition" and habits of interaction including gossip and backbiting all combine to make united action and thought very difficult.
This is an extremely deep topic. There are many tools and techniques available to assist with team building. If you are interested in this topic, I highly recommend reading "The Prosperity of Humankind".
Removing Obstacles
The ability to identify obstacles and understand why they are causing problems is only the first step in removing obstacles. In Agile Work, the person primarily responsible for identifying and removing obstacles is the Process Facilitator. The Process Facilitator has several approaches available for the removal of obstacles. A process facilitator has similar responsibilities to a change agent.
Direct
Deal with the obstacle directly without involving other people. This can be as simple as getting up and moving an obstacle impairing vision, or as nuanced as running interviews and workshops throughout an organization to gradually change a cultural obstacle.
Command and Control
Identify the obstacle and give precise instructions for its removal to a person who will directly perform the removal. This can sometimes work if removing an obstacle takes a great deal of time, effort or specialized skills that you yourself do not posess. However, the overall approach of "command and control" is not recommended for Agile environments since it is disempowering.
Influence
Identify the obstacle and suggest means to deal with it to a person who has the authority or influence to get others to deal with it. This indirect method of obstacle removal can be slow and frustrating. However it usually has better long-term effects than command and control.
Support
Offer to assist and encourage the removal of obstacles that have been identified by other people. In many respects this is a very effective method. It can assist with team-building and learning by example. People are usually grateful for assistance.
Coaching
Train others on the art of obstacle removal including obstacle identification, types of obstacles and strategies for dealing with obstacles. Observe people's attempts to remove obstacles and give them feedback on their actions.
Creating a Culture of Obstacle Removal
Encourage and measure obstacle removal at all organizational levels until it becomes habitual. In many ways this is the essense of the lean organization.
Strategies for Dealing with Obstacles
Diagrams are a great way of communicating the essense of a concept. Feel free to share the following diagrams with anyone (but of course keep the copyright notice on them).
Remove
Remove the obstacle altogether. This method of dealing with an obstacle is usually the most immediately effective, but is also one of the most difficult methods.
The best way to actually remove an obstacle is to get at the root cause of the obstacle and change that. This type of change results in the longest-lasting and most stable elimination of an obstacle.
Move Aside
Take the obstacle and put it in a place or situation where it is no longer in the path of the team.
In a team's physical environment, this may be as simple as changing the tools that the team is using. For example, if the team is all in a room together, move computer monitors that are blocking team member's views of each other. If there is a useless checkpoint that work results have to go through, get management to eliminate it.
Shield
Build a shield or barrier to hide the obstacle so that it's effects no longer touch your team.
If a team is distracted by noisy neighbors, put up a sound barrier. If a team is unable to see their computers due to late afternoon sunlight, put up window shades. If a manager is bothering the team with meetings or tasks unrelated to the work of the team, then put yourself between the team and the manager (or get someone in upper management to do that).
Shielding is excellent for immediate relief, but remember that the obstacle is still there and may become a problem again if the shield cannot be maintained.
Transform
Change the structure or form of the obstacle so that it no longer affects effectiveness.
In general, this method requires a great deal of creativity and open-mindedness. This is one that works particularly well on people who are obstacles: convert them into friends of the team!
For example if the team needs approval of an expert who is not part of the team, this can cause extra work preparing documentation for this person and long delays while the expert revies the documents. If the expert becomes part of the team, then they are well-informed of the work being done and can give approval with very little overhead.
If done well, this can be a very long-lasting method of dealing with an obstacle. Make sure that the transformation is true and that it takes hold... and beware that the obstacle doesn't revert back to its old nature.
Counteract
Find an activity that negates the effects of the obstacle by boosting effectiveness in another area.
As a coach or Process Facilitator, this is what we spend our time in early in a team's adoption of Agile Work: we get them to work in the same room, use iterations and adaptive planning, we focus them on delivering work valued by the stakeholders as defined by the Product Owner. All these things are enhancing the team's ability to get work done without actually directly dealing with any obstacles.
Watch out for barriers avoided this way to come back and bite you later on.
Removing Obstacles and Learning
Organizational learning, as well as adult learning have a strong relationship to obstacle removal. Organizational learning can be either single-loop or double-loop learning. Adult learning can be either normal or transformative. We can approach obstacle removal from a surface level where we only deal with the immediate symptom, or we can work at a deeper level where we deal with the symptom and its chain of preceding causes. One effective method for examining the deeper causes is the 5-why's exercise.
Obstacles Inherent in Agile
Agile methods do not perfectly eliminate all obstacles. Some obstacles that are inherent in agile methods include overhead due to planning meetings at the start of iterations, the use of a dedicated process facilitator. As well, the use of iterations can become a barrier to certain types of work items: repeating items, investment in infrastructure, one-off tasks that are not directly related to the work at hand.
At some point, our teams will have matured to the point where agile methods are no longer necessary and we can pick and choose what parts of agile we use.
Go Forth and Demolish Obstacles!
As a Process Facilitator, coach, ScrumMaster, manager, change agent or stealth agile advocate, you have the ability and the knowledge to make a big difference in people's lives and in the success of the organizations they work within. Removing obstacles is one of the most important duties you have.
Do you have stories about obstacles you have removed or seen removed that have made a big difference? We would love the hear the anecdotal side of this as well!

Amplifying Learning Through Fostering Critical Reflection
I have written previously about the tendency we have to limit future learning based on previous learning. This tendency has aptly been termed by Mezirow as the central learning problem of adulthood: "that we fail to notice that failing to notice shapes our thoughts and deeds." In Transformative Learning literature a central method advocated for overcoming this learning problem is critical reflection. Critical reflection is the act of becoming conscious of our beliefs and assumptions (Where do they come from? Are they valid? What are their limitations? etc.) and either expanding, validating or discarding them.
Stephen Brookfield has written extensively about critical reflection and the following is a brief summary of a part of a chapter he wrote in a text on adult and continuing education entitled "The Concept of Critically Reflective Practice."
Brookfield outlines Four Traditions of Criticality found in different fields:
Ideology critique
It is based on a premise that uncritically accepted and unjust dominant ideologies are embedded in everyday situation and practices. The purpose of ideology critique is to examine these assumptions in order to effect change at the social and institutional level. An example of this kind of approach to learning is found in the work of American popular educator Myles Horton. As the founder of Highlander Folk School, during the civil rights movement he started literacy program for African Americans. Study groups would learn to read while engaging in ideology critique in their own lives and communities using the Universal Declaration of Human Rights as a the text.
Psychoanalytic and psycho therapeutically inclined critique
These are traditions that work on identifying and reappraising limitations created through childhood traumas. This tradition advocates individual and group therapy for personal learning and development for the purpose of integration of all aspects of self.
Analytic philosophy and logic
This is the tradition that for most is closely associated to critical reflection. Here critical reflection means to recognize logical fallacies and see the difference between bias and fact and opinion and evidence, and become effective at using different forms of reasoning.
Pragmatic Constructivism
This tradition is based on the premise that reality is perceived, that is, we construct our own meaning out of experiences. The focus here is how people interpret their experience v.s. universal and recognizable truths. There is also a strong emphasis on creating new realities together.
Brookfield proposes that to engage in reflection is not the same as engaging in critical reflection. His understanding of critical reflection is centered on ideology critique rooted in the pragmatic constructivist approach. Renowned Brazilian educator Paulo Friere speaks of a similar process by which adults "achieve a deepening awareness of both the sociocultural reality which shapes their lives and... their capacity to transform that reality through action." Ideology critique is rarely used in the work place. For the most part a culture of conformity and obedience is promoted by organizations.
Brookfield presents a picture of what the process may look like: "The adult educator's task is that of helping people articulate their experience in dialogic circles and then encouraging them to review this through the multiple lenses provided by colleagues in the circle. On the basis of these collaborative critical reflections on experience adults reenter the work to take critically informed actions that are then brought back to the circle for further critical analysis."
To engage in collaborative critical reflection based on a rhythm of action and reflection is not only a process of building collective knowledge and consensus, but also strong foundations for both trans formative learning in the work place and thriving self-organized teams. It is also a way to discover appropriate forms of metrics because it helps people apply multiple lenses of analysis to their work.
Critical reflection should be taught to teams through modeling. For example the coach disclosing his/her won process of critical reflection. Critical reflection should no be associated with self berating and putting others down or the culture of "telling it like it is" without regard for others.
Try the list of questions in the extended text to get a sense of how your work as an Agile practitioner (or whatever work you do) can be enhanced by critical reflection.

Agile Work Uses Lean Thinking - Empirical Process Control
This is Part 2 of a 3 part series.
Part 1
Part 3 - not posted yet :-)
Some work processes cannot be perfectly controlled nor perfectly defined. There may be non-linear interactions between steps in a process or there may be creative input from a human required. Processes with these qualities require empirical process control.
The basic attribute of empirical process control constitutes a continuous cycle of inspecting the process for correct operation and results and adapting the process as needed. A simple example of this is detecting impending failure of equipment by constantly monitoring the operation of that equipment. For Agile Work, the book Agile Software Development with Scrum provides an excellent chapter about this topic of Empirical Process Control.
In human processes like those to which Agile Work applies, the frequency of inspecting and adapting must match the needs of the process. Many projects occur in the context of constant change. This constant change makes long-term planning a wasteful effort. Rather, short-term planning with constant feedback provides a simple inspect and adapt cycle. This cycle can play out at different levels: daily for a team, monthly for a client of the team. The team inspects and adapts daily at the level of the tasks that it is performing. The client inspects and adapts monthly at the level of the team's actual delivered results.
Both lean and agile methods claim to increase both speed and quality. Many people believe that there are four constraints in a system that can be controlled: speed (or schedule, or time to market, or process cycle time), quality (number of defects), scope (how much functionality), and cost savings (how much to spend on the work). Frequently, management believes that one has to trade off between these four constraints; spend more money, get more scope; lower quality, go faster. But in fact, lean and agile strongly support the idea that as you increase quality, you also increase speed... you just have to do it right.
In Agile Work, increasing speed and quality is done in three ways. First, increase the frequency and quality of communication among team members so that errors are detected early or avoided altogether. Second, drive the work with the creation and execution of automated testing. No work is done without a test in place to check if it is done correctly. This constant testing means that work is always defect-free and therefore very little time/money is spent on fixing defects. Third, eliminate wasteful work steps or obstacles to performance of work. This last one is difficult to do an bears closer examination.
Wasteful work is done in every process, no matter how efficient. Lean tells us that there are several types of waste in a manufacturing process. Those types of waste have analogies in Agile Work. For example, documenting something you plan to do instead of just doing it is wasteful. Another example is waiting while someone completes work that you depend upon. Any step or task that does not add value to the final product of an effort is waste. This standard is very high and most organizations have about 80% of their efforts going into wasteful tasks. An organization that has done an initial cut of wasteful work might stand at about 50% waste. The leanest organizations, such as Toyota, stand at about 20% waste.
Agile work eliminates waste in the form of barriers or obstacles that come up when a team is trying to go fast. Sometimes this is in the form of waiting for another group to do something for the agile team... an outsourced request for service. Sometimes waste is in the form of corporate standards or policies around documentation of work. The Process Facilitator role in an agile team has responsibility for working with the team and others to help overcome these obstacles.

Is There a Single "Most Important" Agile Work Practice?
There are a few times that I have been involved with implementing agile pratices without management knowledge or direct support. In these cases it has usually been necessary to gradually introduce the practices. An unsupportive or apathetic environment cannot be changed instantly and big-bang introduction of agile tends to bring too much negative attention too quickly.
In reflecting on those experiences, as well as "normal" agile implementations, I have felt that there are some specific practices that can stand alone.
Self-Organizing Teams
The practice of a self-organizing team consists of frequent regular status meetings, face-to-face, reporting to the other team members accomplishments, work commitments and obstacles. Scrum has a very strict method of doing this on a daily basis but I have found it valuable to do more or less frequently depending on the team and its environment (generally any less than every second day is not enough). The team, or some assistant of some sort, tracks the barriers and works to resolve them quickly. Management, if it exists, must be contacted through trusted channels to assist with the removal of barriers. And stakeholders must be able to attend the status meetings or receive reports immediately after the meetings.
This single practice tends to have the ability to bootstrap the others. The identification and clearing of barriers provides a way for the team to practice all three Agile Work Disciplines (Empower the Team, Amplify Learning, Eliminate Waste). Reporting accomplishments to the other team members Amplifies Learning. Committing to work is empowering.
Some teams have done only this single agile practice and seen great improvements in productivity, morale, and stakeholder satisfaction. However, there are some pitfalls that must be acknowledged and dealt with.
Pitfall: Speculative Work
The team can tend towards speculative work if there is no strong representative of the stakeholders. This does not always happen since most people are sincere in their desire to "make a difference". However, if as a team you adopt only this practice and find yourselves doing lots of "what-if?" or "wouldn't it be neet if..." or "what exactly is our purpose?" discussions, then you need to find some external stakeholder support for your effort.
Pitfall: Failing to Deliver
In many organizations, failure to deliver is an endemic problem and a self-organizing team will break through and start delivering. However, failure to deliver can also become a cultural mindset for an organization or group. A self-organizing team must maintain a goal (not a plan) for itself, and that goal must include delivering something valuable. Again, finding an external stakeholder to support the team's efforts can help to avoid this pitfall.
Pitfall: No Barriers
Sometimes a team will get into a habit where no new barriers are being exposed. This can often happen when the progress in the work becomes steady and is recognizably better than it was before. The team falls into a "local optimum". In this case, the team needs a fresh way to view their work. This can happen in a number of ways: a crisis, an external observer, or a change in environment among others.
...
Do you have experience with successful but incomplete agile implementations? I would love to hear of other experiences and opinions about this.

Agile, the Adult Educator and Ethical Considerations
A review of Tara J. Fenwick's “Limits of the Learning Organization: A Critical Look” (article found in Learning for life: Canadian readings in adult education
This article is a critique of learning organization literature (as presented in the works of Peters, Senge, Watkins, Marsick, Argyris, Schon and others). I chose to do a review of it because learning organization literature can and does inform the work of Agile practitioners. The writer, Tara Fenwick, offers a critique of this literature as an academic and practitioner in the field of adult education. Even though the language and tone of the article is judgmental and at times affronting to the corporate trainer audience, it is never-the-less challenging and valuable because she raises interesting ethical questions that can serve as cautions against potential trends that can distort agile practice. I will summarize her argument in the some of the areas most relevant to Agile practice.
Fenwick's summary of the model of learning organization found in the literature, is an organization that: “creates continuous learning opportunities, promotes inquiry and dialog, encourages collaboration and team learning, establishes systems to capture and share learning, empowers people toward collective vision and connects the organization to its environment.”
The following is a summary list of some of Fenwick's critiques:
Who's Interests are Served
Although the learning organization literature holds great promise for a more humanitarian and egalitarian workplace, it has the potential to distort learning “into a tool for competitive advantage” and in turn, exploit people as resources in the pursuit of profit. To explore this idea she asks a valuable question: “Who's interests are being served by the concept of learning organization, and what relations of power does it help to secure?” She argues that learning organization literature tends to serve the interests of educators working as trainers in organizations and managers interested in their own self preservation.
How Learning is Defined
Learning, in learning organization literature seems to be defined as that which benefits the organization, all other learning falls into the dysfunctional category. This perspective negates other ways that people create meaning and learn and potentially causes a person to become “alienated from their own meaning and block flourishing of this learning into something to benefit the community.”
Assumptions about Learners
The learning organization literature subordinates employees by seeing them as “undifferentiated learners-in-deficit”. Educators and managers are the architects of the learning organization while employees are busy “learning more, learning better and faster” trying to correct their knowledge deficit. In the learning organization workers become responsible for the health of the organization without the authority to determine alternative ways to reach that health. The fear of being left behind in a quickly changing market environment is used to create anxiety and fear as motivations for learning. All of these factors serve to put serious limits on the potential of people to learn in the work environment.
Diversity and Privilege Overlooked
Perspectives of race, class and gender -which research has shown affects the way people learn and collaborate- are lacking in the literature. Fenwick challenges the notion of achieving a democratically ideal situation for open dialog -that the learning organization literature calls for- when all people in the work place do not “have equal opportunity to participate, reflect, and refute one another” (for example because of the status of ones job, character, gender, class, age etc.)
Fenwick sheds a clear light on where the good philosophies of the learning organization are found wanting. The Agile community can benefit from asking some of the same ethical questions she asks in relation to our work. Her critique is a good challenge for Agile practitioners. It challenges us to:
- Continue to strive for higher levels of ethical excellence in our work
- To consider issues of power in our work
- To become conscious of how we use our own power
- To give thought to what voices are included / excluded in the creation of the learning organization
- Pay attention to how we motivate learners
- How to foster collaborative environments that are conscious of the privileging of some over others
- Think about who decides what is valuable knowledge and learning and how that affects the knowledge creation process
Reflecting on these issues will go a long way to contributing to the development of agile practice.
The full text of an old version of Fenwick's article can be found here.

Agile Coach/Mentor Job Description (Process Facilitator)
Given the Agile Axioms and Disciplines then an agile coach or mentor should have some really specific experience and capabilities. This list constitutes a first attempt at a job description.
Experience:
- working in strictly timeboxed iterations with adaptive planning using some sort of prioritized work list
- working in a "test-driven" manner (e.g. writing a document for a client where the client specifies acceptance criteria)
- participating in frequent status meetings where the team members report to each other, commit to work and identify barriers
- building and maintaining big visible charts to show progress and status (e.g. the standard thermometer chart to show progress towards a numerical goal)
- fashioning appropriate tracking and performance metrics that encourage team work rather than individual competition
- helping other people to adopt and adapt all these practices
Capabilities:
- promoting collaboration in challenging circumstances
- searching for truth/a solution relentlessly
- honesty and trustworthiness
- a learning attitude (proactive and learning from mistakes)
- humility and assertiveness
- guiding people without controlling them
- detachment (ability to step out of a situation)
- an attitude of service without expecting recompense
- understanding of transformative learning
- conflict resolution as learning (not negotiation)
- encouraging creativity
Not Required:- technical experience related to the work of the team - the Agile Coach (process facilitator) should not be a performer on the team
- domain experience related to the goal of the work - the Agile Coach should not be a direct stakeholder in the results of the work
However, technical experience and domain experience can sometimes help...
Suggestions and ideas are greatly appreciated!

Tools Versus Capabilities Approach To Agile Training
Which approach is most valuable in training that fosters collaborative work for the purpose of optimizing the performance of an organization: a tools / methodologies approach or an inner capabilities approach? The typical orientation that most organizations take is often external and rule-based. This consists of creating methodologies, rules, boundaries, systems and processes to enhance collaboration.
These external approaches ultimately fail to have a lasting effect on people and the culture of the organization because they don't address change at the level of habits of mind. People then work in the new structure with the same patterns of behaviour. Behind this kind of surface approach to change are assumptions about human nature. At worst this consists of a belief that people are base (greedy, selfish etc.) by nature. At best that people are fundamentally good but cannot improve except through external measures. It is true that we need external systems and structures to give expression to our inner capabilities, to test, foster and develop them in action. However all the investment that companies make in tools, systems, methodologies are obviously not enough. We need both external and internal approaches to training people in collaborative processes. Systems and tools provide only a framework that then need to be filled in with character. At the core of Agile there are disciplines (such as Empower the Team, Amplifly Learning) without which the methodologies would have no life. The practice of the disciplines fostered by the development of inner capabilities infuses life into the Agile methods and at the same time the methods act on and reinforce the inner practice of the disciplines.
As Agile champions (coaches, facilitators, practitioners) we must invest energy on fostering -through modelling and coaching- the development of inner capabilities. The Agile community will benefit from an identification of core capabilities required and a deep exploration of how to foster their development in individuals, teams and organizations.
Although it is our nature to organize in groups and we may have much experience with collaboration, we nevertheless live in a culture of contest and individualism. Out of this culture comes a set of belief systems which are so deeply rooted in our lives that we are not fully conscious of them and their affect on us. These belief systems cannot change easily through the introduction of external structures alone.

The Qualities of an Ideal Test
These six qualities of tests describe how to make a test as effective and as useful as possible. The qualities are similar in style to the INVEST qualities of user stories - but they don't form a nice acronym.
Decisive: The test contains all the information required to automatically determine success or failure. Manual inspection of test results is not necessary to determine success or failure. The test is expressed in a way that produces a pass/fail answer rather than a numerical or qualitative result. Decisive tests are often expressed as assertions.
Valid: The test produces a result that matches the intention for the work artifact under test. Test failure indicates failure in the artifact under test and test success indicates correct operation or configuration of the artifact under test. Simply put: the result of a test should be true.
Complete: The test contains all the information it needs to run correctly with a given test harness and work artifact under test. The test performs all activities and provides all the data necessary. The test does not require any input outside of itself in order to run.
Repeatable: The test always gives the same results if the test harness and the artifact under test are the same. The test is created in such a way that the result is deterministic. Even if the system under test is not deterministic, the test should be created to account for that (possibly with statistical analysis) and produce a deterministic result.
Isolated: The test result is not affected by other tests run before it nor does a test affect the results of tests run after it. The test and the test harness work together to clean up after every test is run. A collection of tests can be run in any order and always produce the same results. Any test that depends upon the results or side-effects of a previous test is not isolated.
Automated: The test requires only a start signal in order to run to completion in a finite amount of time. No manual intervention is required after the test is started. Tests that are automated can be put together into a test suite and run one after another without human intervention. Automation of tests requires the creation of a test harness system.
Update 20060106
I've added a little bit more detail to the above qualities. I also wanted to say a few words about my experience with testing:
I first started doing test-driven development almost seven years ago after reading the book Refactoring by Martin Fowler. I picked it up in Windsor Ontario while I was driving to San Francisco for my first contract position as an independent. I had to stay the night there due to the immigration office being closed so I read a lot of the book in my motel room that night. By time I got to California four days later, I was totally convinced that I should be using JUnit and refactoring for everything I did. Fortunately my project was ammenable to this approach. Over the next four months I built a Java JMS layer on top of Tibco Rendezvous. In the process I discovered methods for doing unit tests for asynchronous multi-threaded distributed functionality. And my tests satisfied all the above qualities. I delivered code with 100% test coverage and zero defects discovered until more than two years later when a very rare and obscure deadlock issue was found. Suffice it to say, I was convinced from a quality perspective.
But there is more. To build tests that follow all the above qualities, you need code that is testable. I have come to believe that testability is the most important architectural attribute of code for most software. The implications of having testable code include code that is easily changed, that is verifiable, and that is easy to understand. Refactoring plays a big role here too.
For getting a basic but very practical sense of test driven development, I strongly recomment Test Driven Development: By Example 
I have also written a couple of articles recently about quality:
Quality is Not Negotiable in which I talk about how to handle defects - by always treating them as top priority work items.
and
Technical Debt in which I expand on this common analogy between lack of testing and debt to show that technical debt is even worse than financial debt.

Amplify Learning
Learning is the result of both encountering new experiences and deliberate experimentation. Learning creates new knowledge, increased volition and improved action.
Some of people's best learning comes from “failure”. An essential component of learning is feedback.
Learning and feedback can be amplified in several ways. Provide opportunities for learning through books, training courses, coaching, deliberate exposure to diverse work, and deliberate experimentation. Frequently ask the questions “why?” and “how?” and answer the honestly and deeply. Increase the level and quality of communication among the stakeholders and team members. Inspect work in progress frequently or even continuously. Learning accelerates greatly if a culture of learning is created where individuals feel free to experiment and take initiative even on critical aspects of the work.
Learning and feedback support all three agile principles. People become more effective creators as they learn. People are better able to adapt to and embrace change as they learn. And a person's span of perception increases as they learn. Any increase in learning or feedback leads to an increase in the manifestation of the principles.
Learning and feedback can be amplified rapidly, but an empowered team is necessary to effectively take advantage of this amplification. If a team is not empowered, then rapid learning can lead to frustration. Amplified learning and feedback result in excitement, enthusiasm and playfulness, rapid problem solving, high quality work results and satisfied stakeholders.
An excellent analysis of learning at a social or group level is presented in Progress and Its Problems by Larry Laudan. In this very well written book, Laudan takes a look at the history and philosophy of science and develops a model for learning that is applicable to the development of agile methods.

Empower the Team
Empowerment is the ability of a team to make decisions about how to do their work and execute on those decisions without outside interference. If a team is empowered, then it will be more capable of responding to change, and it will be able to focus on manifesting the members' creative potential. Empowerment comes from a combination of several factors:
1. members of the team have a deep sense of self-worth that includes nobility, and contribution to the progress of humanity
2. tacit or explicit authority and responsibility for results as a team and as individuals
3. a team environment which is honest, trusting and allows for mistakes
4. the absence of personal attacks against individuals on the team and in particular a total lack of gossip and backbiting
There are several ways that team members will demonstrate their empowerment. People will derive joy from their work. Team members will be dedicated to the work and the team. Individuals on the team will frequently take individual initiative to accomplish tasks, share insights, and develop improvements. Spontaneous leadership will become common. Individuals will step out of comfort zones or areas of specialization in order to assist the team.
Empowering a team is a process that can sometimes take a great deal of time and effort. In order to start on this process, the team members should carefully listen to each other and ask many questions. More mature individuals should lead and teach by example. And all the team members can start to question and challenge the rules and procedures of an environment that are preventing effective work. If the team is in an organizational environment where team members have management to report to, then management must be aware of this opportunity for empowerment and support it.
An empowered team can gradually understand and internalize the agile work principles (People are Creators, Change is Constant, Perception mediates Reality). By internalizing these principles, a team can move beyond specific agile work practices and become a high performing team setting their own work practices.
Jeff Sutherland has a very brief blurb about the progress of teams as they evolve in their use of Scrum.
Future entries here will discuss the methods of creating empowered teams.

Book Review: "Good to Great" by Jim Collins
Summary: In this well-written, engaging book, author Jim Collins describes six critical factors that he and his research team found common in companies that transformed themselves from a long period of mediocre or bad results to a long period of great financial results. Although focused on publicly-traded companies in the United States, the results of this research can easily be extended to apply to other types of organizations.
Good to Great describes the following six concepts:
- Level 5 Leadership: personal humilty and professional discipline in an organization's leader are the starting point for the transformation.
- First Who... Then What: don't worry about what to do until the right people are in the right positions in an organization.
- Confront the Brutal Facts (Yet Never Lose Faith): careful and honest examination of an organization's current situation is the foundation for finding a path forward.
- The Hedgehog Concept (Simplicity within the Three Circles): discover a simple business concept that people can be passionate about, that works with a single key economic driver and that the organization can be the best in the world.
- A Culture of Discipline: disciplined people removes the need for heirarchy, disciplined thought removes the need for bureaucracy and disciplined action removes the need for excessive controls.
- Technology Accelerators: pioneer the application of carefully selected technologies without relying on technology for transformation.
Some of these concepts are very close to the underlying prinicples of agile work. For example, in the Scrum methodology, the first five principles are all represented. The Scrum Master embodies some of the attributes of level 5 leadership. A self-organizing team gets the right people in the right position. The daily scrum and the sprint planning meetings are designed to help the team confront the brutal facts. The sprint goal embodies at a local level the simplicity of the hedgehog concept. And the practices in general are a manifestation of a culture of discipline.
Who Should Read this Book? Anyone interested in creating a lasting positive transformation in an organization should read this book. In particular, individuals who are coaching teams or organizations should read this book since the concepts also appear to apply at a sub-organizational level.

Agile Household Management
Four weeks ago my wife, Melanie, reviewed a paper I was writing about Agile Work. When I talked to her about it, she asked me why we aren't using these practices for managing our household.
So, we decided to try it. First we developed a starting Work Queue. It includes stuff like "eye appointment for Mishkin" and "build boxes for vegetable garden" and "set up expenditures spreadsheet". It covers any activity that is non-repeating, non-business. Things we need to do with the kids, renovations, travel plans, personal finances, community work, social events.
Once we developed our Work Queue, we agreed that Melanie would be the Queue Master, responsible for managing the work and prioritizing it. So, with a small amount of coaching, she prioritized our rather long list of Work Queue items.
We then jointly decided how much to accomplish over the next week. Our iteration length is one week because we already have a natural rhythm of that length due to my travel schedule for work. We took on about 15 items from the queue, and committed to getting them done.
We have now been doing this for a little more than three weeks. Having this process in place has been helpful in a number of ways. First of all, because it is in priority order, our level of stress about what we need to do is decreasing rapidly. Secondly, we are starting to develop a sense of how much work we can accomplish in a one-week period. By being focused, I am finding that we can get more done than I would otherwise expect. Thirdly, by working in weekly iterations, we can quickly adjust to things that come up. Finally, we have a clear set of expectations about what we will accomplish and this reduces feelings of tension around household work.
There are some things that I would like to add to our approach. We have three young children and I would like them to become involved with the process. The eldest is nearly seven, reads at least three years ahead of his age, and is certainly capable of understanding the text-based format of our planning. I would also like to see how we can incorporate acceptance test-driven work into the mix. Because we are such a small team this may be overkill, but at this point we are not explicitly checking our work at all or setting any sort of acceptance criteria. I can see that jumping up to bite us in the future.
I would be interested in hearing from anyone else who has tried applying agile techniques and practices in their own households.
