Technical Push-Back – When is it Okay? When is it Bad?

Whenever I run a Certified Scrum Product Owner training session, one concept stands out as critical for participants: the relationship of the Product Owner to the technical demands of the work being done by the Scrum team.

The Product Owner is responsible for prioritizing the Product Backlog. This responsibility is, of course, also matched by their authority to do so. When the Product Owner collaborates with the team in the process of prioritization, there may be ways which the team “pushes back”. There are two possible reasons for push-back. One is good, one is bad.

Bad Technical Push-Back

BudapestDSCN3928-smallThe team may look at a product backlog item or a user story and say “O gosh! There’s a lot there to think about! We have to build this fully-architected infrastructure before we can implement that story.” This is old waterfall thinking. It is bad. The team should always be thinking (and doing) YAGNI and KISS. Technical challenges should be solved in the simplest responsible way. Features should be implemented with the simplest technical solution that actually works.

As a Product Owner, one technique that you can use to help teams with this is that when the team asks questions, that you aggressively keep the user story as simple as possible. The questions that are asked may lead to the creation of new stories, or splitting the existing story. Here is an example…

Suppose the story is “As a job seeker I can post my resume to the web site…” If the technical team makes certain assumptions, they may create a complex system that allows resumes to be uploaded in multiple formats with automatic keyword extraction, and even beyond that, they may anticipate that the code needs to be ready for edge cases like WordPerfect format.  The technical team might also assume that the system needs a database schema that includes users, login credentials, one-to-many relationships with resumes, detailed structures about jobs, organizations, positions, dates, educational institutions, etc. The team might insist that creating a login screen in the UI is an essential prerequisite to allowing a user to upload their resume.  And as for business logic, thy might decide that in order to implement all this, they need some sort of standard intermediate XML format that all resumes will be translated into so that searching features are easier to implement in the future.

It’s all CRAP, bloat and gold-plating.

Because that’s not what the Product Owner asked for.  The thing that’s really difficult for a team of techies to get with Scrum is that software is to be built incrementally.  The very first feature built is built in the simplest responsible way without assuming anything about future features.  In other words, build it like it is the last feature you will build, not the first.  In the Agile Manifesto this is described as:

Simplicity, the art of maximizing the amount of work not done, is essential.

The second feature the team builds should only add exactly what the Product Owner asks for.  Again, as if it was going to be the last feature built.  Every single feature (User Story / Product Backlog Item) is treated the same way.  Whenever the team starts to anticipate the business in any of these three ways, the team is wrong:

  1. Building a feature because the team thinks the Product Owner will want it.
  2. Building a feature because the Product Owner has put it later on the Product Backlog.
  3. Building a technical aspect of the system to support either of the first types of anticipation, even if the team doesn’t actually build the feature they are anticipating.

Okay, but what about architecture?  Fire your architects.  No kidding.¹

Good Technical Push-Back

Rube Goldberg Self Operating Napkin

Sometimes stuff gets non-simple: complicated, messy, hard to understand, hard to change.  This happens despite us techies all being super-smart.  Sometimes, in order to implement a new feature, we have to clean up what is already there.  The Product Owner might ask the Scrum Team to build this Product Backlog Item next and the team says something like: “yes, but it will take twice as long as we initially estimated, because we have to clean things up.”  This can be greatly disappointing for the Product Owner.  But, this is actually the kind of push-back a Product Owner wants.  Why?  In order to avoid destroying your business!  (Yup, that serious.)

This is called “Refactoring” at it is one of the critical Agile Engineering practices.  Martin Fowler wrote a great book about this about 15 years ago.  Refactoring is, simply, improving the design of your system without changing it’s business behaviour.  A simple example is changing a set of 3 radio buttons in the UI to a drop-down box with 3 options… so that later, the Product Owner can add 27 more options.  Refactoring at the level of code is often described as removing duplication.  But some types of refactoring are large: replacing a relational database with a NoSQL database, moving from Java to Python for a significant component of your system, doing a full UX re-design on your web application.  All of these are changes to the technical attributes of your system that are driven by an immediate need to add a new feature (or feature set) that is not supported by the current technology.

The Product Owner has asked for a new feature, now, and the team has decided that in order to build it, the existing system needs refactoring.  To be clear: the team is not anticipating that the Product Owner wants some feature in the future; it’s the very next feature that the team needs to build.

This all relates to another two principles from the Agile Manifesto:

Continuous attention to technical excellence and good design enhances agility.

and

The best architectures, requirements, and designs emerge from self-organizing teams.

In this case, the responsibilities of the team for technical excellence and creating the best system possible override the short-term (and short-sighted) desire of the business to trade off quality in order to get speed.  That trade-off always bites you in the end!  Why? Because of the cost of fixing quality problems increases exponentially as time passes from when they were introduced.

Refactoring is not a bad word.

Keep your code clean.

Let your team keep its code clean.

Oh.  And fire your architects.

¹ I used to be a senior architect reporting directly to the CTO of Charles Schwab.  Effectively, I fired myself and launched an incredibly successful enterprise architecture re-write project… with no up-front architecture plan.  Really… fire your architects.  Everything they do is pure waste and overhead.  Someday I’ll write that article :-)

Theoretical Team Member Allocation Adjustment for Team Capacity Adaptation Projections Game: Adaptive Planning for Adjusted Team Capacity in Scrum

Author’s caveat:

Lots of smart people have already come up with lots of ways of doing adaptive planning, and chances are someone has already come up with some variation of this particular approach. I have not yet had the benefit of reading everything that everyone else has already written about Agile and planning, so this has been generated by my own experiential learning on the ground as an Agile coach.  Sometimes, as a ScrumMaster/Agile Coach, you are called upon to be a two-trick pony.  This is my other trick.

 Requirements for team estimation (and planning):

  • Product Owner
  • The whole Development Team (i.e. everyone who will be involved in doing the work)
  • Product Backlog
  • Definition of “Done”

 When team membership changes:

A Scrum Team that is estimating effort against Product Backlog items for project planning and timeline projections and changes team membership for one or more Sprints must also re-estimate the remaining items (or at least the items that will be part of the Sprints in which the different/additional team members are expected to participate) regardless of estimation method (Agile Planning Poker or otherwise). The people involved in doing the work (Development Team members/Sprint) must also be involved in providing team estimates. The Development Team is responsible for all estimates as a whole team and therefore should provide estimates as a whole team. The Planning Poker game is widely understood by Agile experts and successful Agile teams as the best tool for facilitating team estimation. Part of what makes Planning Poker so effective is that it does not only provide accurate timelines, but it also facilitates knowledge-sharing among team members as everyone on the team is required to endeavor to understand the degree of complexity of the work of all other team members in order to deliver each item according to the team’s Definition of “Done”.

When team member allocation is adjusted:

Sometimes, the Development team will have people partially dedicated to the team. After one or two Sprints, it becomes apparent that full dedication of all Development Team members is required for optimal team performance. As result, management can be assisted to reconsider allocation of team members towards 100% dedication to the work of a single Scrum Team. Increased (or decreased) dedication of team members can also be expected to have a corresponding impact on velocity (effort points completed per Sprint). However, the Scrum Master needs to help the team (and their managers) to be careful to avoid planning against the unknown. Scrum allows a team to adapt based on actual historical data. Therefore, planning against minimum historical velocity is strongly recommended as a general best practice. At the same time, if a team starts off with, say, 50% allocation of team members and management decides to bump it up to 100%, it is fairly safe to assume that you will actually get somewhat more out of the team. How much more is never possible to know, as human beings are reliably incapable of predicting the future. The moderate way to approach this is to plan the next Sprint based on previous velocity, finish the planned work early in the Sprint, get a bunch of “extra” stuff done, then calculate velocity of the new and improved team and plan against the new and improved velocity. This allows the team to adapt to actuals and not be blind-sided by unforeseen impediments/bottlenecks.

Sometimes, there is a need for management to get a sense of how much more velocity the team will get from increased team member allocation in order to feel that an informed decision has been made. There is a simple (though not risk-free) method for doing this that I have whipped up after being put on the spot on several occasions. I have decided to call this the Theoretical Team Member Allocation Adjustment for Team Capacity Adaptation Projections Game.

WARNING:

The purpose of this exercise is to provide decision-makers with a sense of how much they are going to get out of adjusted allocation of team members to Scrum Teams. Scrum Teams perform optimally when all team members are 100% dedicated to the team. This game should be used with caution and as a means to help organizations move closer to 100% dedication of all Scrum Team members (at least all Development Team members) and, therefore, eliminate the need for this game. Great care should be taken to not encourage perpetuation of dysfunctional Waterfall habits such as “we will now go twice as fast and get done twice as early with twice the allocation of resources because we have this shiny new crystal ball called Theoretical Team Member Allocation Adjustment for Team Capacity Adaptation Projections Game that tells us so.” As long as no one believes that this is magic, it is likely safe enough to proceed to Step 1.

Step 1 – What is our current velocity?

After the first Sprint, the team should be able to count up the number of Product Backlog items completed and add up the corresponding number of “Effort Points” established during its initial estimation (Planning Poker) sessions. Let’s say for our example that the number completed for Sprint 1 is 21 Effort Points. Therefore, the current velocity of the team is 21. Let’s say that this is not a comfortable realization for the team because at some point in the past it had been estimated that this project would take the team about 5 Sprints to complete. Now, the team has done 21 points in the first Sprint and the total number of Effort Points on the Product Backlog estimated by the team is just under 210. Uh oh… 10 Sprints! Whoops! Now what do we do?! Are the new estimation values wrong? Should we stick to the 5 weeks and just have everyone work overtime on this project? Should we take this to management? Let’s say that this team decides to take it to management. But what if management needs more information than “team velocity = 21, Product Backlog = 210, therefore it’s going to take us 10 Sprints instead of 5”? Never fear, Theoretical Team Member Allocation Adjustment for Team Capacity Adaptation Projections Game is here!

Step 2 – What is our current capacity?

As part of Sprint Planning, the team needs to have a sense of its capacity in order to create the Sprint Goal and Sprint Backlog. Therefore, the team should already have a sense of its own capacity. Let’s say for our example that the (fictional) Development Team had the following projected allocation for the first Sprint:

50%        Chris P. Codemuncher

50%        Larry Legassifulunch

25%        Beth Breaksidal

40%        Gertrude Gamesthadox

40%        Dana Deadlinedryver

The team is doing 2-week Sprints. After calculating the time that the team has allocated for Scrum Events, the remaining time for doing the work of the Sprint is about 8.5 days. Therefore, we can calculate the total allocated days per team member as such:

8.5 x 50% = 4.25 days    Chris P. Codemuncher

8.5 x 50% = 4.25 days    Larry Legassifulunch

8.5 x 25% = 2.13 days    Beth Breaksidal

8.5 x 40% = 3.4 days      Gertrude Gamesthadox

8.5 x 40% = 3.4 days      Dana Deadlinedryver

17.43                              Total combined available days per Sprint

Let’s round that down to 17. That’s the number used by the team to understand its capacity for Sprint Planning. This is a powerful number for other reasons than what we are trying to get at here, but they are worth pointing out nonetheless. For generating the Sprint Backlog in Sprint Planning, this is particularly useful if each task in the Sprint Backlog is a maximum of a one-person-day. Therefore, this team should have a minimum of 17 tasks in the Sprint Backlog and these tasks should all be a one-person-day or less amount of effort. If the team has more than 17 tasks which are all about a one-person-day of effort, chances are the team has overcommitted and will fail to deliver the Sprint Goal. This should trigger the adaptation of the Sprint Goal. In any case, it provides the team with simple transparency that can easily be inspected and adapted throughout the Sprint. For example, with one-person day tasks, each team member should be able to move at least one task into the “Done” position every day and point to that movement every day during the Daily Scrum. Also, this team should be burning down at least 5 tasks every day. If either of these fails to occur, this is a clear signal for the team to inspect and adapt.

Now, let’s get back to our Theoretical Team Member Allocation Adjustment for Team Capacity Adaptation Projections Game. As a result of Steps 1 & 2 we now know that the team’s velocity is 21 Effort Points and that the team’s capacity is 17 person-days per Sprint. For short, we can say:

21            Velocity

17            Capacity

21/17       V/C

(WARNING: This number is dangerous when in the wrong hands and used as a management metric for team performance)

 Step 3 – How much capacity do we hope to have in the next Sprint?

Let’s say a friendly manager comes along and says “you know what, I want to help you guys get closer to your original wishful thinking of 5 Sprints. Therefore, I’m deciding to allocate more of certain team members’ time to this project. Unfortunately, I can only help you with the ‘developers’, because everyone else reports to other managers. I’m concerned that Beth is going to become a bottleneck, so someone should also speak with her manager. But for now, let’s bump Chris up to 100% and Larry up to 75% and see what that does for you. We’re also going to throw in another ‘specialist developer’ that you need for some stuff in your Product Backlog at 100%. How much more velocity can I get for that?”

Okay. So…more allocation = more capacity = more velocity, right? If we acknowledge that this is highly theoretical, and remember the initial WARNING of the game, we can proceed with caution…

But just as we get started on calculating the adjusted allocation of team members, we find out that Beth was actually more like 50% allocated, Dana was more like 15% allocated and Gertrude was more like 30% allocated. We need to recalculate our actuals for Sprint 1:

8.5 x 50% = 4.25 days    Chris P. Codemuncher

8.5 x 50% = 4.25 days    Larry Legassifulunch

8.5 x 50% = 4.25 days     Beth Breaksidal

8.5 x 30% = 2.55 days     Gertrude Gamesthadox

8.5 x 15% = 1.28 days     Dana Deadlinedryver

16.58                               Total combined ACTUAL available days in Sprint 1

16                                    Actual capacity (rounded-down)

21/16                               Actual V/C

As a side note, Beth had to work on a Saturday in order to increase her capacity but she spoke with her manager and thinks that from now on she will probably be able to maintain this degree of dedication to the team without having to work any more overtime.

Now the team can calculate its hoped-for capacity for Sprint 2 and beyond:

8.5 x 100% = 8.5 days     Sally Supaspeshalis

8.5 x 100% = 8.5 days     Chris P. Codemuncher

8.5 x 75% = 6.38 days     Larry Legassifulunch

8.5 x 50% = 4.25 days     Beth Breaksidal

8.5 x 30% = 2.55 days     Gertrude Gamesthadox

8.5 x 0% = 0 days            Dana Deadlinedryver

(Note: Dana is also the Scrum Master with plenty of other work to do for the team)

30.18                               Total combined hoped-for available days in Sprint 1

30                                     Hoped-for capacity (rounded-down)

Step 4 – How much velocity do we hope to have in the next Sprint?

21            Actual Historical Velocity

16            Actual Historical Capacity

30            Hoped-For Future Capacity

x              Hoped-For Future Velocity

Some simple math, loaded with assumptions:

Actual Historical Velocity/Actual Historical Capacity = Hoped-For Future Velocity/Hoped-For Future Capacity

Therefore if 21/16 = x/30, then x = 21 x 30/16 = 39.375

39            Hoped-For Future Velocity

Step 5 – How do we adapt our planning in light of what we now know (assuming we now know something substantial enough to inform our planning)?

Hopefully, not much. The best thing for the team to do at this point is to plan against its actual historical velocity of 21. If team members finish their work in the Sprint Backlog early, they should help out with other tasks until the Sprint Goal is delivered. Then, if the team achieves the Sprint Goal early and has extra time left before the end of the Sprint, then the team can pull additional items to work on from the Product Backlog. If the velocity of the team actually increases as a result of actual increased capacity, then the team can safely plan against its increased velocity beginning in Sprint 3. However, Hoped-For Future Velocity is often way too tantalizing for a team that already strongly (and to some extent, logically) believes that it can get more done with more capacity. So, most teams will usually plan to do more in light of this knowledge and that’s fine. Scrum allows them to inspect and adapt this plan at least every day. The team will figure it out.

Thank you for playing Theoretical Team Member Allocation Adjustment for Team Capacity Adaptation Projections Game. I hope it was as fun to play as it was to create!

Full-Day Product Owner Simulation Exercise

This simulation exercise rests on the idea that people learn a lot better by doing something than by talking about it.  My Product Owner classes were getting great reviews, but I really felt like there was something missing compared to my ScrumMaster classes which have a full-day ScrumMaster simulation exercise.  It took a little while to figure it out, but this article describes in detail how I do the simulation for the Product Owner class.  I’m sure it will evolve and get refined from here since I have only used the simulation twice so far.

NOTE: Permission to use this exercise / print associated materials is granted with a simple request: please link to this page on your blog, in a LinkedIn group or Google group, like it on Facebook etc. or write a comment in our comments section!

Pre-requisites: None!  No prior Scrum or Agile knowledge or experience required.

Audience: Product Owners, Business Analysts, Project Managers, Product Managers and other people responsible for business results and who interact with a Scrum team.

Timing: This simulation takes at least 7 classroom hours.  I usually run it from 8:30am to 5:00pm with a one hour lunch break and two 15 minute breaks during the day.

Materials Needed:

  • Coloured pencils and/or coloured markers
  • Black Sharpie fine-point markers
  • Scissors
  • Rulers
  • Scotch tape and/or glue stick
  • Blank white printer paper
  • Pencils, erasers, pencil sharpeners
  • Blank white 4×6 and 3×5 note cards
  • Blank white box (e.g. a shirt box from U-Line)
  • Planning Game cards (email me if you want a bunch for free!)

Room Setup: Round tables with 4 to 6 chairs at each table.  Materials distributed to each table.

Agenda (with facilitator’s notes):

  • Lecture: Simulation Overview, Backlog Preparation and Refinement
    The purpose of the overall simulation is to learn to create a good Product Backlog in preparation for a Scrum team’s first Sprint. Review the agenda with participants.
  • Discussion: Choosing a Product for the Simulation
    Give participants four product options (suggested options: “Doggy dating web site”, “iPad app for plastic surgeons”, “POS for food trucks with social features”, or come up with your own app idea).  A table group must agree to one of the options.  They will stick with this product for the remainder of the simulation.  5 minutes to decide (usually takes much less).
  • Part 1: Product Vision
    • Lecture: Innovation Games – Product Box
      Talk about the need for a compelling vision as a pre-requisite for high-performance teams, and a way to decide what is in vs. out of a Product Backlog.  Introduce “Product Box” as a way to do market research in an Agile compatible way (collaborative, light documentation, quick).  Talk about the pattern of a product box: front to attract, back to showcase, sides to deal with objections.  Use of online resources / web research is allowed but should not dominate the exercise.
    • Exercise: Building Your Product
      30 minutes, with warnings at 15 minutes and 5 minutes remaining.  Ensure that by 10 minutes in, the group has actually started using the craft supplies and isn’t just talking.
    • Exercise: Presenting Your Product
      5 minutes – give additional time to allow groups to prepare for a trade show (in their market) presentation where other groups (or yourself) will role-play sceptical trade show participants.
    • Discussion: Debrief
  • Part 2: Product Users
    • Lecture: User Categories
      Describe “end users”, “customers” and “admin users” as the three major categories.  Users can be in hierarchies where a general user type may have two or more specific sub-types.
    • Exercise: Identifying Users
      10 minutes.  One user of each main type (end, admin and cust), at least 5 users in total.  More is okay.
    • Lecture: Personas, Usability and Empathy
      Introduce Persona concept (great reference: “The Inmates are Running the Asylum” by Alan Cooper).  Usability as part of Agile, not separate (i.e. “working software”).  Identifying personas as a way to build empathy from the development team to the end users/customers.
  • Part 3: User Stories
    • Handout: User Stories and Splitting
    • Lecture: Writing Effective User Stories
      Use the example “As a Job Seeker, I can upload my resume, so that I get a job.”  Explain the user story template based on the handout.  Emphasize the idea of end user functionality.  Explain user stories as an important tool, but optional part of Scrum.
    • Exercise: Create User Stories
      Goal: 20 user stories for each group’s product, at least two user stories for each type of user, all done in 20 minutes.  User Stories must be written on 3×5 note cards with a 2cm blank area on right side of each card.
    • Discussion: Review User Stories
      Workshop examples from each group.  Ensure that the “benefit” section of each story does not contain a feature.
    • Lecture: Splitting User Stories
      Go through each of the “top” six splitting methods.  Provide simple examples where the group needs help.  E.g. error conditions as an example of splitting by business logic.
    • Exercise: Split Some
      Goal: result in at least 30 user stories, use each of the top six splitting methods at least once, give 15 minutes.
    • Discussion: Review Splitting
  • Part 4: Estimation and Financial Modelling
    • Lecture: Effort, Value and ROI
      Customers and business stakeholders estimate value, Scrum team members estimate effort, and ROI is the calculation of the ration of value over effort.  Discuss examples of ordering based on these ratios, e.g. 8/2 vs. 8/4 and 200/20 vs. 20/2.
    • Handout: The Bucket System
    • Lecture: The Bucket System
      Review process based on handout.
    • Exercise: Estimating Business Value
      10 minutes.  Goal: all user stories get a business value estimate written in the top right-hand corner of the user story card.
    • Discussion: Debrief the Bucket System
    • Handout: The Planning Game
    • Lecture: The Planning Game
    • Exercise: Estimating Effort
      20 minutes. Goal: estimate 3 user stories using the Planning Game.  Use the Bucket System to estimate the remainder with the ones already estimated as the reference points.
    • Discussion: Debrief the Planning Game
    • Handout: Methods of Ordering the Product Backlog
    • Lecture: Ordering a Product Backlog
      Review ROI as a method to order the PBIs.  Reminder that the Product Owner has final authority and can ignore the estimates in deciding on the order.
    • Exercise: Calculating ROI and Ordering
      5 minutes.  Just simple divide-and-conquer calculations of business value divided by effort for all the user stories.
    • Lecture: Simulation Wrap-Up – Where Does This Fit?
      Reminder of the idea of creating an initial Product Backlog that is “good enough” to start the first Sprint.

NOTE: Permission to use this exercise / print associated materials is granted with a simple request: please link to this page on your blog, in a LinkedIn group or Google group, like it on Facebook etc. or write a comment in our comments section!

The Agile Framework: Agile Values and Principles, The Agile Toolkit, The Agile Organization

When I am speaking with executives, ScrumMasters and other leaders of change in organizations, I often present a simple 3-layer model to understand the relationship between the various moving parts in the Agile Framework:

  1. The Agile Values and Principles – These describe the culture and, in the Agile Manifesto, are the definition of the word “Agile” as applied to software development. I didn’t write the Agile Manifesto so I don’t get to re-define the word Agile.  To give an example: in the manifesto it says “The best architectures, requirements and designs emerge out of self-organizing teams.”  As a former enterprise architect at Charles Schwab, I struggled with what I saw as incredibly wasteful up-front architectural activities when I knew that developers would (sometimes) ignore my glorious ivory-tower plans!  Therefore, if you are still doing up-front architecture and forcing your teams to comply to that architecture, you aren’t Agile.  Therefore, as an individual, a team or an organization, you need to make a conscious decision to “BE” Agile or not… and if you decide not, then please don’t call yourselves Agile.
  2. The Agile Toolkit – There are many hundreds of distinct tools in the Agile toolkit including Scrum, OpenAgile and other “large” Agile methods, as well as the Planning Game, Product Box, Test-Driven Development and other “small” Agile techniques.  Any group of people trying to BE Agile, will need to use dozens or even hundreds of different Agile tools.  I call them tools because the analogy with construction tools is a very good one.  Scrum is like a hammer.  But you can’t do much with just a hammer.  Scrum is a great, simple tool.  But you always need other tools as well to actually get stuff done.  All the tools in the Agile Toolkit are compatible with the Agile Values and Principles.  Even so, it is possible to use the Agile Tools without being Agile.  A Scrum team that never gets together face-to-face is not an Agile team: “The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.”  (Video conferencing doesn’t count.)
  3. The Agile Organization – When you start using a tool, there is a learning period.  We start by being conscious of our incompetence and as we persist, we become competent… but it isn’t natural or habitual yet.  Eventually, with continued use, we become unconscious of the tool.  IDE’s and version control are like this in most organizations: we don’t even think about them!  But getting through that initial stage requires us to change; to develop new skills.  This process usually requires discomfort or pain (including psychological pain).  An organization attempting to BE Agile and to use many of the tools in the Agile Toolkit will need to make many changes and often these will be difficult.  For example, incorporating the Product Owner role from Scrum into your organization requires new role definitions, new performance evaluation practices and criteria, new compensation systems, new communication and reporting mechanisms, new authority and accountability processes, etc. etc.  All of the changes required are about creating Enterprise Agility throughout the whole organization, beyond just software or IT.  These extensive changes are often started in a very ad hoc manner, but at some point they need to become systematic.  This is an important decision point for executive management: are we going to be Pragmatic about our Enterprise Agile adoption, or are we going to be Transformative about our Enterprise Agile adoption.

All of this is summarized in this graphic:

Re-launch of Real Agility Newsletter

Hi Everyone!  Berteig Consulting is going to re-launch their monthly newsletter starting this month!  We’re excited about it because, although it is partly due to a legal change around commercial email here in Canada, we are considering this a great opportunity to change the style of our communication with our customers and our colleagues.  Like before, we plan to have a few regular segments:

  1. A message from me, Mishkin Berteig, that shares my personal experiences with Agile, with running an Agile consultancy, and other things that I hope will be interesting.
  2. A “Coaching Corner” article written by one of our coaches, or by a guest author, about how organizations, teams and people can become more Agile.  Topics will range from technical to people-oriented, practical to theoretical, cutting-edge to deeply retrospective.  We hope these articles will become a great resource – and they won’t be cross-posted here on Agile Advice.
  3. A listing of our upcoming training.  We’re excited that in the fall and in the new year we are going to start offering some things besides just ScrumMaster and Product Owner training including training on Agile Coaching, SAFe (and maybe even other enterprise agile frameworks), and topics closely related to Agile such as leadership, communication, etc.
  4. And of course, a “special offers” section that will promote new products or services from us or from close partners that we think will be helpful.

Please subscribe to our Real Agility Newsletter by clicking on the link:

The Three Fundamental Principles of Agile Estimation – The Third One Will Surprise You!

You probably already use an Agile Estimation technique such as the Planning Game or the Bucket System, but surprisingly few people understand the underlying principles of Agile Estimation.  This lack of understanding often causes confusion or stress for the people who try to use Agile Estimation techniques.  The discrepancy between traditional estimation techniques and Agile techniques is large and it is hard to bridge that mental gap without understanding the principles involved.  There are three fundamental principles of Agile estimation:

Principle One: Collaborative

Agile estimation methods are collaborative.  This means that multiple people work together to arrive at estimates for work in an Agile project or product development effort.  Traditional estimation techniques (such as those related to bottom-up or top-down) tend to focus on individuals estimating the work that they are responsible for doing and “trusting” those individual estimates.  Collaborative estimation means that most estimation is done by people in formally facilitated meetings where people are present in-person.

Collaborative techniques are generally used where there is some expectation that multiple minds are better than a single mind in discovering some new knowledge or solving a problem.  Teamwork and groupwork are based on this concept.  This idea of collaboration for problem solving is also applied to Agile Estimation and it has some interesting ramifications.

The most radical consequence of collaborative estimation methods is that there is no possibility to trace a particular estimate for a particular item to a particular individual person.  This lack of traceability is important to create a sense of safety on the part of participants in the estimation effort.  This safety is necessary to allow participants to be fully honest about estimates even if those estimates conflict with expectations of powerful stakeholders.  Another way of stating this principle is that no individual can be punished for a bad estimate.

Many Agile estimation techniques take this principle beyond just mere collaboration to the level of consensus-building techniques where everyone in a group doing estimation work must agree on the final estimate for each and every item being estimated.  This strengthens the idea of safety to the point where no participant in an estimation effort can ever say “I didn’t agree with that” and thereby leave other participants “on the hook” for a bad estimate.

Principle Two: Relative Estimation

Imagine you are shown a glass bottle with some water in it.  You can see the water sloshing around.  Someone asks you, “how much water is in the bottle?”  You might, at first, think about the overall size of the bottle and respond by saying “it’s 1/3 full.”  Or, if asked to provide a measure in units like millilitres or fluid ounces, you might mentally compare what you see in front of you to some container (e.g. a measuring cup) where you know the quantity.  In both cases, you are doing a relative estimate of the amount of water in the bottle.  You are comparing the amount of water to a known quantity.

Imagine a counter-example: someone walks up to you with a red pen ask asks you “what is the wavelength of the light being reflected from this red ink?”  If you are like most people, you have probably forgotten (if you ever knew) the wavelengths of light in the visible spectrum.  You have no basis for comparison.  You might take a wild guess, but it is just that.  Going back to our relative measure, you might be able to easily say if it is darker or lighter than another red colour, or you might even be able to tell what hue of red it is.  But those cases are, again, relying on our inherent ability to see relative differences.

So instead of ignoring this capacity, in Agile estimation techniques, we leverage it.  When estimating effort, we start by setting a clear baseline for what we are comparing: another piece of work.  The baseline piece of work is often given an “estimate” that is arbitrary and in some non-standard units.  For example, it is common to use “points” when estimating the effort for Product Backlog Items.

When doing relative estimates it is very important to ensure we are comparing “apples to apples”.  Both the piece of work to be estimated and the comparison piece should both be work items that are not yet done!  If you have already completed one of the pieces of work, you have prior knowledge that you don’t have for the work to be estimated.

This last point is subtle, but important.  If you have already done something, you know much more about it.  If you try to compare to something you haven’t yet done, you will be tempted to assume that the two things will be more similar than they may be when you actually get to work on it.  By comparing two pieces of work that you have not yet done, you become much more conscious of the risks of comparing, and that consciousness will help you make better relative estimates.

It is important to note that one side advantage of using relative units for estimation is that it makes it much more difficult to use estimates as a baseline for either measuring performance or for tracking schedule variance, both of which are essentially meaningless in a good Agile environment (which should be almost entirely results-oriented).

Principle Three: Fast

In Agile estimation we don’t care (!!!) about accuracy nor about precision of estimates.  Whoa!  Why is that?  Because estimation is waste.  You can’t sell estimates, and estimates don’t affect the “form, fit or function” of the thing you’re building.  Therefore, both Agile and Lean concur: do your utmost to eliminate that waste.  There are actually lots of Agile practitioners who think estimates are evil (and they have some good arguments!)

In order to do Agile estimation in a maximally non-evil way, we need to make estimation fast!  Really fast!!!  Many of the Agile estimation techniques allow you to estimate a product release schedule lasting as much as a year in just a few hours given a reasonably well-crafted Product Backlog.

There are really only two modestly good reasons for doing estimation in an Agile project or product:

  1. Estimates provide simplified information to the Product Owner to allow him/her to make sure the Product Backlog is ready for the next Sprint (ordered, refined).
  2. Estimates allow stakeholders, including the team doing the work, to generate high-level common understanding and expectations without dwelling on details.

As a business stakeholder, one can do a simple mental exercise.  Ask yourself, “how much money would I be willing to spend to accomplish those two objectives?”  Whatever your answer, I hope that it is a very small amount compared to what you are willing to spend on getting results.  If not, perhaps you haven’t really embraced the Agile mindset yet where “the primary measure of progress is working software” (the Agile Manifesto).

Bonus Principle: We Suck at Estimating

Most people doing estimation in traditional project management try to measure in units like person-days or dollars.  There is no doubt that these units are useful if you can get good estimates.  However, most of the people doing estimation are fundamentally and irredeemably bad at it.  How do I know?  Because they are not wealthy… and have thereby proven that they cannot predict the future.  If you can predict the future, even just in limited circumstances (like estimating effort or revenue), you can leverage that to generate almost untold wealth.  Given that, it is fruitless and wasteful to try to get better at estimating.  Instead, the principles of Agile estimation help us focus our attention on the right things: collaboration, comparative estimates and doing them fast so we can get to the real work, and most importantly: delivering valuable results now.  Understanding these principles helps teams overcome many of the struggles they have in using Agile estimation techniques.

Welcome to LEGOLAND

I was observing a workshop last week that had been put together to create greater cohesiveness in a large organizational team who needed to create a unified vision about their department.

Initially they were broken up into smaller groups to discuss some of the ideas, issues, and challenges they had encountered.  It was obvious how stressed everyone was.  People were speaking animatedly with louder than usual volume, there was a great deal of tension, and everyone seemed agitated and uneasy.

Then came the LEGO.  Mountains of it.  Not just some mismatched pieces either. The kind of LEGO that would have made any child squeal with joy.

LEGO

Each person was asked to create a model of what they thought their department was like at that moment, using the LEGO.  Then another model of what they each envisioned their department could be.  They were then asked to combine the ones they thought were best into a grand model for the department.

I immediately recognized this approach of play therapy used in child psychology, and I was curious to see how it would translate to adults in the workplace.

The effects were wonderful.  The room that was once filled with heated arguments and loads of stress, had transformed into complete calm.  Everyone was so engaged with building their models, they were quiet and relaxed, and whenever there were bursts of noise it was joyful laughter.

Then came the moment of truth, they had to present the large departmental model that they had all collaborated and contributed to making.

They spoke of their vision clearly without argument or dissent.  They shared the space freely encouraging others to speak on parts of the model they didn’t know in detail.  And when they finished their presentation, there was a long pause of silence where everyone was looking at the model, and in each person’s eyes, I saw pride for what they had accomplished together, and a deep sense of hope for the future where it was absent before.

I guess those colourful blocks really do have some magic in them.

Agile Scam – Abusive Comments… What To Do?

This is “my” blog – I write most of the articles, and it is owned by the business in which I am a major partner.  I recently was reviewing comments in the moderation queue and came across this “gem”:

This man is a scammer, agile snake oil only 600, what a bargain. Filthy scamming piece of crap, he’s probably stupid enough to believe his own s**t too.

I’m assuming this person, who is anonymous, is upset either about something I said here on this blog, or possibly something that I (or one of my colleagues) did while we were working with one of our clients.

Several months ago, I was also made aware of a posting about Berteig Consulting (and myself) on Ripoff Report.  I’m not going to link to it, but I will quote it here:

Our company undergoes Agile transformation. Our management decided to hire Berteig Consulting

- a bunch of charlatans spending hours talking absolute nonsense.

They promise sky rocketing performance because they teach us to ( than follows a great number of words with no meaning). We must reflect in Buddish manner, talk to each other, discuss obstacles, be truthful, play stupid games,…. They charge company big money for waisting employees time for endless meetings and providing us with useless information.

Honestly, these sorts of comments make me a bit sad, a bit down.  But here’s what I think about them.

The Agile “Scam”

Let’s make sure we know what we are talking about.  Agile is defined in the the Agile Manifesto.  If you aren’t familiar with it, please take a look.  Basically, the purpose of Agile is to find better ways of building software that are based in practice.  In other words, by people actually building software, and sharing their knowledge, experience and the values and principles that helped them do what they did.

The thing about values and principles is that they are a bit like axioms in formal logic: you can’t prove them.  They are a starting point.  So, if you read the Agile Manifesto and you happen to think that

At regular intervals, the team reflects on how
to become more effective, then tunes and adjusts
its behavior accordingly.

is “Buddish” (whatever that is, presumably Buddhist), and that being “Buddish” is bad or useless, then that is certainly your right.  I can’t prove that this principle of the Agile Menifesto is “right” or “correct” or “always the best thing evar.”  But I like it.  I think it’s good.  I believe in it.  So I guess I am stupid enough to believe my own s**t.  Except that it’s not my own.  I didn’t write the Agile Manifesto.  But I do fully support it.  And, without exception, I think that if work environments tried to put in place the values and principles of the Agile Manifesto, the world would be a (slightly) better place.

So is it a scam?  Well, if it is, I’m being scammed too.  I work crazy long hours, and although I make a decent living, I’m certainly not getting rich off this Agile thing.  When I think of a scam, I think of “get rich quick” or “lose 20 pounds in 20 days” or those sorts of things that promise unbelievable results with little or no effort.

Unfortunately, Agile isn’t like that.  Here is how I think of three Agile methods:

  1. Scrum: incredible results at the cost of incredible pain.  This is kind of like I imagine detox.  An organization is near death and needs to be revived so extreme measures (Scrum) have to be taken.  Requires significant outside help.
  2. OpenAgile: good medium-term results that require significant investment.  This is kind of like making a conscious change from a poor diet with lots of junk food to a good diet: takes discipline, but do-able with good encouragement and support.
  3. Kanban: modest long-term results with relatively low effort.  This is like deciding to change only one thing about your health at a time even if you have lots of health problems.  Lots of small wins accumulate over time.  Doesn’t require much outside help.

Of course, my descriptions of these are _vast_ simplifications for the purposes of discussing the Agile “scam”.  Do professional sports teams or Olympic athletes need coaches?  Probably most people would agree they do need that outside help.  Is coaching sports teams or athletes a “scam”?  Nope.  Not all coaches are good, certainly, but coaching is an essential (sometimes difficult) investment to get to that level of high performance.

Bad Agile

Of course, not all Agile transformations or adoptions are good.  The Agile Manifesto is not easy for most people, teams or organizations to truly embrace.  One of the most common problems I see is that an organization believes that it can have distributed or remote team members and somehow have effective communication among those team members.  This is just one simple example that comes directly from the Agile Manifesto:

The most efficient and effective method of
conveying information to and within a development
team is face-to-face conversation.

I guess, technically, the Agile Manifesto doesn’t out-and-out say that a team must be co-located, but boy-oh-boy does it ever make a difference.

And yet, doing radical collocation is damn hard for most organizations.  So lots of organizations try to adopt Agile techniques without collocation.  And, mostly, their results suck.  Or they try to do collocation, but totally botch it.

Any given principle or value of the Agile Manifesto has its own challenges.  And so most Agile implementations are distant echoes of the incredible results that some rare organizations achieve when they really get Agile.

My Track Record

As a consultant, coach and trainer, I sometimes wish that I could say that I have never failed, that I have never given bad advice.  That’s because in complex human systems, it is very very very hard to sort out cause and effect relationships.  If one of my clients fails to have a dramatic transformation is it because:

  • I gave bad advice?
  • Someone at the client subverted the transformation effort?
  • An executive didn’t support it enough?
  • Market forces destabilized the transformation?
  • The organization’s culture treated Agile as an invasion and fought it off?
  • Agile just wasn’t “right” for the organization?
  • Agile wasn’t adopted soon enough?
  • etc….

On the other hand, I couldn’t very well be a coach, consultant or trainer if I didn’t have a clue.  My colleagues, Paul and Travis (who are named in the Ripoff Reports article), and others whom I have worked with (Nica, David, Mike, Deborah, Christian, another Mike, Allistair, Holleh, yet another Mike,a Michael, and another Michael (wow!), Garry, Jim, Mark, Mary, Sanjiv, yes even another Michael, Julien, Brenda, Derek…) are all smart, experienced, sincere, helpful people… who all know what it takes to produce good results.

The “Secret” Essence of Successful Agile

And, strangely, the essence of it is encapsulated in just a few basic basics:

Truthfulness (vs. hypocrisy, lies and deception)

Collaboration (vs. competition or individualism)

Service to Others (vs. greed and apathy)

and, ultimately, love between people.

So.  To those two people who felt they needed to spew out their hatred, their pain, or whatever it is that they are suffering from, I encourage you to contact me directly.  My email address and phone number are public.  I can’t promise to solve your problem, but I will give you love and whatever help I can extend.

Real Agility Program – Recommendations (Assessment and Playbook)

Recommendations IconWe have already written about how Leadership and Delivery Teams operate in a Real Agility Program.  It’s time to look at our Recommendations component: getting started on the right path for Real Agility.

Recommendations = Assessment + Playbook

In the assessment portion of the Recommendations component, we gather information about the current situation at an organization.  This includes everything from detailed practices, processes and tools, to strategies and organizational culture.  This assessment work is designed to help everyone understand the organization’s current gaps, and what strengths it has that will best support it to cross those gaps to Real Agility.  The Assessment includes an online portion, an on-site portion and an off-site portion.  The assessment work naturally leads to the development of the playbook.

The online assessment requires that each person throughout an organization complete an online survey about corporate culture.  It includes three major sections: existing challenges, sense of urgency, and level of teamwork.  This cultural survey is the foundation of understanding how to be successful with Real Agility.  Managers and leaders are also asked to complete an additional questionnaire about the current environment at the organization.  This includes high-level information about the structure of the organization, client and vendor relationships, and staff.  Additional surveys may also be administered to understand other aspects of the organization.  For example, in an organization that is struggling to use Scrum, we will often use the Scrum Team Assessment.

The onsite portion of the assessment combines in-person interviews and workshops with staff and managers.  Interviews explore aspects of the corporate work environment in more depth and include questions about familiarity with Agile methods, and obstacles that people might see to adopting Agile.  The workshops gather data around current challenges and strengths, success criteria for projects, situational analysis for teams, and existing metrics (or lack thereof).  Typically we need a meeting room committed to our consultants for doing interviews.

The offsite portion of the assessment is used for us to evaluate and analyze the survey, interview and workshop results.  We also use some time to review any relevant documentation such as process templates, org charts, governance requirements, etc.  We may also use some of this time for follow-up phone calls or emails to clarify aspects of the assessment results.  Finally, this offsite work is also where we do the bulk of the development of the recommendations in the playbook.

Several aspects of our assessment are based on the OpenAgile Catalyst Assessment Tools which are open-source and can be found online.  We also have a number of proprietary tools.

The playbook maps out a path to a successful Real Agility transformation.  It is a road map that helps leaders, managers and team members make good business decisions as they strive for Real Agility.  The playbook aids the organization to effectively and appropriately launch Real Agility teams: management teams, project teams, and operational teams.  The Real Agility Program playbook includes analysis of the assessment results, recommendations for work that the organization can do on its own and suggests outside assistance that enhances Real Agility results.  Two critical questions that are answered in the Playbook include:

  • What Agile method or methods should we be using and why?
  • What organizational change approach should we take and why?

We deliver the recommendations in the form of the playbook and an executive summary slide deck in an iterative and incremental fashion so that stakeholders can give us early feedback and so that we can adapt our assessment agenda as we go along.  The recommendations include ideas about organizational structure, staffing, governance changes, departmental relationships, tooling, and many other aspects of how an enterprise can best become and Agile enterprise.

Following the Recommendations in the Real Agility Program playbook results in huge time-to-market improvements, 200% (or better) productivity boost for delivery teams, and extremely satisfied customers and staff.
