Lean, Agile and Capitalism - Just a Thought

Monday, December 18th, 2006

It occurred to me to ask: If the “invisible hand” in the free markets of capitalism is making for efficient markets, efficient work… then why is there some much room for improvement when we start using non-competitive, collaborative techniques such as lean and agile?

And if these collaborative techniques work on a small scale to improve efficiency, does this mean that we could do this across organizations as a “replacement” for capitalism somehow?

In agile methods, we “assume positive intent” on the part of individuals. What if we could do this across organizations? I’m not living in a dream world yet, but I think I have an inkling of what it might look like: Toyota and its collaborative, leaned-out supply chain.

The Case for Context Switching

Wednesday, November 15th, 2006

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.

An Introduction to General Systems Thinking

Thursday, April 20th, 2006

I recently completed reading An Introduction to General Systems Thinking by Gerald M. Weinberg. Since it was mind-blowingly fantastic, I thought I should probably write a brief review of it so you-all can check it out!

Dehumanizing Documents

Monday, March 27th, 2006

This past weekend, I was honored to host a small gathering of Agile coaches at my home. Our conversation varied over many topics and I’ll be covering some of them in the upcoming days. The first I would like to cover came from a comment that Christian Gruber made. In the Agile Software Manifesto there is the statement that we value “working software over comprehensive documentation” and in the Agile Axioms we say “we are creators”. These two statements are closely related.

Agile, the Adult Educator and Ethical Considerations

Monday, October 10th, 2005

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.

Harvard Business Review Article

Thursday, August 18th, 2005

I highly recommend this article on Collaboration Rules. Great stuff in there about developing teams, developing organizations and how important communication and trust are to doing so. The article draws examples from and compares the open-source development and maintenance of the Linux kernal and the operation of the Toyota Production System.

The Viable Systems Model

Wednesday, August 17th, 2005

Agile Work is a system that can be created inside many types of organizations and work environments. I recently came across an interesting article about the viability of systems. The article describes an interesting recursive breakdown of systems into sub-systems of specific types. Over the course of the next few weeks, I will use this model to try to analyze Agile Work to see if it is viable.

The Transparent Society

Tuesday, August 9th, 2005

The Transparent Society, an essay by David Brin is an excellent statement about the possibilities and challenges that technology presents to us as a society. What is interesting about this paper is that it presents a possible society that is very similar to some of the goals in establishing an agile environment: open communication, accountability, free access to information and status, and close collaboration.

Generalizing Specialists

Saturday, August 6th, 2005

The term “generalizing specialists” has come to mean an individual who has a particular area of deep expertise but also has experience in a large number of other areas that may not be directly related to their core area. This type of person typically has strong talent in their specialty but also has a generally strong talent for learning new skills and ideas quickly. The origin of the term seems to be in the software industry referring to programmers who can do other software-development related tasks.

In self-organizing teams, a generalizing specialist is a more valuable team member than a pure specialist. The pure specialist often has an attitude that they should not need to do work outside their specialty. This can be destructive to the team’s morale. On the other hand, the generalizing specialist is willing and able to learn new skills - to stretch as the needs of the team change. And since change is natural, this is an essential attitude for team members.

However, we are usually trained, and strongly encouraged to have a deep specialty. This approach to education and training is a natural consequence to the typical organizational model for work and society. Therefore, if a team is converting to agile work methods, people need to be coached to stretch themselves and learn new things. For some people, particularly those who already have multiple hobbies outside work, this is an easy transition to make. For others, it is a very difficult transition. In some extreme cases, this may call for the removal of someone from the team. (Note: I have never seen this myself and I only mention it with great reservation. I strongly feel that only those who could be called “ill” will be so incapable of changing their way of working. For other recalcitrants, it is usually a matter of motivation.)

Other terms that are similar to “generalizing specialist” include “craftsperson”, “renaissance man”, and “polymath“.

Just In Case You Haven’t Seen It Yet

Thursday, August 4th, 2005

There is a fantastic article about software productivity: http://www.joelonsoftware.com/articles/HighNotes.html. I love Joel’s writing style, and this article in particular has important lessons for us all, regardless of our profession: find what you can be the best at, and do that. Interestingly enough this is part of the message of the book Good to Great but applied to a whole corporation. It also applies in the context of self-organizing teams: each individual should be able to find/learn in what way they can best contribute and do that more than they do other stuff.

Broadcast Mode Communication

Monday, August 1st, 2005

The book “The Mythical Man-Month“* discusses some of the reasons that larger teams are inefficient. The main concern is with the number of possible connections between team members. If you have two team members, there’s only one channel of communication. However, if you have n team members, then you have n(n-1)/2 channels… which grows quickly (order n^2) as n becomes larger. If one is required to work with a large team, say more than 10 to 12 people, it becomes imperative to find ways to improve communication efficiency.

One of the best ways to do this is to use broadcast mode communications. Information radiators are a simple broadcast mode tool. In a subtler way, having the team co-located** also takes advantage of broadcast mode communication: if everyone can overhear all the conversations that are going on in a room, then people can tune in when they hear something of relevance.

It is important to note that there are several other forms of broadcast communication that are useful in certain circumstances: e-mail, blogs with RSS or Atom feeds, analog radio, television (if you can think of others, please let me know in the comments). These tend to be more useful for very large communities. Radio and television have severe limits: they are not easily used in a communal fashion.

Some forms of communication may seem to be broadcast, but in fact are not. A simple web site is not because it requires that people poll it to see if it has been updated. Conference calls are marginally broadcast in that while they are occuring, everyone participating hears everyone else. However, a conference call requires active synchronized attention on the part of all the participants.

The subject of media and communication is a vast one. Some of the best writers include Marshall McLuhan and Gregory Bateson. However, there are many many more.

Applicability Matrix Tool for Iterative Delivery

Monday, July 25th, 2005

AMT-IterativeDelivery.png

Notes:

1. Iterative Delivery is a specific way of managing queues of work. As such, rote work is generally better served by other applications of queuing theory.

2. There is one universal condition under which iterative delivery is awkward, if not inadvisable. If one’s horizon of predictability is longer than the size of a work package by some substantial amount (e.g. 2:1 ratio), it can be more natural to use queuing theory and a pull system to flow work through the team. The actual ratio between the horizon of predictability and work package size that is used to switch over to a queue system must be determined empirically in your own circumstances. This empirical analysis can be done using a regular process reflection meeting.
