The Simplest Systems Thinking Exercise - How to Make Toast.

For many years one example of process thinking, resource gathering, requirements, implementation and acceptance criteria has been the exercise - make PB&J sandwiches.  I've done this with groups to discuss the simple task that we typically overlook as "experts" in sandwich making, that perhaps a 5 year old will find difficulty glossing over the - get bread - instruction.


Here's a TED Talk by Tom Wujec who has analyzed a similar exercise and draws some powerful conclusions from many iterations.  Watch it and then rethink the simple acts in your life.




So tell me again why group collaboration is important when you are solving wicked problems?

I was out walking my dog, Malibu and we stopped at a tree with lights wrapped around it's trunk.  They didn't go too far up the trunk, and I wondered if the humans ran out of effort... then I imagined the lights wrapping themselves around the tree.  What kind of motions would a set of lights on a wire learn?  I assumed it would be an inchworm motion.  I think I've seen this animated so it must be correct.  But then I tried to apply the motion to the long strand of lights - and something felt wrong... it had a lot of drag.  So how does an inchworm move?  Does it use it's six legs (on the front of the body) to pull the hind end forward?  Would that work for a strand of lights?

Let's watch - study an inchworm.

Pondering...  how many people can tell us - how does an inchworm move?

How would nature solve the motivation problem for a strand of lights?

David's notes on "Drive"

- "The Surprising Truth about what Motivates Us" by Dan Pink.

Amazon book order
What I notice first and really like is the subtle implication in the shadow of the "i" in Drive is a person taking one step in a running motion.  This brings to mind the old saying - "there is no I in TEAM".  There is however a ME in TEAM, and there is an I in DRIVE.  And when one talks about motivating a team or an individual - it all starts with - what's in it for me.

Introduction

Pink starts with an early experiment with monkeys on problem solving.  Seems the monkeys were much better problem solver's than the scientist thought they should be.  This 1949 experiment is explained as the early understanding of motivation.  At the time there were two main drivers of motivation:  biological & external influences.  Harry F. Harlow defines the third drive in a novel theory:  "The performance of the task provided intrinsic reward" (p 3).  This is Dan Pink's M…

Exercise:: Definition of Ready & Done

Assuming you are on a Scrum/Agile software development team, then one of the first 'working agreements' you have created with your team is a 'Definition of Done' - right?



Oh - you don't have a definition of what aspects a user story that is done will exhibit. Well then, you need to create a list of attributes of a done story. One way to do this would be to Google 'definition of done' ... here let me do that for you: http://tinyurl.com/3br9o6n. Then you could just use someone else's definition - there DONE!

But that would be cheating -- right? It is not the artifact - the list of done criteria, that is important for your team - it is the act of doing it for themselves, it is that shared understanding of having a debate over some of the gray areas that create a true working agreement. If some of the team believes that a story being done means that there can be no bugs found in the code - but some believe that there can be some minor issues - well, …

Team Performance Model - by Drexler and Sibbet

Many of you have all heard of the Tuckman model of team dynamics (Forming, Storming, Norming, Performing).  It was created in 1966 and has become the most popular model for describing team behavior.  Is it time to level up in your mental model of team dynamics?  Are you ready for a richer more functional model?

Orientation - Why am I here?
"Orientation is about understanding the purpose of a team and assessing what it will mean to be a member.  you need to understand the reason the team exist, what will be expected of you and how you will benefit from membership.  In a new team, these are individual concerns, because the group is only potentially a team.  that is why these concerns are illustrated as occurring in your imagination at an intuitive level.  As a team leader it is important to provide time and space for people to answer these internal questions themselves."

Keys to when Orientation challenges are resolve…

Refactoring - examples from the book

Martin Fowler's book Refactoring:  Improving the Design of Existing Code has a simple example of a movie rental domain model, which he refactors from a less than ideal object-oriented design to a more robust OO design. Included in this Refactoring_FirstExample.zip Zip file are the Java source code files of the Movie, Rental, and Customer classes. Along with a JUnit CustomerTest class. Using these example source files you too can follow along with the refactoring that Fowler presents in the first few chapters of his book.


Do You Put “CSM” After Your Name?

I’ve noticed a new trend—people have been gaining titles. When I was younger, only doctors had initials (like MD) after their names. I always figured that was because society held doctors, and sometime priests (OFM) in such high regard that we wanted to point out their higher learning. I hope it was to encourage others to apply themselves in school and become doctors also. Could it have been boastful?

The Wikipedia describes these “post-nominal initials”:
Post-nominal letters, also called post-nominal initials, are letters placed after the name of a person to indicate that the individual holds a position, educational degree, accreditation, office, or honor. An individual may use several different sets of post-nominal letters. The order in which these are listed after a name is based on the order of precedence and category of the order. That’s good enough for me.
So I ask you: is the use of CSM or CSP an appropriate use of post-nominal initials?
If your not an agilista, you may wonder …
