Coal in your bug tracking stocking this Christmas?

What is your plan for being a better developer next year?  What's the technique that will repay your efforts many fold?  Testing - automated test to be specific.  There are all types of automated testing.  The agile mind set thinks of testing first, not in a reactive manner, but as a preventative and design effort.

"For three years, The Container Store has been using application performance management (APM) technology from AppDynamics to locate bugs in the website, target them immediately and fix them.
Sometimes there's a slowdown in a particular region. Other times it's from a certain database and often from a single line of code. Just this year, the Container Store upped its contract with AppDynamics, buying more software so the company can test new features before deploying them and minimize the number of live fixes necessary.
"We said we want to be more proactive instead of reactive," said A.J. Azzarello, a quality assurance engineer at The Container Store in Dallas. "We can catch errors and slow response times in test prior to production so they never impact our customers."

You might enjoy watching David Evans presentation Turning Tests into (Living) Documentation.  In this 20 min. video he should be able to teach you some very important concepts of BDD.


One Artifact: 3 roles - Specification, Test, Documentation; resulting in more value, and requiring collective ownership.

Charictistic of a good artifact:  Title - just a few words that you would use to search in google; Rules - the business rules written in their vernacular using SME's terms; Examples - testable cases illustrated via rules, explicit real world values (but only relevant data), and don't forget the counter-examples (edge cases).

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…

Elements of an Effective Scrum Task Board

What are the individual elements that make a Scrum task board effective for the team and the leadership of the team?  There are a few basic elements that are quite obvious when you have seen a few good Scrum boards... but there are some other elements that appear to elude even the most servant of leaders of Scrum teams.









In general I'm referring to a physical Scrum board.  Although software applications will replicated may of the elements of a good Scrum board there will be affordances that are not easily replicated.  And software applications offer features not easily implemented in the physical domain also.

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, …

What belongs on the Task Board?

I wonder about these questions a lot - what types of task belong on the task board?  Does every task have to belong to a Story?  Are some tasks just too small?  Are some tasks too obvious?  Obviously some task are too larger, but when should it be decomposed?  How will we know a task is too large?

I answer these questions with a question.  What about a task board motivates us to get work done?  The answer is: T.A.S.K.S. to DONE!



Inherent in the acronym TASKS is the point of all tasks, to get to done.  That is the measure of if the task is the right size.  Does it motivate us to get the work done?  (see notes on Dan Pink's book: Drive - The surprising Truth about what motivates us) If we are forgetting to do some class of task then putting it on the board will help us remember.  If we think some small task is being done by someone else, then putting it on the board will validate that someone else is actually doing it.  If a task is obvious, then putting it on the board will take vi…

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.
