To review Chet Hendrickson’s retrospective paper on his book Extreme Programming Installed, I went back in time myself. Back to my first experience with Extreme Programming.
In September 2003 I was asked to urgently take on a project as project manager. Customer approval was late but the predicted delivery date remained (December).
A 15 min introduction convinced me of eXtreme Programming. Because so much was incorporated that was traditionally so easily forgotten or overlooked. We convinced management, and off we went (October). After 3 iterations (of 3 weeks) we delivered… in time and on budget!
Because I considered myself too illiterate (after all, we only did it) to present the project at Javapolis 2003, I started reading some books. The inevitable Extreme Programming Explained (‘Embrace Change‘), Planning Extreme Programming and… Extreme Programming Installed. It was remarkable to find that our ‘naive application’ was an extraordinary match with what I was reading. Presentation went very well.
In 2004 I started using Scrum as process and certified as a ScrumMaster. During follow-up projects for our satisfied customer we kept combining Scrum and XP. However, we had to operate within a context of realizing a (negotiable) scope in a given timeframe. So along the way (2004-2006) additional practices, tools and views were embedded, to finally become my My.Fragility* framework.
The framework holds following (partially XP based) Quality Loops:
Implementation of Engineering Standards. To be performed every day:
- A pair writes all code upon a Test First basis (including Selenium GUI tests)
- Checked in code is tested in a Continuous Integration system (multiple times a day) and can be refactored
- A ‘guide’ (additional, explicit role) functionally tests a stable, CI’ed version (multiple times a day) and feeds back results to the team
- A functional working version may be deployed for performance testing (running overnight)
* The name of the framework has its roots in the big relief I felt when morphing from project manager to ScrumMaster. The option to be fragile (agility through fragility), of not constantly having to intimidate people. Because, after all, it’s just a matter of talents and roles, not of… hierarchical slavery.
