Reading
The previous chapter define the problems encountered in software development, the lean terminology (see also LeanThinking) and how it applies to software
- Practice 0 : Source Code Management and Scripted Builds
- Practice 1 : Automated Testing
- testing itself is a way to produce and organize knowledge
- e.g. to generate API examples
- thus be more welcoming for a community if one hopes to build an ecosystem
- "when you are creating automated tests as a part of your development process, you quickly learn to design the code in a manner that ensures that it is testable." (p40)
- Practice 2 : Continuous Integration
- pulled SCM code -> build -> tests -> documentation generation -> deployment
- with reports on every step of the way, including tests and code coverage
- importance of the stability of environment of the CI server
- feedback is so fundamental it will probably out-weight the cost of setting up such a system, even with a dedicated machine
- Practice 3 : Less Code
- requirements also should improve over time
- "eliminate unnecessary code [diet], employ good coding practices [get in shape], and justify any new code [maintain healthy habits over time]." (p73)
- Practice 4 : Short Iterations
- the importance of demo with feature to test to have actual feedback before moving on
- for the customer but also for the developers to achieve satisfaction
- the fallacy of "fake" iteration by simply splitting large initial requirements rather than actually re-evaluating needs and their priorities after each tests
- "Emergent design allows the component-level architecture to evolve as requirements become more defined." (p93)
- Practice 5 : Customer Participation
- CRACK customer : Collaborative, Representative, Authorized, Committed, Knowledgeable (p100)

Overall remarks and questions
- recurrent warning that everything has to be socially accepted, throwing the ideal process to a team will not necessarily result in proper adoption
Synthesis
So in the end, it was about X and was based on Y.
Critics
Point A, B and C are debatable because of e, f and j.

Post-reading model
Draw a schema (using PmGraphViz or another solution) of the situation of the area in the studied domain after having read the book. Link it to the pre-reading model and align the two to help easy comparison.
