(A typical XP iteration is 2 weeks, but I suggested 1 week iterations because when a team is in trouble - such as when they have a fretful customer - they must become >more< extreme, not less.)So, 2 weeks is extreme, 3 weeks is less extreme, and 1 week is more extreme?Hey, if being extreme is good, why not make the iterations be 2 seconds?Would that be "way more" extreme?
Interestingly enough, the code for the computer in the Mercury space
capsule was developed using iterations of four *hours*. And tests
were written before code. (According to Craig Larman's wonderful
history of iterative development paper in IEEE)
I often use four hour iterations when teaching XP or TDD in courses.
Amazingly enough, it works pretty well. Even so, I prefer one-two
week iterations.
