It seems that the rhythm to developing software in XP marches to a beat marking
TwoWeeks. What is magic about
TwoWeeks?
- Nobody can estimate anything with any accuracy of duration greater than TwoWeeks.
- How wrong can you be in TwoWeeks?
I tried
OneWeek instead of
TwoWeeks in a project recently, and I think
OneWeek is just too short for useful stories to emerge. We ended up tacking simpler stories first since they fit the week boundary, instead of the riskier ones.
