- planning problem because the true done state is the one after testing, and it is hard to plan for an iteration because there will be an unknown amount of requirements that will fail from the QA done state and fall back to the development iteration.
Variations
The done state originally evolved out of the general idea of “working software” from the Agile manifesto. But what is working software? In XP, it was originally software that passed unit and acceptance tests. As the community gained more experience with continuous integration in larger projects, the constraints were different, and thus evolved the idea of “as close to deployable as possible.”
