During improvement phase its very easy to cross the plan boundary - we want to take care about all possibilities and possible changes that can happen in our project. On the another hand erstwhile we are under the time force we take shortcuts which could in the end increase cost of even simple changes. How to deal with "overdesign"? How (at the same time) don't close for improvements and changes? erstwhile we should make crucial method decisions and erstwhile accept method debt? This session is about actual stories, mostly about immense mistakes, but besides sometimes about decisions which in the end were very successful. The session for all who don't want to end up with task that need's to be rewritten to add a fresh button. The session for all who cares.
