How Long Should Agile Teams Stay Together? This is such a good question. I recently got an email from Mike Cohn where we have a bit of a discussion surrounding The Tuckman model, (Forming, Storming, Norming, and Performing). My thought is that mature Agile teams should be self-organized and self-regulated. This means that they have the power to adjust in order to maintain an AWESOME culture. What are your thoughts?
