Who says you need "stable" teams in order to build a successful software company? While the addition or removal of one person from a team means you have a "new team", there is a myth out there about "stable" teams. When your team compositions change it doesn't mean you're doing it "wrong" - it's just a different way of working. We've thrived through dynamic reteaming - the act of moving team members around teams in different ways. Even with changeable teams we still deliver value weekly to our customers. For the past 9 years, from startup to public company, we've learned a lot about reteaming. In this talk I'll share the what, why and how about reteaming with you.
