I used to be pretty dogmatic about the upper limits of team size. But once I started becoming aware of the value of having complexity located inside a team, now I’m not so sure about the 5-9 rule.

In this episode, Richard and Peter answer the question, what’s the best size for an agile team? The Scrum Guide says 5-9, but how does the Humanizing Work team think about it?
