just because cross-functionality can achieve great results, you shouldn’t play Noah and throw two of everything into a team. The team dynamic only works well in small teams. The classic formulation is seven people, plus or minus two, though I’ve seen teams as small as three function at a high level. What’s fascinating is that the data shows that if you have more than nine people on a team, their velocity actually slows down. That’s right. More resources make the team go slower.
