It's incredible to think that Saturday Night Live and Google, given their very different goals, create teams of people similarly. But as reporter Charles Duhigg discovered, they very much do. For SNL, it was creator Lorne Michaels who managed a team of writers and comedians to produce a high-quality show under extremely rigid time constraints. At Google, the original hypothesis about teams — that the right combinations of personalities is what made them effective — proved false. What they found instead is that the coherency of group norms is the determining factor: in other words, is everyone on the same page about how the group works, and does everyone have a voice? If so, you can expect some good results.
Duhigg's latest book is Smarter Faster Better: The Secrets of Being Productive in Life and Business.
