Mix it up.

To create creative groups of people don’t rely exclusively on cohesion – bring in new people with new ideas and different ways of doing things.
“We found that teams that achieved success — by producing musicals on Broadway or publishing academic papers in good journals — were fundamentally assembled in the same way, by bringing in some experienced people who had not worked together before. The unsuccessful teams repeated the same collaborations over and over again.”
“We discovered that assembling a successful team depends on choosing the right balance of diversity and cohesion — achieving the bliss point intersection of the two.” Diversity represents new collaborations while cohesion comes from repeat collaborations.
Dream teams thrive on mix of old and new blood
