Well maybe not easy and maybe not 3 but Luis A. Nunes Amaral and Brian Uzzi from Northwestern University do have some suggestions for how to do it. In a paper they jointly published today they share the results of a study of the make up of a range of high performing teams. These teams range from Broadway plays to academic research teams. What they found is that the teams with the best results were a careful balance of diversity and cohesion. If balance right this combination can give you strong teamwork combined with a broad range of perspectives that allow creative teams to excel. Luis and Brian are part of the Northwestern Institute on Complex Systems (NICO) which specializes in studying the interactions that take place in complex systems.
