Intermittent collaboration gives the best results. Researchers recently devised an ingenious experiment to assess the effectiveness of team-based solutions to complex problems. Bernstein and colleagues found that “groups whose members interacted only intermittently . . . had an average quality of solution that was nearly identical to those groups that interacted constantly, yet they preserved enough variation to find some of the best solutions too.”1 Intermittent collaboration found better solutions than constant interaction.
