re:Work - Many hands may not make light work

Eventually, all the important work is done before and after meetings by four or five influential members. As Parkinson would have it, and numerous studies now confirm, many hands do not make light work when it comes to teams. After devoting nearly 50 years to studying team performance, the late Harvard researcher J. Richard Hackman concluded that four to six members is the best team size for most tasks, that no work team should have more than 10 members, and that performance problems and interpersonal friction increase “exponentially as team size increases.”
