Smaller teams-better teamwork: How to keep project teams small

Scholars and practitioners have long suggested that smaller teams perform better teamwork, yet it is surprising to find that many organizations are using teams of 10 and more members. This paper explains how large team size affects teamwork. Moreover, it suggests four ways to keep teams small: (1) Create a multiteam project; (2) create a core team and an extended team; (3) outsource tasks and define team-external contributions; and (4) keep members on the team only for specific project phases.
