On the distinction between work groups and teams

Groups do not become teams simply because that is what someone calls them…A working group’s performance is a function of what its members do as individuals. A team’s performance includes both individual results and what we call “collective work products.”…Whatever it is, a collective work product reflects the joint, real contribution of team members…The essence of a team is common commitment. Without it, groups perform as individuals; with it, they become a powerful unit of collective performance.
