MAKE THE TEAM BIGGER
Solve coordination problems by adding more people to coordinate.
Invite every relevant manager, specialist, and stakeholder to every project discussion. Keep the same approval model while expanding the group. When decisions slow down, conclude that more alignment is needed and enlarge the next meeting.
Team expansion that increases coordination burden without decision clarity.
Evidence, with limitations.
Claim
Team size has no universal positive or negative effect on performance. Meta-analytic evidence shows large contextual variation, with benefits from added human capital in some tasks and process losses where coordination demands dominate.
Evidence
A meta-analysis of more than 21,000 teams found the average relationship between team size and task performance was essentially zero but highly variable; task complexity and coordination requirements helped explain when larger teams helped or hurt.
Scientific boundary: Team-size effects are moderated by task interdependence and coordination; neither larger nor smaller teams are uniformly superior.
