In short
Bruce Tuckman (1938–2016) was an American psychologist whose 1965 article proposed that small teams develop through distinguishable stages — forming, storming, norming, performing — and added adjourning in 1977. The names became the standard shorthand for where a team is.
1. The framework
Tuckman's review of fifty group studies found the sequence recurring across settings: a polite beginning, friction as roles and norms are contested, consolidation into working agreements, then performance. The insight that stuck: storming is development, not failure.
Teams that read the model stop diagnosing their conflict phase as a people problem and start treating it as a stage to be worked through with structure.
2. Where critics push back
Later research shows the stages overlap, loop back, and vary with membership churn — the model describes a common path, not a fixed timetable.
