Forming, Storming, Norming, and Performing is a framework for understanding how groups develop and become productive. Introduced by psychologist Bruce Tuckman in 1965 and later revised in 1977 to add Adjourning, the model describes common patterns of behavior as a team forms, stabilizes, and works toward its goals. It is widely used in organizational behavior, project management, and team-building to guide expectations and interventions.

In the forming stage, members meet and orient themselves. They test boundaries, seek information, and clarify aims. Roles and leadership are often unclear, and politeness and dependency on the leader are common as the group seeks direction.

During storming, members push for influence and disagree over goals, methods, and authority. Tensions may include competition, criticism, and resistance to leadership. Without effective conflict management, progress can stall, but this stage can also clarify priorities and relationships.

In the norming stage, the group establishes norms, processes, and shared expectations. Trust grows, collaboration improves, and members begin to work more cohesively with clearer roles and a more stable leadership dynamic.

The performing stage is characterized by functional, autonomous operation. The team focuses on task execution, problem solving, and achieving goals with high interdependence and relatively low process interference.

Adjourning, sometimes called mourning, occurs when a project ends or the team disbands. Members reflect on outcomes, release resources, and acknowledge contributions, though some may experience a sense of loss or unfinished business.

Applications and cautions: the model offers a useful heuristic but is not universal. Teams may progress non-linearly, revisit earlier stages, or skip stages. Cultural context, project type, and virtual collaboration can influence dynamics, and critics note that alternative theories may better fit certain groups.
