Bruce Tuckman proposed a model of team development with five stages: forming, storming, norming, performing, and adjourning. In the forming stage, team members are anxious and unsure of goals. Storming involves conflict as roles and ideas are discussed. During norming, trust increases and goals become clearer. In performing, the team works effectively toward shared goals. Finally, adjourning occurs when the team disbands after completing its task. The document provides characteristics and suggestions for how to support a team at each development stage.
