Which phase is NOT part of Tuckman's Model?

Tuckman's Model, developed by Bruce Tuckman in 1965, outlines four key stages that teams typically progress through as they develop: forming, storming, norming, and performing. Each of these stages describes different aspects of team dynamics and behavior.

The phase referred to as "coalescing" is not part of Tuckman's original model. The model specifically tracks the journey of a team through the essential phases that contribute to team effectiveness and cohesion. In the forming stage, team members come together and get to know each other. The storming phase involves conflict as team members assert their ideas and opinions. The norming phase occurs when the team starts to establish norms and work together more effectively, while the performing stage is characterized by high performance and collaboration among team members.

By understanding these established phases, one can see that "coalescing" does not align with the terminology or the progression outlined in Tuckman's Model, making it the correct answer to identify as not part of the model.
