What is the final stage of team growth that was added later by Tuckman?

The final stage of team growth added later by Tuckman is appropriately identified as Adjourning. In Tuckman's model, which originally included four stages—Forming, Storming, Norming, and Performing—the Adjourning stage was introduced later to address the process teams undergo when their work comes to an end.

During the Adjourning phase, team members reflect on their accomplishments, celebrate their successes, and begin to disengage from the team as their tasks are completed. This stage is essential for providing closure, allowing team members to acknowledge their contributions, and facilitating a smooth transition as they move on, whether to new projects or back to individual roles. Recognizing this phase is crucial in understanding team dynamics and the emotional aspects of team disbandment.

The other stages—Norming, Storming, and Performing—focus on the developmental and operational aspects of team functioning but do not encompass the end-of-project dynamics that the Adjourning stage addresses. Understanding this full spectrum of team growth emphasizes the importance of both initiating and concluding team efforts effectively.
