The document summarizes the 5 stages of group development as described by Tuckman in 1963: 1. Forming - Members get acquainted and determine the group's purpose. Guidance is needed from the leader. 2. Storming - Emotional tensions arise as members compete for roles and confront each other. 3. Norming - The group comes together as a coordinated unit by developing group norms and allocating roles. 4. Performing - The mature group works efficiently to accomplish complex tasks and handle disagreements creatively. 5. Adjourning - The group ends its task and disbands, with ideally integrated members willing to work together again.
