This is the first stage of team development, commonly referred to as the 'testing and dependence' stage, in which team members meet each other, form initial impressions, and begin to establish team norm.

Norm: The interpersonal roles that members are expected to follow.

This stage begins to occur as the process of organizing tasks and processes surface interpersonal conflicts. Leadership, power, and structural issues dominate this stage. This stage can highlight the lack of unity and polarization around interpersonal issues. Hostility and resistance to leadership structure and teamwork is common in this stage due to the difference in emotional responses.

This stage is when team members begin to settle into their roles, group cohesion grows, and positive team norms develop. idiosyncrasies and personal opinions are shared. Be cautious during this stage because norms (good and bad) will set the precident for the team for the remainder of the project.

Descriptive norms: "What is"

Injunctive norms: "What should be"

This stage (the final stage in the original model) is highly productive both personally and professionally, 'functional role relatedness' is developed. The team is flexible as individuals adapt to meet the needs of other team members, and their performance improves because the team has matured into an effective, fully functioning team with the groups task completion as the priority. effective groups will spend 80-85% of their time on task completion.

In 1977, Adjourning was added as the final stage in the updated Tuckman's linear model. In this stage, the team's goal(s) have been accomplished. The emphasis is on wrapping up final tasks and documenting the effort and results. Celebration or for others sadness and disappointment are displayed in the disbanding and conclusion of the group.
