The stages of team development help explain the needs of a team throughout its lifecycle. This article provides an excellent summary for busy people.


Tuckman’s model of the five stages of team development is one of the most influential teamwork theories. Understanding it is therefore one of the fundamental team building basics for team leaders.

At each stage, a team has different needs and questions. These must be addressed if the group is to become a high performing team. An effective team leader will structure team building initiatives according to the stages of team development.

The Storm before the Team Performs. The Life Cycle of Teams

by Sharon Feltham, Excellerate

The Storm before the Team Performs

  • Groups go through stages before they perform well 
  • Conflict is part of the group formation process

The most influential model of the team developmental process is that of Bruce W. Tuckman (1965). He gave us a way to interpret and make sense of the various stages groups pass through on their way to becoming an effective team.

Tuckman described this journey as five distinct stages of team development: forming, storming, norming, performing, and adjourning.

At first glance the model suggests that teams will move through each of these stages in a predictable sequence however, in reality teams progress through these stages and remain at the different stages for varying lengths of time. Some teams can become stuck in a particular stage and fail to progress while others can regress to an earlier stage of team development.

The Five Stages of Team Development

Forming: Stage 1 of the Stages of Team Development

What does it look like? Team members are reserved and polite, putting on their best behaviour to create a good first impression. Conflict is avoided at all costs because of the need to be accepted into the group. There may be a sense of excitement and opportunity, but also cautiousness and uncertainty about the future. Team members reflect not only on the tasks at hand, but also about each other. Initial ground rules are established as the team begins to discover how to work together.


Storming: Stage 2 of the Stages of Team Development

What does it look like? Differences in opinion are more common and are expressed more openly. Conflicts emerge around interpersonal issues and task needs. Power struggles may emerge as leadership is challenged and factions begin to form. Team members compete for positions, challenge goals, the group influence and resist task requirements. Note: Many groups commonly stall at this stage.


Norming: Stage 3 of the Stages of Team Development

What does it look like? A sense of renewed optimism as the team begins to feel a sense of team identity. It experiences increased cooperation as roles and responsibilities become clearer and agreement on norms and expectations for behavior are reached.




Performing: Stage 4 of the Stages of Team Development

What does it look like? Reaching this stage is largely dependent upon the successful transition through the previous stages. The team knows clearly what it is doing and why. Relationships are strong and while disagreements may occur they are resolved quickly and positively. Roles become flexible and functional, and group energy is channelled into the task. There is maximum work accomplishment, interdependence, personal insight and constructive self-change.

A team at the Performing Stage can either:

  1. Return to the forming stage as group membership, leadership and the team’s purpose changes,
  2. Decline into “dorming” stage as the group becomes complacent or
  3. Adjourn as the group successfully reaches its goal, completes its work and disbands.

The Stage of Phantom Performance: Dorming

What does it look like? (This stage is not included in Tuckman’s original work it was identified by later writers). Once the performing stage is reached, there is a risk that the team will neglect the task of maintaining commitment. This neglect will see the team slide gradually into the cosy dosey stage of Dorming. In this stage the team becomes complacent, satisfied by past achievements they are content to leave challenges to “someone else”.


Adjourning: Stage 5 of the Stages of Team Development

What does it look like? Adjourning is typically related to the end of a project team however, its also relevant when the purpose and structure of team changes substantially due to sale, merger or a restructuring process. This stage can be particularly stressful where the dissolution of the team is unplanned. This stage involves the disbandment of the team, termination of roles and the completion of tasks. This stage is also referred to as ‘mourning’ given the sense of loss experienced by some team members.
