A new team can look calm while still being uncertain. People are polite, roles are unclear, and difficult questions remain unspoken. Later, disagreement appears. If the group works through it, shared habits develop and coordinated performance becomes possible.
Psychologist Bruce Tuckman described this pattern in 1965 using four stages: forming, storming, norming, and performing. In 1977, Tuckman and Mary Ann Jensen revisited the model and added a fifth stage, adjourning, to represent a group's ending or transition.
1. Forming: Finding Direction
During Forming, members are learning why the group exists, who is involved, and how the work will happen. People may be enthusiastic, cautious, dependent on the leader, or reluctant to reveal disagreement before they understand the social environment.
Typical signs include broad discussion, many questions, unclear ownership, polite interactions, and limited progress on complex work. This is not laziness; the team is building an initial map of purpose, people, and expectations.
What helps:
- Explain the purpose, desired outcome, and immediate priorities.
- Clarify roles, decision rights, boundaries, and available resources.
- Create simple working agreements for communication and meetings.
- Give the team an achievable early task that builds shared experience.
2. Storming: Working Through Differences
As people become more comfortable, differences surface. Members may challenge goals, methods, authority, workload, or one another's assumptions. Competition, frustration, subgroups, and uneven participation can emerge.
Storming is often treated as a failure, but disagreement can reveal information the group needs. The danger is not conflict itself; it is conflict that becomes personal, unsafe, or impossible to discuss productively.
What helps:
- Separate disagreement about ideas from attacks on people.
- Make hidden concerns and competing priorities discussable.
- Use a clear process for decisions and conflict resolution.
- Address harmful behavior directly instead of waiting for it to disappear.
- Revisit goals and roles when the conflict exposes genuine ambiguity.
3. Norming: Building Shared Ways of Working
In Norming, the group develops clearer expectations and more stable relationships. Members understand how their work connects, trust grows, and routines become less dependent on constant direction from the leader.
The team may establish norms for giving feedback, sharing information, making decisions, and handling deadlines. Differences still exist, but people have more reliable ways to discuss them.
What helps:
- Make successful working practices explicit so they can be repeated.
- Distribute ownership instead of keeping every decision at the top.
- Notice contributions and reinforce constructive behavior.
- Keep inviting dissent so harmony does not become groupthink.
4. Performing: Coordinating Around the Work
A Performing team can direct more energy toward results because purpose, roles, and relationships require less active negotiation. Members adjust to one another, solve problems jointly, and use their different strengths with less friction.
Performing does not mean the absence of conflict or mistakes. It means the team can usually handle them without losing its ability to work. Leadership becomes more flexible: direction is available when needed, but capable members can lead from their expertise.
What helps:
- Protect focus and remove obstacles outside the team's control.
- Keep goals meaningful and performance information visible.
- Encourage experimentation, learning, and honest review.
- Avoid introducing process merely because the team looks self-sufficient.
5. Adjourning: Ending the Work Well
Adjourning occurs when a project ends, a temporary team disbands, or members move into new roles. Attention shifts from producing the work to completing handovers, recognizing contributions, and making sense of the experience.
Endings can bring relief, pride, uncertainty, or loss. Ignoring that transition may leave knowledge undocumented and people feeling that important work simply vanished.
What helps:
- Confirm what is complete and what still needs ownership.
- Document decisions, lessons, contacts, and unfinished risks.
- Recognize contributions without pretending every experience was positive.
- Hold a retrospective and carry useful practices into the next team.
- Provide clarity about what happens next for each member.
Teams Do Not Always Move in a Straight Line
The five stages are a useful map, not a fixed law. Teams may skip a visible stage, move backward, experience several patterns at once, or develop differently depending on the task and context. Tuckman and Jensen's 1977 review itself noted that direct empirical testing of the sequence was limited.
A major change can also restart part of the journey. A new leader, several new members, a changed deadline, or a shift in purpose may bring a previously Performing team back toward Forming or Storming while it renegotiates roles and expectations.
A Quick Team Diagnosis
Ask which challenge currently consumes the team's attention:
- Purpose and roles are unclear: respond as though the team is Forming.
- Differences and power struggles dominate: support the team through Storming.
- Shared habits are emerging: strengthen Norming without suppressing dissent.
- The group coordinates effectively: protect and stretch Performing.
- The work or membership is ending: make space for Adjourning.
The diagnosis matters because the same leadership action can have different effects. More freedom may energize a Performing team but leave a Forming team confused. More structure may help early coordination but frustrate a team that already manages itself well.
Use the Model as a Conversation
Rather than labeling the team from above, invite members to discuss where the model fits and where it does not. Ask what the group needs next: clarity, conflict skills, shared norms, fewer obstacles, or a deliberate ending.
A team stage is not a grade. It is a clue about the kind of support the group may need next.
Tuckman's model remains useful because it makes turbulence less mysterious. A difficult period does not automatically mean the team is broken. It may mean the group is doing the work of turning individual members into a coordinated system.
