The five stages every team moves through
Forming, storming, norming, performing, adjourning. Tuckman's model explained with what actually helps: what defines each stage, what the leader must do, and where teams get stuck.

What the model is good for — and what it is not
Bruce W. Tuckman described four stages of group development in 1965 and added a fifth about closure in 1977. The model became one of the most used languages about teams because it names something everyone has experienced: a new team is not a team yet.
But the model is descriptive, not a staircase you climb once. A team slips back every time the task, the leader or the line-up changes. A new colleague, a new strategy or a round of redundancies often sends a well-functioning team straight back into storming — and that is normal.
The five stages
1. Forming — politeness and uncertainty
Everyone is friendly, nobody is candid. People test what is acceptable to say. The leader must be explicit about purpose, frame and expectations — ambiguity here becomes conflict later.
2. Storming — disagreement surfaces
Roles, ambition and ways of working collide. The danger is not the conflict but suppressing it. The leader must make disagreement legitimate and keep it on the issue rather than the people.
3. Norming — agreements take shape
The group finds its ground rules: who does what, how decisions are made, how feedback is given. Write the agreements down. Unwritten norms only hold until the first new colleague arrives.
4. Performing — the team delivers
Energy goes into the task rather than the relationships. The team corrects its own course. The leader shifts from steering to removing obstacles and protecting focus.
5. Adjourning — closure and learning
The project ends or the team changes shape. Without a proper ending people carry unresolved feelings onwards. Mark the result, harvest the learning, and say it out loud if something did not work.
Where teams typically get stuck
Permanent forming. Everyone is kind, meetings are pleasant, and nobody says what they are thinking on the way out. The team is not aligned — it is just quiet.
Storming without facilitation. Disagreement surfaces, but without a frame it turns personal. After a few rounds people learn that speaking up is not worth it.
Norming that was never written down. The agreements only exist in the heads of those who made them. The next person to join breaks them without knowing.
Performing without maintenance. The team delivers, so nobody looks at the collaboration. When pressure arrives it turns out the roles were never clarified — only worked around.
How to move the team forward
Make the unsaid visible
Let every participant form their own picture of the collaboration before anyone debates it. Then the three loudest voices do not define reality on their own.
Talk to the model, not the person
When criticism points at something on the table rather than at a colleague, people dare to say what they otherwise keep to themselves. That is the whole point of LEGO® SERIOUS PLAY®.
End with agreements, not atmosphere
Write down the five to seven ground rules, put a name and a date on each item, and agree to revisit after 30 and 90 days.
Frequently asked questions about the stages of team development
What is Tuckman's model?+
Tuckman's model describes the stages a group typically moves through before it works as a team. Bruce W. Tuckman described four stages in 1965 — forming, storming, norming and performing — and added a fifth, adjourning, in 1977. It describes patterns rather than a roadmap: teams move back and forth, especially when the task, the leader or the line-up changes.
How long does each stage take?+
There is no fixed duration. A project team on a tight deadline can pass through forming and storming in a week, while a leadership team can stay politely in forming for years because nobody starts the difficult conversation. What matters is not time, but whether the conflicts in storming are talked through instead of avoided.
Which stage is the hardest?+
Storming. This is where disagreement about roles, ambition and ways of working surfaces — and where most teams either grow stronger or learn to stay quiet. A team that has never had an open storming stage has usually just moved the conflict under the table.
How do we know which stage we are in?+
Listen to what is being discussed. If the conversation is about getting to know each other, you are in forming. If it is about who decides what, you are in storming. If it is about how we do things here, you are in norming. If it is mostly about the task and the result, you are in performing.
How does a workshop move a team forward?+
A facilitated day does what everyday work rarely makes room for: every participant forms their own picture of the collaboration before anyone debates it. With LEGO® SERIOUS PLAY® everyone builds their answer, so disagreement becomes visible and concrete rather than personal — and the day ends with agreements, not just a good mood.
