Group Formation and Team Development: Tuckman's Stages for ACCA BT

Updated 11 October 2026 · Fact-checked

A group is two or more people who interact and share a common interest. A team is a group with a shared goal and complementary skills. Tuckman says groups develop through forming, storming, norming and performing, with adjourning added later. To answer questions, match the behaviour described to the stage.

Understand Group Formation and Team Development

A group is a number of people who interact, are aware of each other and see themselves as part of the same unit. A queue is not a group. People in one department usually are.

A team is a type of group. Team members share a common goal, depend on each other and bring different skills. All teams are groups, but not all groups are teams. A group of staff who just work in the same office may share nothing beyond a manager.

Groups can be formal or informal. Formal groups are set up by the organisation to do a task, such as a project team or a department. Informal groups form on their own because people like each other or share interests, such as a lunch group. Informal groups can help or harm the organisation. Other types you may see include permanent and temporary groups, and virtual teams that work across locations through technology.

People join groups for many reasons. They want to belong, to feel safe, to share tasks, to gain status, to get support, or to reach goals they could not reach alone. Organisations create groups because teams can share skills, produce better ideas and spread workload.

Tuckman described how a new group develops over time:

Forming: members meet, are polite and unsure. They look to the leader for direction.
Storming: disagreement appears over roles, goals and leadership. Conflict and power struggles are common.
Norming: members agree rules, roles and ways of working. Cooperation and trust grow.
Performing: the group works well together and focuses on the task. Roles are flexible.
Adjourning: added later. The task ends and the group breaks up.

Not every group reaches performing. Some stay stuck in storming. A change of members can send a group back to an earlier stage.

Key formulas to remember

Group versus team: Group = people who interact and see themselves as a unit; Team = group + shared goal + complementary skills; Every team is a group, but not every group is a team.
Tuckman's stages: Forming → Storming → Norming → Performing (→ Adjourning); Adjourning was added by Tuckman later. Learn the order exactly.
Formal versus informal groups: Formal = created by the organisation for a purpose; Informal = created by members through social needs; Informal groups can support or work against organisational goals.

How to solve Group Formation and Team Development questions

Use this method for any question on groups, teams or Tuckman.

1Read the question and decide whether it asks for a definition, a type of group, a reason for forming, or a stage of development.
2If it is about a definition, check for a shared goal and complementary skills. These point to a team rather than a group.
3If it is about a type, check who created the group. The organisation means formal. The members themselves means informal.
4If it is about a stage, find the key behaviour in the scenario: politeness, conflict, agreement on rules, or strong output.
5Match the behaviour to the stage: polite and unsure is forming, conflict is storming, rules and trust is norming, effective work is performing, breaking up is adjourning.
6For multiple response questions, select exactly the number stated and check each option separately.
7Re-read the question to confirm you answered what was asked.

Quickest way: Keyword matching for Tuckman and groups

When to use it: Use this in Section A objective test questions when you have under a minute per question.

Scan the scenario for one clue word: polite, conflict, rules, productive, disband.
Link it: polite = forming, conflict = storming, rules = norming, productive = performing, disband = adjourning.
For group versus team, look for shared goal and complementary skills. If present, it is a team.
Eliminate options that describe a different stage, then choose the one left.

Common mistakes in Group Formation and Team Development

Treating group and team as the same thing.
In daily speech the words are used interchangeably.
Fix: Remember a team needs a shared goal and complementary skills. A group may only share a location or manager.
Putting the stages in the wrong order, such as norming before storming.
Students pick the order that sounds more pleasant.
Fix: Use the order Forming, Storming, Norming, Performing. Conflict comes before agreement.
Thinking storming means the group has failed.
Conflict seems negative.
Fix: Storming is a normal stage. Handled well, it clarifies roles and goals. Some groups never get past it, but it is not a sign of failure by itself.
Assuming every group reaches performing.
The model looks like a fixed path.
Fix: Groups can stall or move back, for example when a member leaves or a new one joins.
Calling an informal group harmful or useless.
Students link informal with unofficial and unwanted.
Fix: Informal groups meet social needs and can improve communication and morale. They can also resist change.
Forgetting adjourning or confusing it with storming.
It was added later and is not in the classic four-stage list.
Fix: Adjourning is the end of the group when the task is done. Learn it as the fifth stage.

Worked examples

Example 1

A new project team has just been formed. Members are polite with each other, ask the manager many questions and are unsure of their roles. Which stage of Tuckman's model is the team in? A Forming B Storming C Norming D Performing

Show the solution

Identify the clues: polite behaviour, reliance on the manager, unclear roles.
Recall that forming is the first stage, where members are unsure and dependent on the leader.
Storming would show open disagreement, norming would show agreed rules, and performing would show effective output. None of these fits.

Answer: A Forming

Example 2

Explain the difference between a group and a team, and state one reason why people join groups.

Show the solution

Define a group: two or more people who interact and see themselves as part of a unit.
Define a team: a group whose members share a common goal and bring complementary skills, relying on each other.
State the link: every team is a group, but a group of people who just share an office is not necessarily a team.
Give a reason for joining: people join groups to meet needs such as belonging, support, security or status.

Answer: A group is people who interact and see themselves as a unit. A team is a group with a shared goal and complementary skills. People join groups to meet needs such as belonging and support.

Exam tips

Section A questions often give a short scenario and ask for the Tuckman stage. Find the behaviour clue first, then choose the option.
Know the order of stages exactly. Examiners test sequence directly.
For group versus team questions, look for shared goal and complementary skills.
In multiple response questions, select exactly the stated number of options. Do not add extras.

Practice questions from Individual and group behaviour in business organisations

Group Formation and Team Development: frequently asked questions

What is the difference between a group and a team?

A group is people who interact and see themselves as a unit. A team is a group with a shared goal and complementary skills, who depend on each other. All teams are groups, but not all groups are teams.

What are Tuckman's stages of group development?

The stages are forming, storming, norming and performing. Adjourning was added later for when the group breaks up. Each stage has typical behaviour, such as politeness in forming and conflict in storming.

Does every group reach the performing stage?

No. Some groups stay in storming or break up before they perform well. A change in membership or task can also send a group back to an earlier stage.

Why do people form or join groups?

People join groups to belong, feel secure, get support, share work, gain status or achieve goals they could not reach alone. Organisations also create groups to combine skills and ideas.
