Psychologist Bruce Tuckman first came up with the memorable phrase "forming, storming, norming and performing" back in 1965. He used it to describe the path to high-performance that most teams follow. Later, he added a fifth stage that he called "adjourning" (and others often call "mourning" – it rhymes better!)
Teams initially go through a "forming" stage in which members are positive and polite. Some members are anxious, as they haven't yet worked out exactly what work the team will involve. Others are simply excited about the task ahead. As leader, you play a dominant role at this stage: other members' roles and responsibilities are less clear.
This stage is usually fairly short, and may only last for the single meeting at which people are introduced to one-another. At this stage there may be discussions about how the team will work, which can be frustrating for some members who simply want to get on with the team task.
Soon, reality sets in and your team moves into a "storming" phase. Your authority may be challenged as others jockey for position and their roles are clarified. The ways of working start to be defined and, as leader, you must be aware that some members may feel overwhelmed by how much there is to do, or uncomfortable with the approach being used. Some may react by questioning how worthwhile the goal of the team is, and by resisting taking on tasks. This is the stage when many teams fail, and even those that stick with the task may feel that they are on an emotional roller coaster, as they try to focus on the job in hand without the support of established processes or relationships with their colleagues.
Gradually, the team moves into a "norming" stage, as a hierarchy is established. Team members come to respect your authority as a leader, and others show leadership in specific areas.
Now that the team members know each other better, they may be socializing together, and they are able to ask each other for help and provide constructive criticism. The team develops a stronger commitment to the team goal, and you start to see good progress towards it.
There is often a prolonged overlap between storming and norming behavior: As new tasks come up, the team may lapse back into typical storming stage behavior, but this eventually dies out.
When the team reaches the "performing" stage, hard work leads directly to progress towards the shared vision of their goal, supported by the structures and processes that have been set up. Individual team members may join or leave the team without affecting the performing culture.
As leader, you are able to delegate much of the work and can concentrate on developing team members. Being part of the team at this stage feels "easy" compared with earlier on.
Project teams exist only for a fixed period, and even permanent teams may be disbanded through organizational restructuring. As team leader, your concern is both for the team's goal and the team members. Breaking up a team can be stressful for all concerned and the "adjourning" or "mourning" stage is important in reaching both team goal and personal conclusions.
The break up of the team can be hard for members who like routine or who have developed close working relationships with other team members, particularly if their future roles or even jobs look uncertain.
