Forming - formalities are preserved and members are treated as strangers.
Storming - members start to communicate their feelings but probably still view themselves as part of their parent department rather than part of the team. They attack others insular attitudes while guarding their own.
Norming - people feel part of the team and realise that they can achieve work if they accept other viewpoints.
Performing - the team works in an open and trusting atmosphere where flexibility is the key and hierarchy is of little importance.
