A team goes through various stages of development, according to Tuckman and Jensen (1977):

• Forming: pre-team stage where people still work as individuals.
• Storming: the team becomes more aggressive and challenges existing rules or constraints.
• Norming: when the team works out how best to use its resources to carry out the task.
• Performing: the team is working at its optimal best.
• Adjourning (or mourning): the team disbands and individuals move on.
