Tuckman’s 5 Stages of Team Development is a model that explains how teams grow and mature. Developed by Dr Bruce Tuckman in 1965, it describes five phases: Forming, Storming, Norming, Performing, and Adjourning that teams pass through on their way to high performance.
Dr Tuckman introduced this model to help leaders and organisations understand team dynamics. He observed that teams follow a predictable path, moving from early uncertainty to strong collaboration. In 1977, he added the fifth stage, Adjourning, to reflect the closure of temporary teams and projects.
The model is widely used in management, HR, and leadership training. For example, project managers apply it to anticipate challenges in team collaboration. Coaches and consultants use it to help teams handle conflict and grow stronger.
Tuckman’s model remains a key tool for understanding teamwork. By recognising the stages, leaders can give the right support at the right time, turning groups of individuals into high-performing teams.
