The Forming – Storming – Norming – Performing model of group development was first proposed by Bruce Tuckman in 1965, who maintained that these phases are all necessary and inevitable in order for the team to grow, to face up to challenges, to tackle problems, to find solutions, to plan work, and to deliver results. This model has become the basis for subsequent models.
Forming: a group of people come together to accomplish a shared purpose.
Storming: Disagreement about mission, vision, and approaches combined with the fact that team members are getting to know each other can cause strained relationships and conflict.
Norming: The team has consciously or unconsciously formed working relationships that are enabling progress on the team’s objectives.
Performing: Relationships, team processes, and the team’s effectiveness in working on its objectives are synching to bring about a successfully functioning team.
Transforming: The team is performing so well that members believe it is the most successful team they have experienced; or
Ending: The team has completed its mission or purpose and it is time for team members to pursue other goals or projects.
