During which stage of group development is the mission of the group typically developed?

The stage of group development where the mission of the group is typically developed is the forming stage. During this initial phase, team members come together and start to understand the group's objectives and purpose. This stage involves introducing members to one another, establishing ground rules, and beginning to explore the group's mission and goals.

In the forming stage, individuals may still be getting to know each other and are often polite and reserved. As they interact, they begin to lay the foundation for the group's collective purpose, which can be further refined as the group moves into subsequent stages. The development of a clear mission is essential as it provides direction and alignment for the group as it progresses through the later stages, such as storming, norming, and performing, where members begin to define roles, establish norms, and engage in team activities based on the mission established.
