Which group growth stage involves task definition primarily?

The growth stage that primarily involves task definition is the forming stage. During this initial stage of group development, members come together and start to understand the group’s dynamics, roles, and goals. This is the phase where the groundwork is laid for task definition, as members begin to identify the group's objectives and outline how they will work together to achieve them.

In this stage, members are often polite and focused on establishing relationships, which allows them to clarify tasks, set expectations, and understand what is required of each individual to contribute effectively to the group's mission. Establishing a foundation of clear tasks is crucial at this point, as it paves the way for the group to move on to the next stages of development.

The subsequent stages, like storming, norming, and performing, are more concerned with the resolution of conflicts, establishment of norms, and effective collaboration, respectively. Therefore, the focus on task definition is a distinctive characteristic of the forming stage.
