Step-by-step explanation:
The stage in which groups share ideas and form goals is called forming. This stage is the first in the process of group development and is often characterized by members getting to know one another and beginning to understand the group's purpose. This is distinct from the other stages such as storming, where conflicts arise; norming, where resolution and unity begin to emerge; and performing, where the group is fully functional and working towards their goals.
