Group generally passes through a standardized sequence in their evolution. This sequence is called five-stage model of group development. Although all groups do not follow this sequence research provide a useful framework for understanding group development. These stages are briefly described below:
1. Forming stage: Forming is the first stage of group development, characterized by a great deal of uncertainty about the purpose, structure and leadership of the group. This stage determines what types of behaviors are acceptable. And this stage is completed when members think themselves as a part of the group.
2. Storming stage: It is the second stage of group development, characterized by intra-group conflict. In this stage members accept the existence of group but there is a conflict over who will lead and control the group. It provides a clear hierarchy of leadership within group.
3. Norming stage: This stage of group development is characterized by close relationship and cohesiveness. There is a strong sense of group identity and friendship among group members. It provides a group structure and a common set of expectations.
4. Performing stage: In the performing stage the group becomes fully functional and acceptable to all group members. Here group members know and understand each other. In case of permanent work groups, performing is the last stage of group development.
5. Adjourning stage: It is the last stage of group development for temporary group. This stage emphasizes on wrapping up activities rather than task performance. In this stage group prepares for its disbandment.
