Question Answer
Groups & Types of Groups Two or more interacting and interdependent individuals who collaborate to achieve specific goals. Formal group: A group defined by an organisation’s structure Informal group: A group that is neither formally structured nor organisationally determined that members voluntarily join because they derive personal benefits, share a common interest or pursue similar goals
Reasons Why People Join Group People join groups for a variety of reasons that are generally related to their drive to satisfy social, power, achievement and other personal needs. 1. Similarity: around those who share the same values or characteristics 2. Distinctiveness: show that they are different 3. Status: identify & associate themselves with high-status groups 4. Uncertainty reduction: want to better understand who they are and their role in the world
Tuckman’s 5 Stage Group Development Model 1. Forming: uncertainty about the group’s purpose, structure, and leadership. Members try to determine what types of behaviour are acceptable. 2. Storming: Characterised by intra-group conflict. Members accept the existence of the group, but there is resistance to constraints on individuality. 3. Norming: Characterised by close relationships and cohesiveness. The group structure solidifies and the group has a common set of expectations for what defines correct member behaviour. 4. Performing: The group structure at this point is fully functional and accepted. Group is focused on performing the task at hand. 5. Adjourning: For temporary groups, the group prepares for its disbandment, wrapping up activities.
