Roles Roles and norms play a very important part in group dynamics. A role is a socially determined way of behaving in a specific position. The concept of the role involves others expectations for a central person's behavior in a specific position.  In other words, individuals who occupy certain positions in the group generally perform certain types of behaviors. The follower, the socioemotional specialist, and the task specialist are all typical roles that can evolve in groups through role differentiation, although group members can still experience role conflict if they occupy incompatible roles or the demands of a single role are contradictory.

Norms  The rules that describe the actions that should be taken by group members are known as norms.  Norms are general standards of conduct for various social settings.  Norms have a broader influence than do roles, which focus on a specific position. Norms can be enforced to facilitate survival of the group, to simplify or clarify role expectations, to help group members avoid embarrassing situations, to express key group values, and enhance the  group`s unique identity.

Trust  Trust is another key element in group dynamics.   Trust   is defined as belief in the integrity, character, or ability of others.  Managers can build trust by communicating openly and supporting their employees.  They should show respect through delegation and listening.  To build trust, managers should also be fair, behave predictably, and be competent.
