A successful team completes its task, maintains good social relations, and promotes its members' personal and professional development. All three of these factors are important for defining team success.

nature of team success
According to Hackman (1987), there are three primary definitions of team success, relating to the task, social relations, and the individual. A successful team completes its task or reaches its goals. While completing the task, team members develop social relations that help them work together and maintain the group. Participation in teamwork is personally rewarding for the individual because of the social support, the learning of new skills, or the rewards given by the organization for participation. P19

Group norms P48

Group norms are the ground rules that define appropriate and inappropriate behavior in a group. They establish expectations about how group members are to behave.

There are four main functions of group norms (Feldman, 1984). First, group norms express the group's central values, which help give members a sense of who they are as a group. Second, norms help coordinate the activities of group members by establishing common ground and making behavior more predictable. Third, norms help define appropriate behavior for group members, allowing members to avoid embarrassing or difficult situations, thereby encouraging active participation in the group. Fourth, norms help the group survive by creating a distinctive identity; this identity helps group members understand how they are different from others and provides criteria for evaluating deviant behavior within the group.
