Teams are defined as small groups of people with complementary skills committed to a common purpose and goals for which they hold each other mutually accountable. There are several types of teams including self-managed teams, task forces, cross-functional teams, and virtual teams. Factors that influence team effectiveness include team design elements like task characteristics, size, and composition as well as team processes like development, norms, roles, and cohesiveness. Highly cohesive teams with norms that support organizational goals tend to have higher performance while social loafing can negatively impact team performance.
