This document discusses teams and teamwork. It defines a team as a small group of people with complementary skills committed to a common goal for which they hold each other mutually accountable. Teamwork is essential in modern organizations. For a work group to become an effective team, leadership must be shared, accountability must shift to both individual and collective levels, the group must develop a shared purpose or mission, and problem solving must be an ongoing activity. There are four main types of teams: advice teams, production teams, project teams, and action teams. Cooperation, trust, and cohesiveness are important factors for effective teamwork.
