Can you describe what team effectiveness is?

Team effectiveness (also referred to as group effectiveness) is the capacity a team has to accomplish the goals or objectives administered by an authorized personnel or the organization. A team is a collection of individuals who are interdependent in their tasks, share responsibility for outcomes, and view themselves as a unit embedded in an institutional or organizational system which operates within the established boundaries of that system. Teams and groups have established a synonymous relationship within the confines of processes and research relating to their effectiveness (i.e. group cohesiveness, teamwork) while still maintaining their independence as two separate units, as groups and their members are independent of each other's role, skill, knowledge or purpose versus teams and their members, who are interdependent upon each other's role, skill, knowledge and purpose.

Team effectiveness is the capacity a team has to achieve the goals set for that team. Teams are considered more or less effective based on their ability to achieve their goals and objectives. Teams are comprised of individuals who are interdependent in their tasks, share responsibility for outcomes, and view themselves as a unit embedded in an institutional or organizational system which operates within the boundaries of that system.
