Work teams and groups

Work teams and groups form the operational structure of many organizations. A workgroup is a collection of two or more people who interact with one another and share some interrelated task goals. A work team is a type of workgroup, but a team has three specific properties, 1) the actions of individuals must be interdependent and coordinated, 2) each member must have a particular, specified role. 3) there must be common task goals and objectives.
