Work groups are a common arrangement within today's business organizations.
Work is being restructured around groups in thousands of organizations. Managers need an understanding of group behavior and the concept of teams in order to appreciate what groups can and cannot do within organizations. Groups exhibit different behavior, more than just the sum total of each group member's individual behavior. A group is defined as two or more interacting and interdependent individuals who come together to achieve particular objectives. Formal groups are work groups established by the organization and have designated work assignments and established tasks.
