Coordination is the process of linking activities between departments that are interdependent on each other for resources and information. It provides unity of action toward a common purpose through orderly arrangement of group effort. Coordination is a managerial responsibility at all levels of management that is continuous, dynamic, and necessary for effective group efforts through pooled, sequential, or reciprocal interdependence. It can be achieved through rules and procedures, hierarchy, planning, liaison roles, task forces, and coordination departments.
