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. Key factors that enable coordination include clearly defined objectives, effective chains of command, group meetings, harmonious policies, sound organizational structure, leadership, and incentives.
