Coordination involves synchronizing group efforts to accomplish goals. It harmonizes individual efforts. Proper coordination ensures departments work harmoniously, are informed of tasks, and adapt to changes. Coordination techniques include supervision, communication, contact, delegation, and liaison. Departments sometimes isolate themselves without considering others, while employees lack initiative. Managers must identify external forces like customers, employees, policies, technology, and environment to analyze impacts and respond appropriately. Principles of effective coordination are early planning, contact at all levels, recognizing interdependence, and continuous information exchange.
