Every department in an organisation function independently. But the activities of one department influence those of another department. For example, the activities of the purchase department influence those of the production department and vice versa. Thus, it reveals that the various departments in an organisation are inter-related and inter-dependent. Coordination is a management function in which it acts as a link between the activities of different departments. Every department has its own objective. Coordination ensures that all the departments contribute to the attainment of the goal of the whole enterprise.
From the above diagram, it has clearly revealed that the way coordination links planning, organising, staffing, directing and controlling. Besides, the concept lies with the attainment of organisation objectives.
