The employee who is not certain to whom he reports is never sure of what is expected of him. The manager who countermands orders, or issues new assignments without informing employees, destroys efficiency. In emergencies it may be necessary to step in and take charge. However, the experienced manager does not ignore lines of authority in his rush to get the job done. If you give an employee a hodgepodge of unrelated assignments, you probably will not get optimum performance.
Coordination is a function of management.
In general, it refers to the job of ensuring that the work of one employee contributes to, rather than conflicts or overlaps with, another individual. The essence of homogeneous assignments is that functions required for a particular task should be grouped according to their relation to one another. The abilities of people improve or decline. An effective organization today may be totally inadequate to meet tomorrow's needs. The forward looking manager constantly studies the functioning of his organization so that he can apply quick remedies when he detects weaknesses.
