Controlling is forward looking as it must focus attention on two things checking current performance and providing early information to achieve results in conformity with set standards. Checking on operations should enable prompt detection of faults before it is too late for remedy. Deviations, if any, should lead to investigation of the factors responsible which may affect future operations. Remedial actions should be followed so as to prevent the occurrence of defects thereafter. In other words, control must ensure timely detection of deviations and prevention of their repetition in future.
