Management by exception states that management should "

Give attention to significant deviations only. Accept exceptions in emergencies. Check everything without exception. Invariably take corrective action without exception.

Give attention to significant deviations only.

Management by Exception: Management by exception, which is often referred to as control by exception, is an important principle of management control based on the belief that an attempt to control everything results in controlling nothing. Thus, only significant deviations which go beyond the permissible limit should be brought to the notice of management. Thus, if the plans lay down 2 per cent increase in labour cost as an acceptable range of deviation in a manufacturing organisation, only increase in labour cost beyond 2 per cent should be brought to the notice of the management. However, in case of major deviation from the standard (say, 5 per cent), the matter has to receive immediate action of management on a priority basis.
