It is often advised that, in a quest to control everything, it may often result in controlling nothing. Which concept of management is being referred to here?

Option 1 -> Management by perfection is not a recognized management concept and doesn't address the principle of selective control based on significance.

Option 2 -> Task management focuses on organizing and executing individual tasks, but doesn't relate to the principle of avoiding excessive control over routine matters.

Option 3 -> Management by exception is the practice where managers focus only on significant deviations from normal operations rather than monitoring every detail, allowing routine matters to proceed without intervention.

Option 4 -> Impoverished management refers to a leadership style with low concern for both people and production (Blake-Mouton Grid), not related to selective control principles.

Hence, Option 3: Management by exception -> This concept recognizes that attempting to control every aspect of operations dilutes management attention and resources. By focusing only on significant exceptions or deviations from expected performance, managers can effectively control what truly matters while allowing routine operations to function smoothly without constant oversight -> correct
