Controllability Concept

The controllability concept in accounting and management refers to the idea that managers should be evaluated and held accountable only for the costs and investments over which they have direct control. This principle is designed to ensure fairness and accuracy in performance measurement by attributing responsibility to the appropriate level of management.
