One of the management functions is

• A. Preparation
• B. Evaluation
• C. Controlling
• D. Revising

Answer: (C)

Controlling is the management function that keeps performance on track by measuring results, comparing them with the plan, and taking corrective action as needed. It closes the loop between what was intended and what is happening, ensuring goals are met and resources are used effectively. For example, a department monitors response times or completion rates; when data show deviations from targets, leaders adjust procedures, reallocate resources, or modify standards to bring performance back in line with objectives.

Preparation aligns with planning—setting up what will be done—so it isn’t the function that manages ongoing performance. Evaluation is part of the ongoing monitoring and review process but isn’t typically named as a separate main function. Revising happens as part of updating plans or responses after review, rather than standing alone as the primary management function.
