Supervision involves overseeing employees' work through guidance, teaching, and evaluation. It aims to help subordinates perform their tasks better by training, educating, guiding and counseling them. Supervision can be direct through face-to-face interaction or indirect using records and reports. The purposes of supervision include inspecting work, evaluating performance, promoting motivation and teamwork, and bridging gaps between personal and organizational goals. A good supervisor establishes clear performance criteria, provides feedback, encourages participation, respects subordinates, and helps staff grow in their roles.
