Management by Objectives (MBO) is a technique where managers and employees work together to set goals for a specific period of time. Organizational goals flow top-down and are translated into personal goals for employees. The technique was first championed by Peter Drucker in the 1960s. MBO helps employees understand their duties, sets clear expectations, and leads to motivated employees through effective communication and periodic performance reviews. However, limitations include that it may ignore workplace culture and conditions, increase comparisons between employees, and lack innovation if employees only do what is asked.
