Management by objectives (MBO) is a systematic process for setting objectives that provide direction and help achieve organizational and individual goals. Key aspects of MBO include formulating clear and measurable objectives, setting objectives at all levels of the organizational hierarchy from board to individual employees, and reviewing objectives periodically with feedback to evaluate progress and make adjustments. For MBO to be effective requires top management support, training employees in MBO, ensuring objectives are clear, providing feedback, and encouraging participation in setting objectives.
