This document discusses management by objectives (MBO) performance appraisal. MBO involves setting clear strategic and departmental goals that are then used to review individual performance results. While MBO has been widely discussed since the 1950s, surveys find that less than 10% of firms regard their MBO system as very successful. MBO implementation varies between organizations in terms of whether objectives are set for the whole organization or sub-units, and how manager and subordinate participation is approached. Effective MBO requires managers to have clearly defined objectives that contribute to overall company goals, and for subordinates to help set objectives at higher management levels.
