MBO is a comprehensive managerial system for setting goals and evaluating performance based on accomplishing those goals. The goals must be mutually agreed upon by employees and supervisors, challenging but achievable, within an employee's control, and reviewed periodically for modifications. The MBO process involves setting organizational objectives and key result areas, establishing subordinate objectives, matching resources to objectives, performance appraisal, and recycling the process. Benefits include better management through clarity of objectives and roles, periodic feedback, and participation in management. Problems can arise from difficulties setting goals, failure to teach the MBO philosophy, issues with objective setting, overemphasis on short-term goals, and potential for frustration.
