Management by objective (MBO) is a process defined by Peter Drucker in 1954 where specific objectives are set within an organization and communicated to employees. The process involves 1) setting organizational goals, 2) establishing employee goals and deciding how they will achieve objectives, 3) monitoring progress, 4) evaluating performance, and 5) rewarding employees. Regular evaluation and monitoring of employee progress is important for the effectiveness of MBO in providing structure and additional performance.
