Management by Objectives (MBO) is a systematic process for setting performance goals and monitoring results. It was first outlined by Peter Drucker in 1954 and involves employees participating in goal setting for their roles. The key principles of MBO are aligning individual, team and organizational goals and providing ongoing feedback to achieve objectives. MBO aims to increase motivation, communication and performance by clarifying expectations. However, it requires objectives be carefully set and monitored to avoid unintended outcomes.
