Performance management is defined as a continuous process of identifying, measuring, and developing employee performance and aligning it with organizational goals. It differs from performance appraisal which is typically done once a year without ongoing feedback. Performance management contributes to employees through clearer expectations and feedback, increased motivation and self-esteem, and development opportunities. It contributes to managers through better communication and insight into employee performance. For organizations, it clarifies goals and facilitates change. Performance is determined by declarative knowledge, procedural knowledge, and motivation. It has both task-related and contextual dimensions. Performance can be measured through trait, behavior, and results approaches. The behavior approach assesses how work is done while results assess outcomes produced.
