Performance management consists of defining goals, assessing performance against those goals, and providing reinforcement. It is influenced by factors like business strategy and employee involvement. Goals should be specific, challenging but attainable. Participation in goal setting increases commitment. Management support and feedback are also important. Management By Objectives involves managers and subordinates jointly setting objectives and action plans. However, MBO can be time-consuming and require strong managerial skills. Performance appraisal evaluates employee performance and is needed for decisions around pay, promotion, development, and planning. The method depends on its purpose and may involve multiple raters. Objectives include career planning, identifying strengths/weaknesses, and training needs.
