The document discusses various methods for performance appraisal in organizations. It describes trait-based, behavior-based, knowledge/skill-based, and result-based approaches. Each method is explained along with its advantages and disadvantages. Trait-based appraisals are simple but subjective. Behavior-based appraisals provide specific feedback but take more time. Knowledge/skill appraisals measure competencies but not always job application. Result-based appraisals link performance to goals but can encourage short-term thinking. The document also reviews sources of appraisal like subordinate, peer, customer, and team evaluations.
