Performance appraisal (PA) is used to evaluate employee performance and potential. It involves both quantitative and qualitative assessments of an employee's job performance over a period of time. PA helps identify employee strengths and weaknesses, set goals, determine training needs, and inform compensation and promotion decisions. Effective PA systems include clear objectives, standardized processes, training for managers, job-related evaluations, documentation, feedback opportunities, and post-appraisal reviews. Traditional methods include graphic rating scales, rankings, and checklists. Modern methods include behavioral anchored rating scales, 360-degree feedback, and management by objectives.
