Potential appraisal is a process used to determine an employee's strengths and weaknesses to predict future performance. This helps identify employees suitable for higher positions and assists in career planning. Potential appraisals are necessary because past performance may not indicate suitability for new roles. They inform employees of career prospects, help organizations plan succession, and guide employee development. An effective potential appraisal system clearly defines roles and required qualities, uses rating mechanisms like supervisor ratings, tests, and simulations, and provides feedback to employees.
