What is the difference between performance appraisal and competency mapping?

Performance  evaluation is a know how and  skill  level of all team members  . The  Map of  efficiency at  work  is  the  development and identify people with  good skills in  the best places to work and  improve the  level of  achievement .

Performance appraisal is a process in which we evaluate, judge, measure or estimate performance reference to predefined performance standards such as goals, objectives, achievement targets and competencies with identified proficiency level while competency mapping is the process of identifying and framing competencies for a specific job or role. Competency mapping tell us what are the job required competencies (knowledge, skills and abilities) and what are the proficiency levels for each competency regardless of the job occupant. Competency mapping will guide how the job will be done and performance appraisal measure how the employee performed in carrying the job tasks and achieving the goals and objective.
