The process of evaluating results against established expectations is:

 Definition of Performance Appraisal: Performance appraisal is a systematic process where employee performance is evaluated against pre-established expectations, such as goals, competencies, and job responsibilities.  Why Performance Appraisal is Correct: It provides a structured approach to assess results, offer feedback, and identify areas for improvement or recognition. This process directly compares outcomes to expectations.  Eliminating Incorrect Options:
A . Gap analysis: Focuses on identifying gaps between current and desired performance at an organizational or process level.
B . Job analysis: Analyzes job duties, not employee performance.
D . Multirotor feedback: Refers to a feedback process involving multiple sources but does not inherently evaluate results against expectations.  International HR Reference: ISO 30414: Encourages structured performance evaluation systems.
