The self appraisal process provides unique benefits and serves some specific purposes in the employee performance management process. Including self appraisal in the performance appraisal process can help managers make more accurate performance ratings and conduct productive performance review discussions with employees, if used properly. 1. Self Appraisal Provides Managers with Vital Information for Decision Making The employee performance management process requires managers to review and integrate performance data for a given period of time, analyze the data, and ultimately make decisions regarding ratings. Employee self appraisal is an important source of information on behavior and outcomes that may be missed over the course of the performance period. Performance feedback from peers or direct reports provides unique and specific insight on performance and the same holds true for self evaluation. Self appraisal, coupled with multi-rater feedback, provides a complete picture of performance so that managers can draw accurate conclusions regarding performance ratings.
