Performance appraisals are often resented by both managers and subordinates. Managers dislike criticizing subordinates and making judgments about personal worth, while subordinates feel their fate is being decided by those who lack expertise. However, performance appraisals are necessary to ensure employees are acting in the organization's best interests and meeting productivity standards. When done effectively, with commitment from top management and proper training, performance appraisals can motivate employees, improve productivity, and help organizations make strategic decisions. However, many existing performance appraisal systems are poorly designed and do not provide appropriate data for human resource decisions.
