It helps the organization to rank the employees based on their performance, so that the employer can understand the deficient areas in which the employees need to be trained. Based on the evaluation feedback, the employer can determine which employee will be promoted, retained, retained, or fired. Performance appraisal is one of the most important keys for the human resources department. It helps the organization to determine career goals and devise strategies to achieve the goal and utilize the full potential. These strategies are based on career advice, succession planning, training needs and individual capabilities.

Decisions on certain categories such as salary, promotion, retention/termination, performance recognition, layoffs, and identification of poor performers can be made based on the results. Performance appraisals help organizations clarify individual and organizational expectations and goals.
