A performance appraisal is a formal interaction between managers and their employees where the employees are evaluated during a set time span to determine their weaknesses and strengths. The main objectives of performance appraisal are correcting weaknesses observed in employees, encouraging their strengths, and providing them an opportunity for professional development. The appraisals provide vital information used for transfers, promotions, and wage increment. As such, the management should ensure that organization’s appraisal system is unbiased, ensures free flow of information, and is in line with organization’s objectives. According to DelPo (2007) there are two main categories of performance appraisals, individual and multiple person appraisal systems. Under the individual appraisal system, employees’ performance is studied in terms of their strengths and weaknesses over a given time period. The popular forms of this performance appraisal system include, Management by Objectives, Annual Confidential Reports, Checklist, and Critical incident. These forms are discussed detail below.

To achieve these goals, the management identifies the key result areas and develops strategies to attain the best results. This information is passed to the employees who then work as a team to help achieve the set goals. The Multiple Persons Appraisal Methods This type of performance appraisal compares employees’ performance against each other. It is categorized into, ranking, performance tests, paired comparison, and 360 Degree. 360-Degree Appraisal Method 360-Degree is an all round appraisal method. This is because all the persons with whom the employee interacts while performing work duties provide the information or data used in his or her appraisal. This means that all the aspects of an employee’s performance and personality are analyzed since every person evaluates based on his or her own view. The employee under evaluation gets the results of the exercise to help him or her increase performance. Paired Comparison Method In this method, the management compares employees to one another on basis of performance and personality traits. He then ranks th
