There are various types of performance appraisals in human resource management. One of them is the 360-degree method which collects feedback from employees from a 360-degree view of everyone they work with. From subordinates to supervisors to customers - you can get the full scoop on their work performance. The second example is the graphic rating scale where employees are rated on a numbered scale in terms of their role's desired personality traits and behavior and how well they match it.
