Which appraisal system would you recommend to your organization for appraising its employees and why?
I would recommend 360-degree feedback, i.e., in human resources or industrial/organizational psychology, also known as multi-rater feedback, multisource feedback, or multisource assessment; because it is the feedback that comes from all around an employee. "360" refers to the 360 degrees in a circle, with an individual figuratively in the center of the circle. Feedback is provided by subordinates, peers, and supervisors. It also includes a self-assessment and, in some cases, feedback from external sources such as customers and suppliers or other interested stakeholders. It may be contrasted with "upward feedback," where managers are given feedback by their direct reports, or a "traditional performance appraisal," where the employees are most often reviewed only by their managers.
