Determining the best appraisal method or form to use depends on the objectives of the organization. A combination of the methods and forms is usually superior to any one used by itself. For developmental objectives, the critical incidents, MBO, and narrative methods work well. For administrative decisions, a ranking method based on the evaluative methods and especially graphic rating scale or BARS forms works well. In my opinion, the best performance appraisal model is 360 degree feedback because they prefer more to the peers.
