This document discusses and compares traditional and modern methods of performance appraisal. It outlines 6 modern methods: assessment centre, appraisal by results (MBO), human asset accounting, behaviorally anchored rating scales (BARS), and 360-degree feedback. For each method, it provides a brief description and highlights their advantages as providing frequent feedback, being more developmental, and grouping rewards organizationally rather than individually. It also notes potential disadvantages like being subjective and a waste of time if not done correctly.
