This book presents a nontechnical, step-by-step process that shows how to evaluate any 360-degree-feedback instrument intended for management or leadership development. The 360-degree-feedback instruments collect information from different sources about a target manager's performance, and they offer multiple perspectives. The 16 steps in evaluation are: (1) finding out what is available; (2) collecting a complete set of materials; (3) comparing the intended use to instrument characteristics; (4) examining the feedback scales; (5) familiarizing oneself with the instrument development process; (6) learning how items and feedback scales were developed; (7) finding out how consistent scores tend to be; (8) assessing basic aspects of validity (whether the instrument measures what it claims to measure); (9) thinking about face validity; (10) examining the response scale; (11) evaluating the feedback display; (12) understanding how breakout of rater responses is handled; (13) learning what strategies are used to facilitate interpretation of scores; (14) looking for development and support materials; (15) comparing cost (value for the price); and (16) considering length a minor issue. At the end of the report, there are a checklist of the steps, a glossary of technical terms, and a list of suggested readings. (Contains 12 references.) (SM)
