Abstract

In this study, 360 degree appraisal of the 46 R & D managers, including self, supervisor, peer and subordinates was conducted through the use of rating scales which were based on the competing values model(Quinn, 1988). In the t-test which was done to see if there were any systematic differences among raters, self-rating was higher than the other ratings, except two leadership role dimensions. Especially, self-rating was significantly higher than the supervisor-rating in most leadership role dimensions. However, self-rating was not significantly higher than the subordinate-rating except one dimension(Study 1). In study 2, performance criteria(performance rating and promotion) of the 42 R & D managers were collected, and the correlation analysis was done to see if there were any relationship between 360 degree rating and performance criteria, and if the congruence between self-rating and other ratings would affect the performance criteria. The results showed that there were different relationships in six leadership dimensions. The results of this study was discussed with perceptual or attributional bias.
