Using field study data collected from 175 line employees and 114 supervisors, from three manufacturing plants in Mexico this study tested hypothesized indirect relations between supervisors' and subordinates' performance at the individual and group levels of analysis. Specifically, declarative knowledge, procedural knowledge and skills, and motivation were examined as mediators of the relationship between two behavioral performance factors within Campbell's (1990) performance taxonomy, Supervision and Facilitating Peer and Team Performance. The results provided partial support for hypotheses involving the mediating role of procedural knowledge and skills and motivation. In addition, correlations between alternate source performance ratings indicated that peers ratings, self-ratings, and supervisory ratings are dissimilar. The implications of these findings for studying and managing performance in organizations are discussed
