Data was collected on 74 professional and managerial jobs using the Position Analysis Questionnaire (PMPQ). In the first study a principal components analysis was performed with eight principal components being selected for rotation and interpretation. These components were compared to the original ten components found in the developmental study. This comparison revealed a high degree of congruency between the two sets of components. In the second study expert raters attempted to reliably translate job descriptions based on PMPQ data into the task-oriented functions of People, Data, and Things used by the Dictionary of Occupational Titles. The results indicated that raters could not do this, thus highlighting the differences between worker- and task-oriented job analysis procedures. The advantages and disadvantages of principal components analysis and ideas for future lines of research are discussed.
