Designing the cell operator's job, seen as being very important for the success of computer integrated manufacturing (CIM), has been the responsibility of the manufacturing engineer. Though operator motivation has been seen as important, past studies of supervisors and their subordinates have shown that supervisors are unable to predict the importance of elements of job enrichment to their subordinates. Therefore, it was questionable whether engineers could predict the level of desire of the operators for the elements. The problems of this study were (a) determining elements of job enrichment and their levels of importance to cell operators, (b) determining predictions of engineers of the importance of the elements to operators, and (c) determining if there were significant differences between the views of operators and engineers. The purposes of this study were (a) to establish an information base on elements of job enrichment for cell operators and (b) to encourage engineers to consider motivational information in job design. Using a revised Job Diagnostic Survey (RJDS) and a revised Job Rating Form (RJRF), cell operators and manufacturing engineers were surveyed by mail. It was found that engineers had a significant inability to predict the level of desire for 9 of the 11 potential elements of job enrichment (p $<$.01 for seven items, p $<$.02, and p $<$.05). Importantly, views of would like growth need strength were found to be significantly different (p $<$.01) between engineers and operators. Predictions of core job characteristics were similar. Predictions of Motivating Potential Score (MPS) were found to be significantly different (p $<$.01). Apparent inconsistencies between the engineers' ability to predict core job characteristics and their inability to predict would like growth need strength and the MPS were attributed to two study resultants. First, engineers' appreciated the need to motivate the operators. Secondly, however, engineers did not appreciate their roles in facilitating that motivation through job design. It was concluded that engineers need help from job enrichment specialists in designing jobs.
