Patterns of job requirements.

"This study involved both a factor analysis of job variables and the development of patterns of job requirements in terms of these factors. The major results can be summarized as follows: (a) The factor analysis of 44 variables resulted in the emergence of seven factors that may be thought of as job requirement factors. (b) The classification of jobs into patterns of job requirements (in terms of factor score level) revealed a strong concentration of jobs in a very limited number of the various possible patterns."
