A factorial approach to job families.

This is an experimental study of the application of factor analysis to a new domain-the formation of job families. Correlations between jobs are computed from the formula based on the number of common elements between two variables and the job analyses provide £he basic data on the presence or absence of the elements. A firstorder general factor and four common factors are obtained in a small sample of twenty occupations. Tentative interpretations are made and implications for job analysis and the formation of job families are pointed out.
