An approach to isolating dimensions of job success

Abstract

Rational job analyses are deficient in providing a sound basis for development of valid measuring devices. A statistical approach was developed in which (a) supervisors described Airplane and Engine mechanics (selected to vary in proficiency), and (b) a compendium of these descriptions was factor-analyzed. A large number of factors (23) related to job proficiency were extracted. It was concluded that "supervisors describe trained mechanics who are selected by them to vary in proficiency much more in terms of interest and motivation than in terms of the amount of job knowledge possessed."
