“…Many of these studies were undertaken primarily to illustrate particular grouping strategies, job analysis methods, or measurement techniques that might prove useful as means of constructing job families (cf.

Some researchers have developed job family systems for purposes of model or theory development within specified areas of research (cf.…”
