Abstract
Traditional ergonomics has concentrated on improving such metrics as productivity, health, safety, and quality of work life. While such local improvements are important, increasingly, there is pressure upon ergonomists to achieve global improvement. This article reviews some of the basic concepts behind large‐scale change and takes the position that the macroergonomist is postured uniquely to induce and manage positive change in industrial organizations. While ergonomists focus at the human–machine interface level, organization‐intervention consultants typically focus at the organizational level. Macroergonomists uniquely concentrate their efforts at both levels. © 2004 Wiley Periodicals, Inc. Hum Factors Man 14: 101–115, 2004.
