“…Models have been developed in the areas of job design (e.g., Wong and Campion, 1991) and socio-technical systems (e.g., Bendoly et al, in press;Huber and Brown, 1991) that specifically address the human factors of work systems, and how variation in performance interacts with the task itself. However, except for the recognition that individual differences are a major cause of work-rate variability (Dudley, 1968;Knott and Sury, 1987;Salvendy and Stewart, 1975;Juran and Schruben, 2004), little has traditionally been done to incorporate individual differences into OM research. This has changed recently with the work of Bartholdi and Eisenstein (2005), , and Zavadlav et al (1996).…”
