Computer programs emerge as the outcome of complex human processes of cognition, communication and negotiation, which serve to establish the meaningful embedding of the computer system in its intended use context.

Rosa, Roger R., Monk, Timothy H., Bonnet, Michael H., Eastman, Charmane, Tepas, Donald I., Bootzin, Richard R., Walsh, James K. and Duchon, James C. (1988): Designing Shift Work Systems to Improve Performance and Alertness: What Do We Know and What Do We Need to Know?. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 727-728.

Approximately 20% of the full-time non-farm workforce in the United States is employed on work systems using schedules other than a fixed day shift of 8 (or less) hours duration. Similar world-wide estimates have been made for industrialized countries by the International Labor Office. Work schedules grouped within these systems include permanent night shift work, rotating shift work, and regular work on shifts of greater than 8 hours duration. A number of factors encourage the use of these systems: many new industrial processes require continuous staffing; the number of industrialized countries is increasing; capital equipment costs can often be reduced by increasing or changing the hours of operation; many workers are interested in a workweek of less than five days; and, there has been a general increase in the demand for around-the-clock services.
