Introduction: The Substitution of Human Faculties with Technology: Powered Machines The development of the steam engine in 1776 represented a major advance in the construction of powered machines and marked the beginning of the Industrial Revolution. Powered engines and machines soon became common and led to the first extensive mechanization of manufacturing processes. The development of large-scale machine production on one hand decreased the demand for craftsmen and increased the demand for semiskilled and unskilled workers and on the other altered the nature of the work process from one mainly depending on physical power to one primarily dominated by technology.

Assembly line An assembly line is an industrial arrangement of machines, equipment, and workers for continuous flow of workpieces in mass production operations. An assembly line is designed by determining the sequences of operations for manufacture of each product component as well as the final product. Each movement of material is made as simple and short as possible with no cross flow or backtracking. Work assignments, numbers of machines, and production rates are programmed so that all operations performed along the line are compatible.
