The intellectual roots of HCI are work science, work psychology, and ergonomics. All those disciplines were basically triggered by a more or less economically-driven demand for an improved workplace (Karwowski,W., 2006). One strategy was to select and train people to increase work performance, the other to adapt workplace design, machines and so forth to the skills and capabilities of workers. In this context, efficiency and effectiveness was clearly an institutional and not a personal goal. Better performance equaled more money. The human was viewed as a necessary, but yet improvable part of the system.
