Increasing efficiency by means of human-centred system design

During the 1980s, developments have been taking place in several European countries to establish concepts of human-centred system design. Today the design of a technical system is often understood as the design of a more or less automated system and will always be the design of a man-machine system. The dual design approach is a set of principles to insure appropriate development of both technical and human aspects of man-machine systems. Usually project engineers tend to head for fully automated concepts. The authors discuss this approach as well as the working-process based design approach
