SOME MORE EVIDENCE FOR JUSTIFYING HUMAN-CENTRED SYSTEMS

This paper makes a contribution towards justifying the development of human-centred systems by reviving the debate about how to persuade stakeholders and other decisionmakers to vote in favor of these systems development approaches. It starts by a general discussion on how cost-effective the development of human-centred systems can be. Then the relevant part of the comprehensive human-centred systems design framework by William B. Rouse is given as an example of methodology where the issues of justification are systematically covered. Finally, some results from case studies made in Europe are quoted, with the intention to contribute some more evidence supporting the fact that human-centred systems design is superior not only from the purely functional viewpoint, but also can be justified in factual bottom-line (i.e. economic) terms.
