Abstract

A graphical cost-benefit approach to computer systems selection is presented. Using a cost-benefit graph the decision maker can select among alternative computer systems while considering not only the cost/benefit ratio, but also the relative importance of the benefit and cost factors in a given situation. In order to utilize the graphical approach, cost values of the alternatives have to be transformed onto a normalized-cost scale. Various transformation methods, which are based on linear, subjective and utility theory approaches, are discussed. We recommend the use of the graphical cost-benefit approach in conjunction with a cost transformation based on the utility model; this allows incorporation of risk and uncertainty consideration into the selection process.
