| Tiivistelmä: | This paper develops and presents a comprehensive cost-benefit framework for evaluating design decisions for a variety of scenarios. It provides guidance regarding the number of available information dimensions to incorporate in a computer-based decision aid. Simulation experiments are conducted with a model based on the cost-benefit framework to evaluate how many information dimensions to include for a specific information matrix size to achieve a balance between information use costs and decision quality. Based upon extensive simulation analyses for a hypothetical decision maker the practical guideline found for designers is to include only the top half of the relevant information dimensions in any specific decision support system. Over a large number of repeating choice decisions the savings in cognitive effort and information gathering costs offset relatively minor losses in decision quality. |
