The issue of presenting alternatives to the decision maker in multiple criteria decision support is addressed. The traditional approach, advocated in many multiple criteria techniques, suggests that alternatives should be presented to the decision maker as a vector of criteria scores. We consider the merits of an augmented approach which, in addition to presenting the criteria scores to the decision maker, also makes the values of the underlying decision variables directly available to the decision maker. We describe an experiment where decision makers compare the traditional approach with this augmented approach. In this experiment, a group of decision makers solve a multiple criteria decision making problem which is constructed to uniquely reflect each decision maker's perceptions concerning the decision scenario. We are able to demonstrate that the augmented approach results in 1) the selection of markedly different alternatives than those selected using the traditional approach, 2) an increase in user satisfaction with tile information system product, 3) a higher level of satisfaction with the alternative selected.
