In order to derive optimum design specifications based on total evaluation performed on a product as a whole instead of individual design items during a process of determining design specifications involving a plurality of design items, candidates for the product specifications are selected by controlling design parameters for each of the design items in an integrated manner, computing values of a plurality of evaluation items evaluating candidates for the design specifications and performing total evaluation on all the evaluation items based on their computed values through collaboration among a plurality of design sections altogether auto-correcting all relevant design parameters quickly and relaxing as well as reassessing design constraints for a design parameter.
