A method for scoring changes of components of a concept by a group of evaluators in a collective decision process is presented. First, the level of disagreement with the components is collected together with comments indicating desired changes. The expected incremental decrease of the overall disagreement level achievable by a component change is computed for a given probability that a formulation can be found that is acceptable by both agreeing and disagreeing evaluators. Performing this computation for different values of the compromise probability yields a score indicating the expected incremental decrease in overall disagreement achievable by a component change. Additionally, the minimum compromise probability where an improvement is possible and the expected relative improvements are provided. Next, alternative formulations for the selected components are drafted and subjected to a second round of voting. For each component the alternative yielding the maximum incremental improvement of overall consent is selected, where the sequence in which the components are scrutinized is determined by the score computed in the first step. In this way, an optimal new version of the concept is produced.
