: The process of aggregating individual judgments in a population at large and in a synergistic group (team) is fundamentally different. Arrow's Impossibility Theorem shows that it is generally impossible to derive a rational group choice from individual ordinal preferences with more than two alternatives. This general impossibility has led to the development of a distinct branch of knowledge for each group type, quantitative for the former and qualitative for the latter. By using ratio scales, AIM has removed the impossibility conclusively and be the theory that makes group decision making a continuum between pure voting on one end and consensus building on the other end. This paper discusses a technically feasible voting process with AMP, ranging from eliciting voters' intensity judgment of preference to a full multicriteria voting. As for a synergistic group; the AMP offers tools to address major problems and issues in teamwork, as well as to promote organizational learning. The AMP enables a facilitator of a synergistic group decision making to use consensus building and voting in different parts of the problem on hand to come to a group decision.
