Abstract: This paper presents theoretical arguments for the importance of participative decision- making, lists several problems related to group decision-making and presents and discusses how the Analytical Hierarchy Process (AHP) can address these problems. Particular attention is focussed on how the individual participants’ preferences can be accommodated in a group decision stressing that the normal emphasis on consensus may not always be the way to go. Investigating the geometric mean as an alternative in real-world decision situations is suggested. The application of AHP to decision- making in the synergistic group is accepted and the possibility of expanding the use of AHP into areas where substantial agreement, compatible values and objectives are unlikely is suggested.
