La représentation des processus comme support de la décision collective

In a professional association, the problem of making a generic business processes census displays a fundamental group decision problem: How to obtain a consensus with several experts working in different contexts and with different practices? The GAMETH approach based on process representation, allowed us to find five functions and to represent the corresponding processes. The process mapping is adaptable to any society of the association. The processes can be different from one society member of the association to another and are depending of the organization. In this document, we highlight the constructivist approach benefit of a process representation. This approach leads us to a good commensurability of experts' interpretative framework, commensurability which is necessary for a consensus in a group decision process.
