Résumé
Role-Playing Games (RPG) & computerized models are old & new Information & Communication Technique (ICT) tools aiming at providing support for analysis & support for negotiation processes. As learning tools RPG aim at providing either players or game organizers with better knowledge of a given situation. They thus constitute social learning support tools. Computerized models in negotiation processes aim at simulating either the negotiation itself so as to better handle the process, or the evolution of stakes to broaden the discussion. Each of these tools has already been used on its own, but each has its limits. When used jointly, at least one of them constitutes a 'like society' about which scientists &/or stakeholders can think over. This paper focuses on the interactions between both kinds of tools when dealing with negotiation issues, & is based on experiments presented in the thematic session about 'role-playing games, models & negotiation' held at the Ecological Economics conference in Sousse, Tunisia, in Mar 2002. They are analyzed & compared with a post normal posture on negotiation processes. The post normal version of a model as a scientific tool involves opening an axis [conceptual model, controlled experiment] to include a third pole: observed reality. This is a means of dealing with the complexity & uncertainty of the systems at stake, by involving the various viewpoints concerning the system. RPG are a good tool for introducing this third pole, while computerized models considerably ease their use & design. Thus, each joint use experiment is presented as a path within this triplet. Two main categories of joint use have been identified: mutual support in use & mutual support in design & analysis. In the first category, both tools are used simultaneously with different underlying conceptual models. In the second category, both tools are used one after the other & have the same underlying conceptual model. Practically speaking, the joint use of RPG & computerized models can be considered as a craft. The artisan nature of tools as well as of their methodology of use is coherent with the artisan nature of consensus building processes. Not all joint use experiments allow standardized tools & methodology to be built. However, some guidelines can be formulated for the building of suitable mediating objects for a post normal approach to negotiation process. 1 Table, 2 Figures, 65 References.
