A process to support and to report collaborative decision

This paper introduces a process to support a collaborative decision made by experts, like collaborative modelling, design choice or collaborative validation, and a formal framework to understand and analyze the final decision. We propose a methodology in two steps: a graphical modeling of the debate to support experts and a more formal framework to record the rationale of the decision. The intended benefits of this methodology are to support the collaborative decision process and to record the motivations of the decision, we illustrate it with an industrial study case.
