This phase involves integrates the individual evaluations, carried out by each stakeholder, who has already individually expressed their criteria and weights based on temporal value. These evaluation are then combined into a single evaluation framework. The final matrix represents the synthesis of the evaluations developed thus far. Each element indicates the feasibility of a given alternative for a specific stakeholder based on their expressed preferences, strategic issues, and priorities. The chapter will be organised as follows. First, the MACTOR method and its case-based reworking will presents the analytical method developed by Godet. This method is based on an alliances and conflicts matrix and will be adapted and used to study the reciprocal influences among stakeholders, their strategies, their convergences and divergences in objectives, and the existing balance of power.
