The KerDST gallery presents the diversity of Evaluation Exercises carried out (or underway at any moment in time) with the aid of the KerBabel Deliberation Matrix. The KerDST is a tool that permits an individual or group of users to create the structure for a participatory multi-stakeholder multi-criteria Evaluation Exercise. Users work on-line to build up a didactic presentation of the judgements offered by each category of stakeholders, for each of the objects under evaluation, with reference to a spectrum of governance or quality-performance issues.
