Special focus is the evaluation of pilot projects using the platform:• The European youth organization AEGEE will improve its communication and discussion process with its members• In France, two institutions, the City of Paris and the French federation of community centers will foster youth empowerment and inclusion• In Italy and Slovenia a cross-border pilot will aim at guiding young community managers that will interact with their respective city administrationA sustainable impact is created through an innovation strategy which among other measures includes the deployment of the platform.
