The President of the Region Champagne-Ardenne, Mr Martin said: “Before, we were thinking in a compartmentalized way… on the question of the youth policy, for example, we did not have a clear vision on all the actors, on the available funds, the current plans… even from our own administration and in our own region… We were losing money, time, and efficiency. We changed everything since the launching of the multi-level governance charter. In fact, we used it to develop a 3D digital tool which allows to visualize data, stakeholders, competences of the different districts, public and private actors concerned at the various levels, in order of importance.

We decided to install an other simulator in the middle of the meeting room of the regional representatives, an other one in front of the Region hall, et each citizen can use it freely…”
