La Transfo is an experimental and inter-public services program initiated in 2011. It seeks to create, with its partner public departments, a prototype of their specific innovation function or a “lab”. To this end, a multi-disciplinary team of residents takes up shop within the department for 7 to 10 weeks to play the role of temporary laboratory. Over a period of 1 to 2 years, the residents work with the public agents, elected officials, citizens and the entire administrative “ecosystem” on a specific topic to test, in a real situation, the future innovation function, its methods and team, its inclusion in the organization chart, etc. Beyond this operational objective, La Transfo is also designed as an open source device allowing for sharing know-how and skills among different public authorities. Inter-communication is primarily by Intertransfos, – days reserved for thinking about, exchanging and evaluating methods and actions and which bring together the teams engaged in the program and the authorities involved in these procedures.
