In this context, the “New Generation Prefecture Plan” (NGP) has focused on making better use of digital technologies to redeploy a portion of the workforce to understaffed missions and advancing them in skills. As a result, reception at the counter and processing of files were replaced by digital procedures for the application and issuance of four main titles that had so far involved approximately 4,000 agents. The restructuring objectives of the prefectural services were generally achieved despite insufficient preparation and difficult implementation of the IT projects. The lessons of this experience should make it possible to make better use of the potential opened up by dematerialisation and to put at the centre of future reforms the quality of service provided to users.
