The approach proposed here is a digital-oriented variation of the strategic territorial approaches: diagnosis, stakeholder mapping, defining of goals, methods of action and monitoring-evaluation. There are a few warnings and key questions to be asked before launching the introduction of digital services to optimise the chances of success.

The method can apply just as well to a single project for a sector to be digitalized (Part B) as to the internal digitalization strategy specific to the local authority (Part C).

The basic principles of the method are:

• familiarisation with the potential, the tools and the culture of the digital;
• identify the prerequisites and draw up a quick diagnosis of the penetration rate of the digital on the territory;
• engage a collaborative approach to pool skills, data and resources;
• define goals in accordance with the needs, demands and practices of the users;
• consider that simple solutions can be decisive and implement pilot actions then scale up in the event of success;
• favour a gradual process of improvement and testing, rather than the immediate implementation of heavy solutions that may not be very well-adapted.
