The detailed roadmap for the Interoperable Digital Public Service defines the different business capabilities that will have to be developed, along with the ABB that will help to realize these digital business capabilities. eGovera Upscale is the recommended approach to generate this roadmap. However, if this approach (that asks for a considerable time investment from the FPA) is considered too detailed, the project quick assessment is an alternative support tool to provide some guidance. The last alternative is to use the eGovERA reference architecture(s) to execute a design and analysis without relying on the support tools available on the EU Interoperable Europe Portal.
