The long-term sustainability is linked to many other topics, such as the desirability, feasibility and profitability (either financial or in terms of time) from all stakeholders involved. Service providers are concerned with adopting eIDAS with very small budget and there are assumptions about CEF eID infrastructure and questions if it is ready or good enough for private service provision. It is therefore also important to assess the question of desirability, both from the eID service users (citizens and businesses) and from service provider perspective. We should always have in mind that LEPS results have to be put in the context of profitability, feasibility or desirability of use of CEF e-ID services by private service providers. Without possibility that private SP connect to eIDAS node, or without proper support by eIDAS network stakeholders, LEPS results will have no uptake.
The overall methodology for the feasibility and sustainability of a project aiming to connect private SP to eIDAS nodes in order to use CEF eID services, can be defined in five steps:
- Technical question: “Is the project technically possible with this resource and within this time limits?”
- Economic: “Will it increase cost/benefits?”
- Legal: “Is the project legally viable?”
- Organizational/Operational: “Will the users accept the change?” and “How effective the project will be in solving the problem at hand?”
