Governments are employing modern information and communication technologies to serve society better. Raising the effectiveness and quality of government services is not only a matter of new technologies; it also involves clear vision and objectives as well as a sound business strategy. Information systems need to support internal work within a government's boundaries, serve customers through digital interfaces and leverage digital relationships among social partners. To implement such systems, preparatory work is required in both organization and technology. A new public information management philosophy underlies this significant revamping of the value propositions made to customers. The ongoing enrichment of the Greek Ministry's of Finance e-services follows an ICDT-like business logic. A key factor of all these advances is the re-orientation of information systems for customer-centric service.
