The workshop is linking good practice in Germany with the aspect of economic efficiency. On the one side, the Federal Ministry of the Interior will present the elements for sustainable eGovernment that have been developed in Germany. In a second step, the aspect of economic efficiency, a very topical subject for eGovernment projects in all EU Member States, will be at the centre of interest. Differing aspects of economic efficiency in eGovernment will be discussed at the national, regional and local levels.
