Resumen
Given the importance of eGovernment portals as an integral access interface of modern public service provision, this contribution concentrates on the issue of the dimensions and derived success factors of these information systems. Starting with the DeLone & McLean IS success model and the resource-based view as foundations, this article conceptualizes the important success factors of eGovernment portals and then integrates these into a research model. The empirical results show the importance of the different dimensions of eGovernment Portal Management as well as the development of eGovernment portals so far. For public service portals on the local level the key management dimensions are information, system, service and privacy management. The evaluation of these dimensions as well as perceived internal and external success in public administration institutions complement user-based quality assessments and highlight organizational strengths and weaknesses.
