E-Government's Role in Shifting the Paradigm of Performance in the Public Sector

The emergence of e-government changed the world of the Public Administration (PA) and the discipline of Public Management dramatically. Through the presentation of a case- study of the municipality of Palermo, this article attempts to discuss the renewed need for assessing performance of e-government services in a local government and to disclose the main critical issues in accomplishing this evaluation. Palermo is experiencing the implementation of a second- generation e-government project that is embodied in the realization of a web portal. The conceptualization of a framework to assess the performance of the digital services appears to be crucial in order to improve the system and to avoid the errors of the frst project. This work relies on a survey to the citizens and semi-structured interviews to managers in charge of the development of the project. System Dynamics, a particular kind of dynamic simulation, is used to provide the necessary feedback structure for identifying the determinants of the success of the portal.
