The Italian Public Administrations during the last years were involved in a long term-process of reform to “reinvent” the public sector in accordance with the New Public Management (NPM) principles. The last change was realized with the law 150/2009 that introduced the “performance” cycle in the Italian public sector. The Italian Army is involved in this changing process, as well as the other public organizations, by implementing a performance management system (PMS). ICT, another “megatrend” of NPM, which plays an invaluable role in this process, is the “stone guest” of a performance management system. In fact an “unresponsive” information system can be the Achilles’s heel of PMS. This article aims to respond to the following question: How could ICT contribute to the implementation of effective PMS in the Italian Army? The article is a work in progress.
