A System Dynamics model to identify and measure the paper digitization advantages in Public Administration Nunzio Casalino 1 , Stefano Armenia 2 , Mauro Draoli 3 Abstract. This study provides a System Dynamics model built to identify the benefits arising from the process of digitization in the Italian Public Administration. The paper describes the process in terms of the causal relationships between systemic variables that define the underlying structure of the problem. The analysis focuses on the interaction between the “outer world” of the citizens and the “inner world” of the Italian Administrations, by designing a causal loop diagram and a stock and flow simulation model. The systemic approach allows considering many crucial aspects for the digitization problem and provides a rich analysis that shows how those obstacles brought forward by social and psychological factors may become a great obstacle to organizational change. Introduction The process of managing digital documents is recognized as faster, safer and cheaper than the paper one. Granting fast process and reducing costs both for the public and for the private sectors, it can be used as a high leverage tool in order to gain a higher efficiency rate [1], [5]. The e-government is a broad process of innovation in public administration with particular reference to the internal administrative process and to the relations with the outside world. There is a positive correlation between the gradual diffusion of technology within the Public Administration and increasing socio-economic well-being [14]. Paper dematerialization is an issue that has affected mostly the existing rules making a radical transformation, still in place, of the activities of public and private institutions. In particular, the collection of norms known as “Codice dell’Amministrazione Digitale” is on a real overhaul that transforms the existing digitization in a strong requirement for the institutions, introducing at the same time, in relation to the documentation to be submitted to the administration, new guaranteed rights to citizens and companies [10], [11]. The following government plan, known as “Piano E-gov 2012” is another key initiative for the future of the Italian country. In a context of economic crisis this Plan, in line 1 Università degli Studi “Guglielmo Marconi”, Dipartimento di Scienze Economiche ed Aziendali, Roma, Italy, n.casalino@unimarconi.it 2 CATTID, Università degli Studi di Roma “La Sapienza”, Roma, Italy, armenia@cattid.uniroma1.it 3 CNIPA - Centro Nazionale per l’Informatica nella PA, Roma, Italy, draoli@cnipa.it
