From introduction: Governments are extraordinary information creators, users, and disseminators. I-government focuses attention on the flow and structuring of information within government (Mayer-Schoenberger and Lazer, this volume). Government actors engage in knowledge work, specifically, in the creation, sharing, and communication of information. They design and redesign processes by which information flows according to legislative mandate, organizational practice and public need. Recently, they have sought to rethink information flows in order to leverage benefits from information and communication technologies. When public sector actors seek to change these information flows at any appreciable level of complexity, they inevitably engage in complex organizational and interorganizational change.
