1 Erecting the Public Sector Information Exchange By Alon Peled Department of Political Science and Public Administration The Hebrew University of Jerusalem, Israel Alon.Peled@post.harvard.edu Abstract The paper employs three case studies of three separate computer projects to illustrate how information sharing among public sector agencies can be incentivized. The United States Department of Homeland Security's Homeland Security Information System (HSIN) project demonstrates that bureaucratic politics must take primacy over technology, to ensure efficient information sharing. The paper then proposes to advance information sharing via a Public Sector Information Exchange (PSIE). The Dutch RINIS project illustrates the potential success of such an information sharing arena. The deNovis bureaucratic language computerization project demonstrates the possibilities of automating a bureaucratic language to facilitate information sharing transactions in the proposed PSIE.
