One of the central challenges of E-Government is organizational and institutional change. Professor Jane E. Fountain, the founder and Director of the National Center for Digital Government at the Kennedy School of Government, Harvard University, and her research team are currently continuing a practical research program on the development of crossagency collaboration and integration using information technologies. The project is designed to describe and explain critical success factors in successful E-Government cross-agency collaborative projects. The study should contribute significant management, economic and policy benefits as a result of better understanding how to structure conditions for success in cross-agency initiatives that rely on the Internet and related technologies.
