The fulfillment of e-Government visions is dependent of and leads to increased vertical and horizontal integration of government operations and services. E-government leverages the IT infrastructures to create new kinds of applications and services. A poorly designed infrastructure can block interoperability and severely hinder the migration towards e-government.

E-Government information systems (EGIS) are increasingly interlinked using the physical network infrastructure. In addition, the IT infrastructure contains more and more services for supporting interoperability and communication. The demand for communication and collaboration between organizations as well as interoperability among systems is steadily increasing. Therefore, business processes and supporting IT infrastructures need to be enhanced, redesigned, streamlined, interfaced, and integrated across various governmental levels and branches presumably leading to gains in internal effectiveness and efficiency as well as to improved internal and external services.
