The New York State-Local Internet Gateway Prototype was built to identify, demonstrate, and evaluate key factors associated with the design, development, and deployment of a single point of contact for G2G work among state and local governments. The Prototype development was conducted in three stages. The first focused on the refinement of the idea of a gateway and the selection of applications to be included in the Prototype. The second stage was the development of a Prototype (the Gateway and three business applications), and the final stage consisted of Prototype testing and refinement. During these three stages, the project participants were organized into specialized teams and partnered with corporate software development teams. Together, they then tested the Prototype.
