7.1.3.1 1 Enterprise Architecture Study

Enterprise Architecture Study / Kansas DOT

KDOT’s architecture was based on a value chain model that represents the agency’s business components and relationships. It included a set of “context diagrams” showing information flow across systems and actors for major subject areas including highway asset systems, long range planning, pre-construction, construction and maintenance. While an architecture does require significant effort to create and maintain, it provides a more global and stable view of business processes and information needs than what would be produced through a piecemeal, incremental approach to system upgrades and replacements. This view can be used to plan the path from the existing set of systems to a more efficient and integrated set.
