This chapter describes the DoD (Department of Defense) policy goal toward Net centric transformation as an example of enterprise architecture in practice. An integrated architecture across the enterprise provided by the DoD Global Information Grid (GIG) is a key ingredient toward meeting Net centricity. The chapter provides background information on key concepts and details the steps necessary to meeting the Net-ready key performance parameter (NR-KPP). The DoD architecture framework provides the Supporting System View, Operational View, and Technical Standards View architecture products that each DoD program must create to meet the Net-centric model. The Net-centric transformation is detailed based on the Net-centric data strategy, Net-centric IA strategy, use of service-oriented architecture, and use of a communications transport strategy. The path toward Net centricity is a significant and long-term effort and the chapter focuses on specific areas that affect DoD programs on their path toward Net-centric compliance. The implementation of enterprise services and the use of key technical standards are also discussed as emerging efforts.
