Welcome to enterprise architecture (EA). EA is a strategic asset used to manage and align the commonwealth's business processes and information technology (IT) infrastructure/solutions with the state's overall strategy. EA is also a comprehensive framework and repository, which defines:

  • Models that specify the current (as is) and target (to be) architecture environments
  • Information necessary to perform the commonwealth's mission
  • Technologies necessary to perform that mission
  • Processes necessary for implementing new technologies in response to the commonwealth's changing business needs

EA is part of an overall comprehensive Commonwealth of Virginia (COV) IT resource management (ITRM) program as shown in Figure 1 below.
