VA EA Content
The Veterans Affairs Enterprise Architecture organizes data and information by domains called strategic, business, data and information, systems and applications, network and infrastructure, and security information. These domains reflect the areas of business relevant to VA leaders and staff that might use these data. Hover over the graphic below to learn more.
VA is a large and complex organization. Although understanding the content of each EA Domain is important, the real benefit of using enterprise architecture is to gain insight into the complex relationships between the domains and information in them. For example if one can understand what combination of operational processes, activities, and measurable outputs are driving strategic outcomes, one can use that information to evaluate which strategies and implementation plans are effective, and which are not.
The relationships between the domains’ major elements (i.e., the products and tools the Domain contains) are shown in the VA EA Conceptual Metamodel below. This shows connection points between various elements in the VA EA. The ability to trace high level outcomes to operational activities, frequently referred to as “line-of-sight” traceability, informs both operational and strategic decisions.
