The Department of Veterans Affairs Enterprise Architecture (VA EA) is an efficient and integrated set of systems, tools, and resources for leaders, staff, and other stakeholders to better understand VA strategy, investment, lines of business, and information technology (IT) capabilities. As depicted in the figure below, the VA EA brings together authoritative data and information, organized by domains, helping to increase interoperability of Veteran and enabling support services, improve service delivery, and make better use of VA resources.
The VA EA is managed by the Architecture and Engineering Service (AES) Team under the Office of Information Technology (OIT).
