The VA EA is an evolving entity that is built through an ongoing collaborative effort between the Department’s business and technology communities and the Office of Enterprise Architecture within the Office of Information and Technology (OI&T). As Department goals, priorities, business needs, and plans change, the VA EA is updated to maintain its relevance as a transformation tool and authoritative information resource. The latest VA EA changes and updates are summarized in "What's New."

The Office of Enterprise Architecture welcomes your thoughts and ideas. Your input is an invaluable contribution to the success of the VA EA and the VA’s mission and goals. Sharing information across the enterprise and leveraging the collaborative feedback from within the Department provides a collective, federated effort to better serve Veterans and beneficiaries. Please contact us regarding how we can improve the VA EA to better serve our Veterans and beneficiaries, as well as those who support them.
