Mackay was Deputy Secretary of Veterans Affairs from May 2001 to October 2003.[10] As the department's second in command and designated chief operating officer, he had operational authority over the department's three major agencies: the Veterans Health Administration (VHA), the nation's largest integrated healthcare system; the Veterans Benefits Administration (VBA); and the National Cemetery Administration. He concentrated on departmental management initiating a Strategic Management Council, reformulating the departmental budget process, and changing the internal merit system for GS/SES personnel. He was concentrated on the CARES project, a capital asset realignment of VHA; enhanced use leasing; lowering the backlog of pending veterans' claims; achievement and maintenance of a clean audit; the National Shrine Commitment, an effort to raise, and make standard, the condition of the national cemeteries; and VetFran, a program for transitioning veterans to aid them in starting franchise businesses. He was also, with David Chu, a founding co-chair of the VA-DoD Joint Executive Council to increase interdepartmental collaboration and sharing. Upon his departure, then-Secretary Anthony Principi stated, "Dr. Mackay brought to VA the discipline of the business world and the compassion of a man who cares deeply for America's veterans. His legacy is a more-focused VA better able to meet the needs of veterans."[11]
From 1993 to 1995, Mackay served as military assistant to then-Assistant Secretary of Defense for International Security Policy, Ashton Carter.[12] During this time, the office was re-organized to focus on cooperative de-nuclearization, execution of the Nunn-Lugar threat reduction program, nuclear weapons policy, and counter-proliferation.
