Diane R Clarke

Diane R. Clarke serves as a Contract Specialist within Washington Headquarters Services (WHS), supporting the Department of Defense’s mission to deliver enterprise-wide administrative and operational services. In this role, she manages the full lifecycle of complex acquisitions, from requirements validation and market research through solicitation, evaluation, award, and contract administration. Her portfolio centers on professional services and technology-enabled solutions that enhance DoD institutional efficiency, with a focus on consulting, systems design, and digital transformation initiatives. Clarke ensures compliance with FAR and DFARS regulations while aligning procurements with WHS’s strategic priorities of modernizing defense infrastructure and optimizing resource management. Clarke maintains consistent working relationships with a core group of contractors, including Clarity Innovations LLC, Cynergy Professional Systems LLC, Signature Renovations LLC, AMD International Technologies LLC, and Guidehouse Inc. These partnerships reflect a preference for established firms with proven expertise in management consulting, IT systems design, and facility modernization services. Her contracting approach emphasizes performance-based outcomes, clear statement of work development, and rigorous source selection processes, fostering long-term vendor collaboration grounded in accountability and mission alignment. Her procurement strategy prioritizes open competition, with approximately 90% of acquisitions issued without set-asides, reflecting the high-complexity and specialized nature of the services required. However, she actively supports small business participation through Total Small Business Set-Asides under FAR 19.5, consistently reserving a portion of eligible requirements for small businesses to ensure broad market engagement and competitive diversity. Clarke’s primary NAICS focus areas include 511210 (Software Publishers), 541611 (Administrative Management Consulting), 541512 (Computer Systems Design Services), and 561920 (Convention and Trade Show Organizers), underscoring her specialization in enterprise software, management consulting, and event support services. She frequently procures custom software solutions, IT infrastructure modernization, and administrative support systems that directly enable DoD-wide operational readiness and digital transformation efforts.
