Tammy Smith

Tammy Smith serves as a secondary contracting professional within the Defense Information Systems Agency (DISA), supporting the acquisition of mission-critical information systems that sustain the Department of Defense’s C4I infrastructure. While not the lead contracting officer, she plays a vital role in executing complex IT procurements aligned with DISA’s strategic priorities in cybersecurity, cloud modernization, and interoperable communications. Her work typically involves supporting the full lifecycle of service-based contracts, including requirements definition, source selection support, and contract administration for technical IT services essential to national defense operations. Smith maintains a consistent working relationship with EXPRESSION NETWORKS LLC, a key contractor delivering specialized computer systems design and data infrastructure services. Her procurement patterns reflect a preference for established, high-capacity vendors with proven expertise in secure IT environments, though she actively supports a diverse supplier base through structured small business participation. Vendor partnerships are typically performance-based, emphasizing deliverables tied to cybersecurity compliance, system integration, and cloud-enabled mission support. Her contracting portfolio demonstrates a strong orientation toward open competition, with 82.8% of awards issued without set-aside restrictions. Nevertheless, she consistently facilitates opportunities for small businesses, particularly through Total Small Business Set-Asides (10.3%) and Service-Disabled Veteran-Owned Small Business (SDVOSB) set-asides (6.9%), reflecting DISA’s broader commitment to socioeconomic contracting goals under FAR Part 19. Smith’s primary procurement focus lies in NAICS 541512 (Computer Systems Design Services) and 541519 (Other Computer Related Services), reflecting deep expertise in securing custom software development, systems integration, and enterprise IT support. She also regularly procures computing infrastructure services under NAICS 518210 and facilities management under 541513, underscoring her technical proficiency in cloud-enabled environments, data center operations, and mission-critical IT sustainment for DoD networks.
