Tammie P Lett-Chalmers

Tammie P. Lett-Chalmers serves as a Contract Specialist at the Headquarters Defense Contract Management Agency (DCMA), where she plays a critical role in ensuring the integrity of defense acquisition contracts through rigorous oversight, compliance monitoring, and contract administration. Her work directly supports DCMA’s mission to safeguard taxpayer interests by verifying contractor performance and adherence to contractual obligations across the Department of Defense. She primarily manages service-based acquisitions requiring technical expertise in information technology, data services, and operational support, with a focus on ensuring contractual deliverables meet stringent quality assurance standards and federal procurement regulations. Lett-Chalmers collaborates with a diverse range of vendors, including large defense contractors and specialized service providers, to execute complex, performance-based contracts. While no single contractor dominates her portfolio, her contracting patterns reflect a preference for firms with proven capabilities in IT infrastructure, software development, and mission support services. She maintains professional, compliance-driven relationships grounded in FAR principles, emphasizing accountability, transparency, and contractor performance evaluation. Her procurement approach is overwhelmingly non-set-aside, with 96% of acquisitions conducted under full and open competition, reflecting DCMA’s emphasis on technical merit and mission readiness. Nevertheless, she actively supports small business participation, with approximately 4% of her awards allocated to Total Small Business Set-Asides under FAR 19.5, demonstrating a measured but consistent commitment to socioeconomic contracting goals without compromising acquisition efficiency. Lett-Chalmers specializes in procurements governed by NAICS codes 511210 (Software Publishers), 519130 (Internet Publishing and Broadcasting), and 519190 (Other Information Services), indicating a strong focus on digital content, data management, and cloud-enabled services. She also regularly supports acquisitions in 721110 (Hotels and Motels) for logistical and travel-related needs and 541519 (Other Computer-Related Services) for specialized IT support. Her technical domain expertise centers on information systems, cybersecurity-enabled services, and mission-critical administrative support, ensuring contracts align with DoD’s evolving operational requirements.
