She specializes in the acquisition of advanced instrumentation, research and development services, and specialized manufacturing solutions, often supporting high-precision technical systems. Her work is central to delivering mission-enabling technologies through competitive, transparent, and compliant contracting processes that align with agency objectives and statutory requirements. While specific contractor names are not available, Shelley’s procurement patterns reflect a balanced engagement with both large-capacity prime contractors and small business vendors, fostering a competitive marketplace. She consistently leverages full and open competition, with a strong preference for non-set-aside awards, yet maintains active partnerships with qualified small businesses through targeted set-asides. Her contracting approach emphasizes performance-based outcomes, clear statement of work development, and rigorous source selection under FAR Part 15 procedures.
