Marianne M. Call

Marianne M. Call serves as a procurement professional responsible for managing information technology acquisitions aligned with federal contracting standards. Her role centers on executing competitive solicitations under the Federal Acquisition Regulation, with a focus on software development, systems integration, and IT services. She plays a critical part in ensuring the agency’s technology infrastructure meets operational needs through compliant, transparent, and efficient contracting processes. Her portfolio primarily encompasses complex IT service contracts requiring technical evaluation and performance-based acquisition strategies. Her contractor relationships are broadly distributed across the IT services sector, with no single vendor dominating her award history. She engages with a diverse pool of vendors, including large systems integrators, niche software developers, and small business providers, fostering a competitive marketplace. Her procurement approach emphasizes open competition, with a preference for performance-based outcomes and clear statement of work requirements that encourage innovation and accountability. Marianne demonstrates a strong commitment to socioeconomic contracting, with approximately 90.9% of her awards issued under full and open competition without set-asides, while 9.1% are structured as Total Small Business Set-Asides under FAR 19.5. This pattern reflects a balanced strategy: prioritizing broad market access while ensuring meaningful opportunities for qualified small businesses when appropriate. Her approach aligns with federal goals to promote competition and inclusion without artificially restricting the pool unless justified by mission need or market conditions. Her primary procurement focus lies in NAICS 511210 (Software Publishers), accounting for over half of her activity, followed by 541519 (Other Computer Related Services) and 541513 (Computer Facilities Management Services). She routinely procures custom software solutions, cloud-enabled applications, and managed IT infrastructure services. Her technical expertise spans enterprise software deployment, application lifecycle management, and IT operations support, positioning her as a key liaison between mission requirements and the evolving commercial technology landscape.
