Ann O'Rourke

Ann O’Rourke serves as a key procurement professional within the IT Contracting Division - PL83 of the Defense Information Systems Agency, where she manages mission-critical acquisitions to sustain and modernize defense-wide information systems. Her responsibilities encompass the full lifecycle of IT service contracts, with a focus on engineering services that enhance cybersecurity resilience, interoperability, and legacy system modernization. She plays a central role in executing strategic IT initiatives aligned with DoD objectives, ensuring that technical solutions meet stringent security and operational requirements for command, control, and communications infrastructure. Her acquisitions are predominantly engineering-driven, targeting complex software development, systems integration, and mission-critical platform sustainment. O’Rourke maintains a broad network of qualified contractors specializing in defense-grade IT engineering, including large systems integrators and niche technical firms with deep expertise in DoD environments. While no single contractor dominates her portfolio, she consistently engages vendors with proven capabilities in secure software development, network architecture, and cyber-physical system integration. Her contracting patterns reflect a preference for performance-based, outcome-oriented solicitations that emphasize technical excellence, compliance with DoD STIGs and NIST frameworks, and proven track records in classified and unclassified mission support. Her procurement strategy shows no reliance on socioeconomic set-asides, with 100% of awards issued under full and open competition. This reflects a mission-driven prioritization of technical capability and readiness over socioeconomic criteria, consistent with the high-stakes nature of defense IT operations. While small business participation is not formally incentivized, qualified small firms with demonstrated expertise in defense engineering are regularly evaluated and selected based on technical merit. Her primary focus is on NAICS 541330 (Engineering Services), encompassing custom software development, systems engineering, cybersecurity architecture, and infrastructure modernization. She procures services that support secure cloud migration, zero-trust architecture implementation, and legacy system obsolescence mitigation—domains requiring deep technical proficiency and adherence to DoD acquisition regulations.
