The Department of Defense, through the Washington Headquarters Services, is issuing a Request for Information (RFI) for the development of the End-to-End Framework for Enhanced Innovative Capability Development (DEFEND) Software System. This initiative aims to explore and assess contractor capabilities in models, simulations, and software processes that can support the DoD's materiel capability development, ultimately transitioning these capabilities into a government-owned system. The RFI emphasizes the importance of integrating analytic and functional requirements to enhance the capability development process within the DoD. Interested firms, particularly small businesses, must submit their responses by October 4, 2024, ensuring compliance with security requirements, including a TOP SECRET facility clearance. For further inquiries, firms can contact Warren (Trey) Arthur at warren.g.arthur.civ@mail.mil or Maria Evans at maria.t.evans.civ@mail.mil.
