The DISA Business Systems PMO is seeking information from potential sources for the modernization, rationalization, and full lifecycle sustainment of its financial systems. The work includes the complete operation, maintenance, and security of these systems, along with designing, testing, and migrating them. It also involves supporting ongoing operations, implementing upgrades on government-provided infrastructure, and transitioning systems to cloud environments. Additional tasks include developing engineering architectures, managing configuration, and ensuring compliance with the NIST Risk Management Framework. No specific budget, performance location, or non-bid timelines are detailed in this description.
