The Department of Defense Office of Inspector General (DoD OIG) is an independent and objective office that provides oversight of DoD programs and operations. The DoD OIG also informs the Secretary of Defense, Congress, and the American Taxpayer about problems, deficiencies, and corrective actions within DoD programs and operations. The DoD OIG also serves as the Lead Inspector General for specified Overseas Contingency Operations, coordinating oversight activities and reporting quarterly to Congress on each operation. This plan builds upon the solid foundation of the previous Strategic Plan Fiscal Years 2018-2022, and was refined through a meticulous, collaborative process that spanned the entire organization.
