Defense Reform: DOD Has Made Progress, but Needs to Further Refine and Formalize Its Reform Efforts, Report to Congressional Committees [open pdf - 2MB]
From the Highlights: "DOD spends billions of dollars each year to maintain key business operations. Section 921 of the NDAA [John S. McCain National Defense Authorization Act] for FY 2019 established requirements for DOD to reform these operations and report on their efforts. DOD has also undertaken additional efforts to reform its operations in recent years. Section 921 called for GAO [Government Accountability Office] to assess the accuracy of DOD's reported cost baselines and savings, and section 1753 of the NDAA for FY 2020 called for GAO to report on the OCMO's [Office of the Chief Management Officer] efficiency initiatives. This report assesses the extent to which DOD has (1) established valid and reliable baseline cost estimates for its business operations; (2) established well-documented cost savings estimates reflecting its reforms; and (3) coordinated its reform efforts."
