2022 Annual Report: Additional Opportunities to Reduce Fragmentation, Overlap, and Duplication and Achieve Billions of Dollars in Financial Benefits, Report to Congressional Addressees [open pdf - 6MB]
From the Highlights: "GAO [Government Accountability Office] issues annual reports on federal programs, agencies, offices, and initiatives--either within departments or government-wide--that have duplicative goals or activities. As part of this work, GAO also identifies additional opportunities for greater efficiency and effectiveness that result in cost savings or enhanced revenue collection. This report discusses new opportunities for achieving billions of dollars in financial savings and improving the efficiency and effectiveness of a wide range of federal programs. It also evaluates progress in addressing actions identified in GAO's previous 11 annual reports. In addition, the report provides examples of open actions where further steps by Congress and executive branch agencies could yield significant financial and non-financial benefits."
