High-Risk Series: Dedicated Leadership Needed to Address Limited Progress in Most High-Risk Areas, Report to Congressional Committees [open pdf - 7MB]
From the Highlights: "The federal government is one of the world's largest and most complex entities; about $6.6 trillion in outlays in fiscal year 2020 funded a broad array of programs and operations. GAO's [Government Accountability Office] High-Risk Series identifies government operations with vulnerabilities to fraud, waste, abuse, and mismanagement, or in need of transformation to address economy, efficiency, or effectiveness challenges. This biennial update describes the status of high-risk areas, outlines actions that are still needed to assure further progress, and identifies any new high-risk areas needing attention by the executive branch and Congress. Solutions to high-risk problems save billions of dollars, improve service to the public, and strengthen government performance and accountability."
