GAO and Inspector General Recommendations to Agencies: An Introduction [April 12, 2021] [open pdf - 452KB]
From the Document: "Congress has established a number of institutions dedicated to monitoring and reporting on federal agencies and making recommendations to improve their integrity, efficiency, and effectiveness. These entities include dozens of statutory Offices of Inspector General (OIGs) and the Government Accountability Office (GAO), each of which has a mission focused on the economy, efficiency, and effectiveness of the federal government's operations. [...] This In Focus introduces the topic of GAO and OIG recommendations, their underlying statutory frameworks, and how they might be relevant to Congress. While this In Focus covers both GAO and OIG recommendations because of their practical similarities, GAO and the OIGs are established by different statutes, have distinct missions and roles, and perform their duties in their own ways."
