SIGIR was an independent government agency created by the Congress to provide oversight of the use (or misuse) of the $52 billion U.S. reconstruction program in Iraq.
SIGIR's mission was to provide independent and objective oversight of U.S.-funded Iraq reconstruction policies, programs, and operations through comprehensive audits, inspections, and investigations.
These changes to the law and to key agencies’ policies and procedures have increased management efficiencies and influenced the development of more effective approaches to overseas contingency operations.
Some examples of how SIGIR's oversight work has affected U.S. policy include: (1) the reorganization of the Department of State's anti-corruption programs in Iraq; (2) the imposition by Congress of stricter limitations on the amount of Commander's Emergency Response Program funds that can be used on any one project; (3) the establishment of improved processes for transferring U.S.-funded assets to the government of Iraq; (4) the issuance by the Office of Management and Budget of updated procurement guidance, including a number of management and operational best practices that should be considered in planning contingency operations and responding to national emergencies; and (5) the establishment by the Congress of two new special inspectors general modeled on SIGIR – SIGAR, to oversee U.S.-funded reconstruction efforts in Afghanistan, and SIGTARP, to oversee the Department of Treasury's $700 billion Troubled Asset Relief Program (TARP).
SIGIR's findings and analyses have also contributed to key policy papers produced by Congressional Committees, think tanks, and policy review bodies, such as the Gansler Commission, the Commission on Wartime Contracting in Iraq and Afghanistan, and the Iraq Study Group.
