The report's motivation recalls for us the original rationale for "The New Way Forward", aka "the surge":

Since 2001, Congress has appropriated about $640 billion for the global war on terrorism, the majority of this for operations in Iraq. In January 2007, the President announced The New Way Forward to stem violence in Iraq and enable the Iraqi government to foster national reconciliation. This new strategy established goals and objectives to achieve over 12 to 18 months, or by July 2008.

GAO discusses progress in meeting key goals in The New Way Forward: (1) improve security conditions; (2) develop capable Iraqi security forces; and help the Iraqi government (3) enact key legislation, (4) spend capital budgets, and (5) provide essential services. GAO also discusses U.S. strategies for Iraq. (emphasis added -- MDC)

Summing up, GAO concludes:

The New Way Forward responded to failures in prior strategies that prematurely transferred security responsibilities to Iraqi forces or belatedly responded to growing sectarian violence. Overall violence, as measured by enemy-initiated attacks, fell about 70 percent in Iraq, from about 180 attacks per day in June 2007 to about 50 attacks per day in February 2008. Security gains have largely resulted from (1) the increase in U.S. combat forces, (2) the creation of nongovernmental security forces such as Sons of Iraq, and (3) the Mahdi Army’s declaration of a cease fire. Average daily attacks were at higher levels in March and April before declining in May 2008. The security environment remains volatile and dangerous. The number of trained Iraqi forces has increased from 323,000 in January 2007 to 478,000 in May 2008; many units are leading counterinsurgency operations. However, the Department of Defense reported in March 2008 that the number of Iraqi units capable of performing operations without U.S. assistance has remained at about 10 percent. Several factors have complicated the development of capable security forces, including the lack of a single unified force, sectarian and militia influences, and continued dependence on U.S. and coalition forces.

The Iraqi government has enacted key legislation to return some Ba'athists to government, give amnesty to detained Iraqis, and define provincial powers. However, it has not yet enacted other important legislation for sharing oil resources or holding provincial elections. Efforts to complete the constitutional review have also stalled.
