Defense Management: U.S. Southern Command Demonstrates Interagency Collaboration, but Its Haiti Disaster Response Revealed Challenges Conducting a Large Military Operation
A letter report issued by the Government Accountability Office with an abstract that begins "U.S. Southern Command (SOUTHCOM) has been cited as having mature interagency processes and coordinating mechanisms. As evidenced by the earthquakes that shook Haiti in January 2010, the challenges that SOUTHCOM faces require coordinated efforts from U.S. government agencies, international partners, and nongovernmental and private organizations. This report (1) assesses the extent that SOUTHCOM exhibits key attributes that enhance and sustain collaboration with interagency and other stakeholders and (2) evaluates SOUTHCOM's approach for developing an organizational structure that facilitates interagency collaboration and positions the command to conduct a full range of missions. To conduct this review, GAO analyzed SOUTHCOM documents, conducted interviews with the command and a number of its partners, and visited three U.S. embassies in the Caribbean and Central and South America."

Defense Logistics: DOD Needs to Take Additional Actions to Address Challenges in Supply Chain Management
A letter report issued by the Government Accountability Office with an abstract that begins "DOD estimated that overall spending on logistics, including supply chain management, was more than $210 billion in fiscal year 2010. Because of long-standing weaknesses in supply chain management, GAO has designated DOD supply chain management as a high-risk area and identified three focus areas for improvement--requirements forecasting, asset visibility, and materiel distribution. GAO reviewed the extent to which DOD has developed and implemented (1) corrective action plans that address challenges in the three focus areas, (2) an effective program for monitoring and validating the effectiveness and sustainability of supply chain management corrective actions, and (3) an ability to demonstrate supply chain management progress. GAO prepared this report to assist Congress in its oversight of DOD's supply chain management. GAO reviewed strategic and improvement plans, reviewed documents detailing the performance management framework, and assessed performance measures."

Coast Guard: Action Needed As Approved Deepwater Program Remains Unachievable
A letter report issued by the Government Accountability Office with an abstract that begins "The Deepwater Program includes efforts to build or modernize ships and aircraft, including supporting capabilities. In 2007, the Coast Guard took over the systems integrator role from Integrated Coast Guard Systems (ICGS) and established a $24.2 billion program baseline which included schedule and performance parameters. Last year, GAO reported that Deepwater had exceeded cost and schedule parameters, and recommended a comprehensive study to assess the mix of assets needed in a cost-constrained environment given the approved baseline was no longer feasible. GAO assessed the (1) extent to which the program is exceeding the 2007 baseline and credibility of selected cost estimates and schedules; (2) execution, design, and testing of assets; and (3) Coast Guard's efforts to conduct a fleet mix analysis. GAO reviewed key Coast Guard documents and applied criteria from GAO's cost guide."

Tax Preparer Regulation: Improving Tax Return Accuracy Depends on IRS's Use of New Requirements
Testimony issued by the Government Accountability Office with an abstract that begins "Paid preparers are a cornerstone of the U.S. tax system, as they prepare approximately 60 percent of all tax returns filed, and their actions have an enormous impact on the Internal Revenue Service's (IRS) ability to administer tax laws effectively. In previous work, GAO found that taxpayers were not always served well by their paid preparers, and GAO proposed stricter oversight of preparers. In 2010, IRS began implementing new requirements for paid preparers and believes that the requirements will increase taxpayers' compliance. This testimony addresses (1) prior GAO work on paid preparer performance, (2) IRS's progress in implementing the new requirements, and (3) how IRS can use the requirements to improve taxpayer compliance. It is based on GAO's March 2011 report on IRS's implementation of the paid preparer requirements and other GAO reports related to paid preparers. Further, GAO identified additional steps IRS has taken to implement the requirements since the March report was issued. GAO discussed the new information with IRS officials, and they concurred with the findings."

DOD Financial Management: Numerous Challenges Must Be Addressed to Achieve Auditability
Testimony issued by the Government Accountability Office with an abstract that begins "As one of the largest and most complex organizations in the world, the Department of Defense (DOD) faces many challenges in resolving serious problems in its financial management and related business operations and systems. DOD is required by various statutes to (1) improve its financial management processes, controls, and systems to ensure that complete, reliable, consistent, and timely information is prepared and responsive to the financial information needs of agency management and oversight bodies, and (2) produce audited financial statements. Over the years, DOD has initiated numerous efforts to improve the department's financial management operations and achieve an unqualified (clean) opinion on the reliability of its reported financial information. These efforts have fallen short of sustained improvement in financial management or financial statement auditability. The Panel requested that GAO provide its perspective on the status of DOD's financial management weaknesses and its efforts to resolve them; the challenges DOD continues to face in improving its financial management and operations; and the status of its efforts to implement automated business systems as a critical element of DOD's Financial Improvement and Audit Readiness strategy."

Climate Change Adaptation: Aligning Funding with Strategic Priorities
Testimony issued by the Government Accountability Office with an abstract that begins "A 2009 assessment by the United States Global Change Research Program (USGCRP) found that many types of extreme weather events, such as heat waves and regional droughts, have become more frequent and intense during the past 40 to 50 years. According to the assessment, changes in extreme weather and climate events will affect many aspects of society and the natural environment, such as infrastructure. In addition, the Department of Defense found that climate change may act as an accelerant of instability or conflict, placing a burden to respond on militaries around the world. According to the National Academies, USGCRP, and others, greenhouse gases already in the atmosphere will continue altering the climate system into the future regardless of emissions control efforts. Therefore, adaptation--defined as adjustments to natural or human systems in response to actual or expected climate change--is an important part of the response to climate change. This testimony addresses (1) the actions federal, state, and local authorities are taking to adapt to climate change; (2) the challenges that federal, state, and local officials face in their efforts to adapt and actions federal agencies could take to help …

Technology Assessment: Explosives Detection Technologies to Protect Passenger Rail
A letter report issued by the Government Accountability Office with an abstract that begins "Passenger rail systems are vital to the nation's transportation infrastructure, providing approximately 14 million passenger trips each weekday. Recent terrorist attacks on these systems around the world--such as in Moscow, Russia in 2010--highlight the vulnerability of these systems. The Department of Homeland Security's (DHS) Transportation Security Administration (TSA) is the primary federal entity responsible for securing passenger rail systems. In response to the Legislative Branch Appropriations Act for fiscal year 2008, GAO conducted a technology assessment that reviews 1) the availability of explosives detection technologies and their ability to help secure the passenger rail environment, and 2) key operational and policy factors that impact the role of explosives detection technologies in the passenger rail environment. GAO analyzed test reports on various explosives detection technologies and convened a panel of experts comprised of a broad mix of federal, technology, and passenger rail industry officials. GAO also interviewed officials from DHS and the Departments of Defense, Energy, Transportation, and Justice to discuss the effectiveness of these technologies and their applicability to passenger rail. GAO provided a draft of this report these departments for comment. Four departments provided technical …

Information Technology: DHS Needs to Improve Its Independent Acquisition Reviews
A letter report issued by the Government Accountability Office with an abstract that begins "Since its creation in 2003, the Department of Homeland Security (DHS) has been developing new information technology (IT) systems to perform both mission-critical and support functions; however, it has faced challenges in developing these systems. One way to manage the inherent risks of developing and acquiring systems is through independent verification and validation (IV&V)--a process conducted by a party independent of the development effort that provides an objective assessment of a project's processes, products, and risks throughout its life cycle and helps ensure that program performance, schedule, and budget targets are met. GAO was asked to determine (1) how DHS's IV&V policies and procedures for IT acquisitions compare with leading practices and (2) the extent to which DHS has implemented IV&V on its large IT system acquisitions. To do so, GAO assessed DHS's policy against industry standards and leading practice guides, as well as analyzed how eight selected IT programs had implemented IV&V."

Combatting Illicit Drugs: DEA and ICE Interagency Agreement Has Helped to Ensure Better Coordination of Drug Investigations
A letter report issued by the Government Accountability Office with an abstract that begins "The 2010 National Drug Threat Assessment stated that the availability of illicit drugs is increasing. The Drug Enforcement Administration (DEA), in the Department of Justice (DOJ), works with Immigration and Customs Enforcement (ICE), within the Department of Homeland Security (DHS), to carry out drug enforcement efforts. DEA and ICE signed a 2009 Interagency Agreement (Agreement) that outlined the mechanisms to provide ICE with authority to investigate violations of controlled substances laws (i.e., cross-designation). The Agreement also required DEA and ICE to deconflict (e.g., coordinate to ensure officer safety and prevent duplicative work) counternarcotics investigations, among other things. GAO was asked to assess the Agreement's implementation. This report addresses the extent to which DEA and ICE have taken actions (1) to implement the Agreement's cross-designation, deconfliction, and information-sharing provisions and (2) to monitor implementation of the Agreement and make needed adjustments. GAO analyzed documents such as the 2009 Agreement, related interagency agreements, and directives to field offices. GAO also interviewed DEA and ICE Headquarters officials as well as management officials and first line supervisors in 8 of the 21 DEA and 8 of 26 ICE field offices, …

Performance Measurement: Better Alignment to Strategic Goals and Data Verification Needed at the Corporation for National and Community Service
A letter report issued by the Government Accountability Office with an abstract that begins "The Corporation for National and Community Service (CNCS) promotes volunteering and civic engagement through a variety of federally funded programs, such as AmeriCorps. In 2009, Congress passed the Serve America Act (Pub. L. No. 111-13), which made substantial changes to CNCS' mission. The Act authorized an increase in the number of service opportunities administered by CNCS, from 88,000 in 2010 to 250,000 by 2017; created new programs; and directed CNCS to focus more on evaluating its programs' performance to ensure cost-effectiveness and the effective use of volunteers, among other factors. To assist the Congress in its oversight role, GAO reviewed: (1) To what extent do the corporation's current performance measures align with the corporation's strategic goals? (2) To what extent do the corporation's performance measures provide a reliable way to assess progress in achieving the corporation's strategic goals? and (3) What progress has the corporation made in developing new performance measures for each of its national service programs?"

Green Information Technology: Agencies Have Taken Steps to Implement Requirements, but Additional Guidance on Measuring Performance Needed
A letter report issued by the Government Accountability Office with an abstract that begins "The federal government's substantial use of information technology (IT) contributes significantly to federal agencies' energy use and environmental impact. To help mitigate this impact, organizations have adopted practices for using computing resources in a sustainable and more environmentally friendly manner-- sometimes referred to as "green IT." These practices include equipment acquisition, use, disposal, and related processes. GAO was asked to (1) determine the extent to which the government has defined policy and guidance on green IT and how selected federal agencies are implementing this policy and guidance, and (2) identify leading green IT practices used by federal agencies, state and local governments, and private-sector organizations. To do this, GAO evaluated federal guidance and policy, as well as guidance and initiatives at selected agencies; identified and characterized efforts in the public and private sectors; and interviewed officials."

Army and Marine Corps Training: Metrics Needed to Assess Initiatives on Training Management Skills
A letter report issued by the Government Accountability Office with an abstract that begins "Over the past decade, Army and Marine Corps forces have deployed repeatedly with limited time between deployments. At their home stations, combat training centers, and other locations, units have focused their limited training time on training for counterinsurgency operations. Prior to deploying, units also conduct a large-scale exercise referred to as a culminating training event. With the drawdown of forces in Iraq, the services have begun to resume training for a fuller range of offensive, defensive, and stability missions. The House report to the National Defense Authorization Act for Fiscal Year 2011 directed GAO to report on the Army's and Marine Corps' abilities to complete training requirements. GAO assessed the extent to which the services' (1) active component forces are completing training prior to the culminating training event and (2) leaders are positioned to plan and manage training as forces resume training for a fuller range of missions. GAO analyzed training requirements and unit training documentation, and interviewed headquarters and unit personnel during site visits between July 2010 and July 2011."

Defense Management: Improved Planning, Training, and Interagency Collaboration Could Strengthen DOD's Efforts in Africa
A letter report issued by the Government Accountability Office with an abstract that begins "When the U.S. Africa Command (AFRICOM) became fully operational in 2008, it inherited well over 100 activities, missions, programs, and exercises from other Department of Defense (DOD) organizations. AFRICOM initially conducted these inherited activities with little change. However, as AFRICOM has matured, it has begun planning and prioritizing activities with its four military service components, special operations command, and task force. Some activities represent a shift from traditional warfighting, requiring collaboration with the Department of State, U.S. Agency for International Development, and other interagency partners. GAO's prior work has identified critical steps and practices that help agencies to achieve success. For this report, GAO was asked to assess AFRICOM in five areas with respect to activity planning and implementation. To do so, GAO analyzed DOD and AFRICOM guidance; observed portions of AFRICOM activities; interviewed officials in Europe and Africa; and obtained perspectives from interagency officials, including those at 22 U.S. embassies in Africa."

Native American Graves Protection and Repatriation Act: After Almost 20 Years, Key Federal Agencies Still Have Not Fully Complied with the Act
A letter report issued by the Government Accountability Office with an abstract that begins "The Native American Graves Protection and Repatriation Act (NAGPRA) required federal agencies and museums to (1) identify their Native American human remains and other objects, (2) try to culturally affiliate them with a present day Indian tribe or Native Hawaiian organization, and (3) repatriate them under the terms in the act. The National NAGPRA office, within the Department of the Interior's National Park Service (NPS), facilitates the government-wide implementation of NAGPRA. GAO was asked to determine, among other things, the (1) extent to which agencies have complied with their NAGPRA requirements, (2) actions taken by National NAGPRA, and (3) extent of repatriations reported by agencies. GAO reviewed records for eight key agencies with significant historical collections, surveyed agencies to obtain repatriation data, and interviewed agency, museum, and tribal officials."

Supplemental Nutrition Assistance Program: Payment Errors and Trafficking Have Declined, but Challenges Remain
Testimony issued by the Government Accountability Office with an abstract that begins "The U.S. Department of Agriculture's (USDA) Supplemental Nutrition Assistance Program (SNAP) is intended to help low-income individuals and families obtain a better diet by supplementing their income with benefits to purchase food. USDA's Food and Nutrition Service (FNS) and the states jointly implement SNAP. Participation in the program has risen steadily over the last decade to an all time high of more than 33 million in fiscal year 2009, providing critical assistance to families in need. This testimony discusses GAO's past work on three issues related to ensuring integrity of the program: (1) improper payments to SNAP participants, (2) trafficking of SNAP benefits, and (3) categorical eligibility for certain individuals or households. This testimony is based on prior GAO reports on categorical eligibility (GAO-07-465), payment errors (GAO-05-245), and food stamp trafficking (GAO-07-53), developed through data analyses, case file reviews, site visits, interviews with officials, and a 50- state survey. GAO also updated data where available and collected information on recent USDA actions and policy changes."

Service-Disabled Veteran-Owned Small Business Program: Preliminary Information on Actions Taken by Agencies to Address Fraud and Abuse and Remaining Vulnerabilities
Testimony issued by the Government Accountability Office with an abstract that begins "The Small Business Administration (SBA) most recently reported in fiscal year 2010 that $10.8 billion of federal contracts were awarded to Service-Disabled Veteran-Owned Small Businesses (SDVOSB). SBA's report also showed that, of this amount, $3.2 billion was for Department of Veterans Affairs (VA) contracts. In 2009 and 2010, GAO reported on weaknesses in fraud-prevention controls that allowed 10 ineligible firms to receive millions of dollars in SDVOSB contracts. GAO was asked to update (1) agency actions in response to prior investigations of 10 case-study firms, the status of prior GAO recommendations, and the status of ongoing Inspector General (IG) investigations, and (2) the status of any new federal contract obligations associated with the case-study firms. This testimony provides preliminary information on GAO's ongoing work. To address these objectives, GAO reviewed prior findings from audits and investigations of the SDVOSB program, and contacted SBA, VA, and agency IG officials for an update on actions taken in response to GAO's prior recommendations and the 10 case-study firms. GAO identified contract obligations awarded to the 10 case-study firms. GAO did not validate representations made by agency officials or determine whether any …

Small Business Administration: Undercover Tests Show HUBZone Program Remains Vulnerable to Fraud and Abuse
Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses the results of our investigation of the Small Business Administration's (SBA) Historically Underutilized Business Zone (HUBZone) program. In fiscal year 2009, federal agencies obligated nearly $3 billion in sole source or set-aside contracts to firms participating in the HUBZone program. Created in 1997, the program provides federal contracting assistance to small businesses located in HUBZones--economically distressed areas with low income levels or high unemployment rates. Qualified businesses in these areas are eligible to bid on federal prime contracts and subcontracts available exclusively to program participants, in addition to benefiting from other contracting preferences. The SBA must certify that a small business meets the following criteria to qualify for the program: the firm must be owned and controlled by one or more U.S. citizens; at least 35 percent of full-time employees must live in a HUBZone; and the principal office, where most qualifying employees work, must be in a HUBZone. According to the SBA's Dynamic Small Business Web site, as of July 2010, 9,300 firms were participating in the program. Over the last 2 years, we have reported on fraud and abuse and other concerns with …

National Security: Interagency Collaboration Practices and Challenges at DOD's Southern and Africa Commands
Testimony issued by the Government Accountability Office with an abstract that begins "Recognizing the limits of military power in today's security environment, the Department of Defense (DOD) is collaborating with other U.S. federal agencies to achieve its missions around the world. DOD's combatant commands, such as U.S. Southern Command (SOUTHCOM) and U.S. Africa Command (AFRICOM), play key roles in this effort. Both aim to build partner nation capacity and perform humanitarian assistance, while standing ready to perform a variety of military operations. Among its missions, SOUTHCOM supports U.S. law enforcement and intelligence agencies in the Americas and Caribbean in disrupting illicit trafficking and narco-terrorism. As DOD's newest command, AFRICOM works with U.S. diplomacy and development agencies on activities such as maritime security and pandemic response efforts. Today GAO issued reports that the subcommittee requested on SOUTHCOM (GAO-10-801) and AFRICOM (GAO-10-794), which in part evaluated how each collaborates with U.S. interagency partners. This testimony summarizes that work and provides observations from ongoing work on U.S. counterpiracy efforts by focusing on 3 key areas essential for interagency collaboration."

Improper Payments: Reported Medicare Estimates and Key Remediation Strategies
Testimony issued by the Government Accountability Office with an abstract that begins "GAO has designated Medicare as a high-risk program because of its size, complexity, and susceptibility to improper payments. In 2010, Medicare covered 47 million elderly and disabled beneficiaries and had estimated outlays of $516 billion. The Centers for Medicare & Medicaid Services (CMS) is the agency in the Department of Health and Human Services (HHS) responsible for administering the Medicare program and leading efforts to reduce Medicare improper payments. This testimony focuses on estimated improper payments in the Medicare program for fiscal year 2010 and the status of CMS's efforts to implement key strategies to help reduce improper payments. This testimony is primarily based on previous GAO reporting related to governmentwide improper payments, Medicare high-risk challenges and program integrity efforts, and CMS's information technology systems intended to identify improper payments. GAO supplemented that prior work with additional information on the nature and extent of Medicare improper payments reported by HHS in its fiscal year 2010 agency financial report. GAO also received updated information from CMS in February 2011 and, in select cases, as of July 2011, on its actions related to relevant laws, regulations, guidance, and open recommendations …

Department of Veterans Affairs: Long-standing Weaknesses in Miscellaneous Obligation and Financial Reporting Controls
Testimony issued by the Government Accountability Office with an abstract that begins "In September 2008, GAO reported internal control weaknesses over the Veteran Health Administration's (VHA) use of $6.9 billion in miscellaneous obligations in fiscal year 2007. In November 2009, GAO reported on deficiencies in corrective action plans to remediate financial reporting control deficiencies. This testimony is based on these previous reports that focused on (1) VHA miscellaneous obligation control deficiencies and (2) Department of Veterans Affairs (VA) financial reporting control deficiencies and VA plans to correct them. For its review of VHA miscellaneous obligations, GAO evaluated VA's policies and procedures and documentation, interviewed cognizant agency officials, and conducted case studies at three VHA medical centers. For its review of financial reporting control deficiencies, GAO evaluated VA financial audit reports from fiscal years 2000 to 2008 and analyzed related corrective action plans."
