As one of the largest and most complex organizations in the world, the Department of Defense (DOD) faces many challenges in resolving its pervasive and long-standing financial management and related business operations and systems problems. 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. DOD has initiated numerous efforts over the years to improve the department's financial management operations and ultimately achieve unqualified (clean) opinions on the reliability of reported financial information. The Subcommittee has asked GAO to provide its perspective on DOD's current efforts to address its financial management weaknesses and achieve auditability, including the status of its Enterprise Resource Planning (ERP) system implementations. GAO's testimony is based on its prior work related to DOD's financial improvement and audit readiness strategy and related activities, including its ERP implementation efforts.
