Testimony issued by the Government Accountability Office with an abstract that begins "Performance audits as well as traditional financial and compliance audits are essential tools that national audit offices have to help their respective governments identify and address challenging national and global problems. Performance auditing provides objective analysis so that management and those charged with governance and oversight can use the information to improve program performance and operations, reduce costs, facilitate decision making by parties with responsibility to oversee or initiate corrective action, and contribute to public accountability."
