There are many more positive examples of performance improvement & accountability than mentioned in Barrett & Greene's article. See www.AuditorRoles.org for roles & practices government auditors have been playing to improve performance & accountability. Note that the "Auditor Roles in Performance Measurement Project" at that site does not only has examples of performance auditing of specific programs, but also auditing the underlying performance management systems (or lack of same) that government agencies use to manage performance. And also to audit the relevance & reliability of performance measures & data.
