This document discusses project auditing, including what a project audit is, its benefits, how to judge a project's success or failure, determining project objectives, the contents and format of a project audit, and the responsibilities of an auditor. A project audit is a formal inquiry into any aspect of a project that can help identify problems, improve performance, and evaluate the project team. Key factors in differentiating success from failure are objective design and scope, experienced personnel, appropriate authority, and clear accountability. Project audits should cover the current status, future status, critical tasks, risks, lessons for other projects, and audit limitations.
