Performance Auditing (3rd Edition): Measuring Inputs, Outputs, and Outcomes

New IIA Book co-authored by Auditor Roles Principal Stephen L. Morgan along with Ronnell B. Raaum and Colleen G. Waring

Whether you are new to performance auditing or have years of experience, this book offers you valuable tools to enhance your skills and your office’s performance auditing program, including concrete step-by-step guidance on all aspects of the performance auditing process. For example:

  • 10 Steps for Using Benchmarking in Performance Audits
  • 10 Steps for Audits of Efficiency
  • 10 Steps to Develop Timeliness Measures and Analyze Results
  • 10 Steps for Measuring and Assessing Quality
  • 8 Steps to Quantify the Impact of a Program Intervention (“Program Results”)

Performance auditing promotes best practices in organizations, programs, and services by measuring and reporting on all performance—both good and bad.  As information agents, auditors find ways to improve government operations and results by identifying performance problems, causes, and corrective actions, and providing assurance to stakeholders. This book emphasizes the use of measurement and comparison in performance assessment to help auditors add value by finding ways the organizations and programs they audit can make measurable performance improvements.

Key Updates in the 3rd Edition:

  • References to key U.S. and international performance auditing standards (IPPF, GAGAS, INTOSAI) promulgated by The IIA, U.S. GAO, and INTOSAI.
  • Comprehensive information on managing the audit office to build a solid structural foundation for effective authority, leadership, and operation.
  • Emerging best practices during audit planning to include use of risk and vulnerability assessment. Also includes key steps in conducting initial project-level planning and making a proposal for audit.
