Book excerpt: Crossover of Audit and Evaluation Practices brings together academic analysis with insights from practitioners to discuss the potential for collaboration in audit and evaluation practices between three professional disciplines. Clearly written and thoughtfully organized, this volume is structured in three parts to deal with theory, practice issues and how the practices have worked together. • Part One provides definitions of performance audit, internal audit and program evaluation. • Part Two addresses several challenges that professionals face in applying these standards and principles. • Part Three contains examples of organizational collaboration between the practices, how they have worked together and the lessons that were learned from that experience. Specific cases from the Government Accountability Office, and UNESCO, UNDP and Inter-Americas Development Bank illustrate what has worked or not and suggest reasons why. Crossover of Audit and Evaluation Practices offers even the most skilled and experienced professional insight on how to bridge some of the divides. It will help generate a better understanding of the activities and services that are either imposed on them or are freely available and help to stimulate their optimal use.
