A successful internal audit program is an essential tool for determining how well an organization’s processes and controls are functioning. It can identify high-risk areas and determine how well existing controls are mitigating risks. In the Internal Auditing Guidebook, we cover all aspects of the internal auditing function, including governance, risk management, internal controls, fraud prevention and detection, audit evidence, audit sampling, data analytics, how to conduct engagements, and much more. This book is designed to assist in the development of a fine-tuned internal audit department that can help to minimize risks and provide valuable consulting advice to every area of a business.
