What Is Internal Auditing and What Do Auditors Do?


The Institute of Internal Auditors has developed explanations of what internal auditors do. Below are excerpts from their publication: All in a Day’s Work: A Look at the Varied Responsibilities of Internal Auditors


What Is Internal Auditing?

Internal auditing is an independent, objective assurance and consulting activity designed to add value and improve an organization’s operations.


Who Are Internal Auditors?

Internal auditors are explorers, analysts, problem-solvers, reporters, and trusted advisors. They bring objectivity and a variety of skills and expertise to the organization. They come from diverse areas such as finance, operations, IT, and engineering. Today’s internal audit professionals are revered for their critical thinking and communication skills, as well as their general IT and industry-specific business knowledge. Still, people often confuse internal auditors with accountants or external auditors (entities the organization engages to provide an annual review of the financial statements). The differences are significant.
