The benefits of following the Global Internal Audit Standards™

Following the Standards gives internal auditors a ‘gold standard’ of best practice. Externally, it shows auditors, your investors and the people who use your company’s services that you have a robust approach to internal controls and ethics. Internally, it helps to clarify the importance of internal audit and a commitment to high standards.

  • Demonstrate high standards
  • Boost internal audit’s reputation
  • Align to the company’s strategic goals

Create a culture of good governance

Internal audit plays a crucial role in good governance. This involves taking an objective approach to their work, and being able to highlight any unethical behaviors within the company. The IIA Standards support this with a framework for reporting information in a transparent way and keeping adequate audit trails.
