According to the Institute of Internal Auditors (IIA) standards and guidance, the board of an organization defines the overall responsibilities and expectations of the internal audit activity, including its role in providing consulting services. This oversight aligns with the governance role of the board to ensure that the internal audit activity conforms to the standards and adds value to the organization. The internal audit activity may provide consulting services that are advisory in nature and agreed upon with management, but it is the board that sets the overarching governance framework.References: Institute of Internal Auditors (IIA) - International Professional Practices Framework (IPPF)
