Organizational independence for the internal audit activity is best evidenced when the chief audit executive (CAE) reports functionally and administratively to the CEO. Functional reporting to the CEO or equivalent position ensures that the internal audit activity has direct access to top management, which supports its independence and the ability to carry out audits without undue influence from management. Administrative reporting to the CEO also helps align the internal audit function's objectives with those of top management, reinforcing its autonomy and authority within the organization.References: IIA's International Standards for the Professional Practice of Internal Auditing regarding organizational independence.

An example of the chief audit executive (CAE) demonstrating due professional care is by assessing the audit staff's knowledge and skills annually to determine whether additional resources are needed to fulfill the internal audit plan. This practice ensures that the internal audit team is adequately equipped in terms of skills and competencies to meet the organization's audit needs effectively and professionally.References: Institute of Internal Auditors (IIA) - International Professional Practices Framework (IPPF)
