A healthcare organization's chief audit executive (CAE) noted that the organization's IT team relies heavily on a vendor. Therefore an IT vendor assessment review was added to the annual audit plan. During the review, the audit team discovered that the vendor had not been performing proper monitoring to ensure that the subcontractors it hired comply with the organization requirements. The organization's chief information officer (ClO) does not agree with the audit team's recommendation for the IT team to monitor the compliance level of vendor subcontractors. How should the audit team proceed to resolve this situation?
