Emphasizing the review of fieldwork completed by internal auditors is crucial for maintaining objectivity. This practice ensures that work is independently checked, helping to prevent bias or errors in the audit process. Regular review by a different auditor or a supervisor can help maintain objectivity and adherence to auditing standards.
