In this scenario, the new recruit has a potential conflict of interest due to her recent role in the finance department. To maintain the objectivity and independence required by the IIA Standards, it is essential to prevent any actual or perceived bias in the audit process. Assigning the new auditor to assist with developing the audit program, but ensuring that the execution of the program is handled by other audit staff (Option B), is the most appropriate approach. This ensures her expertise is utilized without compromising the integrity of the audit. Standard 1130: Impairment to Independence or Objectivity requires auditors to avoid auditing areas where they have recently worked or where personal relationships could impair their objectivity.
