Final answer:
The Area Organization Audit (AO) is generally completed on-site to allow auditors to directly assess operational practices and interact with staff for a thorough examination.
Step-by-step explanation:
The Area Organization Audit (AO) is typically completed on-site. This is because the on-site environment allows for a direct investigation and assessment of operational practices, employee behaviors, and inventory management, which are all vital for a comprehensive audit. To ensure accuracy and effectiveness, auditors often need to physically inspect the facilities and interact with staff, which is why a virtual audit may not provide the same level of depth and detail required.
