Final answer:
The control plan of retrieving customer data via account numbers addresses multiple operational goals but does not directly ensure input accuracy, which relies on the correct account numbers being entered.
Step-by-step explanation:
The control plan that involves a sales representative entering the customer's account number so the system can retrieve data does not directly address the control goal to ensure input accuracy. This process helps with ensuring efficient employment of resources, ensuring the effectiveness of operations through timeliness, and ensuring update completeness.
However, input accuracy depends on whether the account number entered by the representative is correct. If the wrong account number is inputted, the retrieved data will be incorrect regardless of the control plan's efficiency and timeliness.
