directly at the outlets, with large orders sent to a central
production facility. The MOST appropriate control to ensure

processed would be to:
A. send and reconcile transaction counts and totals.

Answer: A
Sending and reconciling transaction totals not only ensures
that the orders were received, but also processed by the
central production location. Transmission back to the local
site confirms that the central location received it, but not
that they have actually processed it. Tracking and
accounting for the numerical sequence only confirms what
orders are on hand, and not whether they actually have been
completed. The use of parity checking would only confirm
that the order was not changed during transmission.
