The system generates a report of any errors or unusual situations identified during transaction processing. This report is reviewed, and any items are resolved in a timely manner, and the resolution is documented by notations made on the report.

Consider the four methods of testing the operating effectiveness of controls (inquiry, observation, document examination, and re-performance). For this control, provide an example of how Mark's audit team might choose to test the operating effectiveness of the control using the four methods of test of controls (e.g., how would the audit team use inquiry, observation, document examination, and re-performance to test control #1, the generation and review of the system log?). [Note: Not all types of tests of controls will be appropriate for testing all the controls.]
