Final answer:
Tagging and lagging is not a recognized computer-assisted audit technique, while test data, integrated test facility, and program analysis are all CAATs used by auditors.
Step-by-step explanation:
The question asks to identify which option is not a computer-assisted audit technique (CAAT). The options given are: A) Test data, B) Tagging and lagging, C) Integrated test facility, and D) Program analysis. The term computer-assisted audit techniques refers to methods auditors use to analyze and evaluate data during an audit, relying on the use of computers.
Option A) Test data is a CAAT in which auditors insert fictitious transactions into a client's software system to test the software's controls and processing. Option C) Integrated test facility is also a CAAT, wherein auditors create a simulated environment within the client's operational system to test controls during normal operations.
Option D) Program analysis involves tools and techniques used to analyze the code of computer programs for errors or vulnerabilities, and thus can be considered a form of CAAT.
In contrast, B) Tagging and lagging is not a recognized computer-assisted audit technique. It appears to be a made-up term or one that is not associated with the standard practices in auditing.
