What did the audit team use to assess the implementation of AI-related controls, verify compliance...

In Scenario 6, it is clearly stated:

“They also used sampling and technical verification to assess the implementation of AI-related controls, verify compliance with established procedures, and identify any gaps in adherence to the AIMS requirements.”

Sampling and technical verification are considered evidence collection tools used during audits. These tools enable auditors to validate the effectiveness of implemented controls by selectively reviewing samples, performing walkthroughs, and technically verifying how AI systems function in real-life scenarios.

According to ISO 19011:2018, Clause 6.5.5, audit evidence may be obtained through tools such as:

* Interviews

* Observations

* Technical testing

* Sampling

* Documentation review

This confirms that the audit team used “evidence collection tools” — specifically sampling and technical verification — to perform their assessments.
