An AI auditor is reviewing evidence that an organization's AI model governance practices comply with their stated policy. Which audit evidence is MOST persuasive for demonstrating that model validation independence is maintained?
Select an answer to reveal the explanation.
Short Explanation
Here's the deal — signed validation reports from validators who are demonstrably separate from development, plus work papers showing independent testing on their own systems, give you direct evidence that validation actually happened independently. Audit evidence has to be sufficient, reliable, and relevant, and that combination shows real execution, not just paperwork.
Full Explanation
The correct evidence is validation reports signed by validators who are demonstrably separate from development team members, with validation work papers showing independent testing and analysis performed on the validators' own systems, because audit evidence must be sufficient, reliable, and relevant. Signed reports plus work papers showing actual independent testing on validators' own infrastructure provide direct evidence of independent execution. An organizational chart showing separate reporting shows structural independence but not operational independence. The policy document requiring independent validation is a process control, not evidence of compliance. The Chief Risk Officer attestation is management representation, the least reliable audit evidence because it relies on the auditee's assertion.
