This method ensures that findings are based on factual observations and not subjective opinions.

Question 33: During an audit, an auditee shows the auditor a procedure that was revised last week to address a known gap. The auditor finds no other evidence of the gap. How should this be handled?

Expand the audit to verify the revision across all related processes
Verify the revision is approved and implemented, and consider whether an OFI or observation is more appropriate (Correct answer)
Accept the revision as full closure and move on with no finding
Issue a nonconformity for the prior gap regardless of the revision

Correct answer: Verify the revision is approved and implemented, and consider whether an OFI or observation is more appropriate

The auditor should confirm the revision is properly authorized and in use; if the gap appears resolved, an observation may suffice over a nonconformity.

Question 34: What should be included in an audit report?

Summary of findings only
Scope, evidence, nonconformities, and corrective actions (Correct answer)
Evidence and corrective actions only
The scope and nonconformities only

Correct answer: Scope, evidence, nonconformities, and corrective actions

A comprehensive audit report must clearly define the audit's scope to establish what was examined. It should detail the evidence collected to substantiate all findings, explicitly state any identified nonconformities, and outline the agreed-upon or recommended corrective actions. This ensures the report is complete, transparent, and actionable for all relevant stakeholders.

Question 35: What is the role of root cause analysis in corrective actions?

To evaluate employee performance
To track audit progress
To identify the underlying cause and prevent recurrence (Correct answer)
To monitor customer feedback
