What must the auditor consider in order to mitigate audit risks and obtain reasonable assurance?

Comprehensive and Detailed In-Depth Explanation:

Auditors must focus on key processes that impact QMS effectiveness to ensure audit risks are minimized.

Clause References:

ISO 19011:2018, Clause 6.3 – Managing Audit Risk: Auditors should prioritize critical processes to obtain reasonable assurance.

Why is the Correct Answer A?

Some processes are critical (e.g., production quality, customer complaints handling).

If these material processes fail, the QMS could collapse.

Why are the Other Options Incorrect?

B (Needs of internal parties) → Important, but not the primary focus for reducing audit risk.

C (Previous audit results) → Useful for improvement but does not directly reduce current audit risks.

D (Financial risks) → ISO 9001 focuses on quality risks, not financial risks.
