Quality Auditor Certification Corrective Actions 3 — Questions and Answers
Question 1: The '5 Whys' technique is most effective when the problem being analyzed is:
- Highly complex with many interacting variables
- Relatively straightforward with a clear cause-and-effect chain (Correct answer)
- Statistical in nature requiring data collection
- Caused by external supplier failures
Correct answer: Relatively straightforward with a clear cause-and-effect chain
The 5 Whys works best for problems with a linear or straightforward cause-and-effect path rather than complex multi-variable issues.
Question 2: Under ISO 9001:2015, corrective action records must be retained as:
- Documented information (records) (Correct answer)
- Management review inputs only
- Internal audit reports
- Customer complaints logs
Correct answer: Documented information (records)
ISO 9001:2015 clause 10.2.2 requires organizations to retain documented information as evidence of the nature of nonconformities and corrective actions taken.
Question 3: Which of the following best describes a 'preventive action' compared to a 'corrective action'?
- Preventive action addresses a current nonconformance; corrective action prevents future ones
- Preventive action addresses a potential nonconformance; corrective action addresses an actual one (Correct answer)
- Both terms are interchangeable under ISO 9001:2015
- Preventive action is required by regulation; corrective action is voluntary
Correct answer: Preventive action addresses a potential nonconformance; corrective action addresses an actual one
Corrective action eliminates the cause of an existing nonconformance, while preventive action eliminates the cause of a potential nonconformance before it occurs.
Question 4: A quality team uses Failure Mode and Effects Analysis (FMEA) during corrective action planning. The primary benefit of this approach is:
- It calculates the financial cost of the nonconformance
- It prioritizes risks by evaluating severity, occurrence, and detectability (Correct answer)
- It assigns blame to specific departments
- It replaces the need for a root cause analysis
Correct answer: It prioritizes risks by evaluating severity, occurrence, and detectability
FMEA uses a Risk Priority Number (RPN) based on severity, occurrence, and detection ratings to prioritize which failure modes require immediate corrective action.
Question 5: During effectiveness review of a corrective action, what type of evidence is MOST objective?
- Verbal confirmation from the process owner
- Updated procedure documents with revision history
- Statistical process data showing the issue has not recurred (Correct answer)
- Employee satisfaction survey results
Correct answer: Statistical process data showing the issue has not recurred
Statistical process data provides measurable, quantifiable evidence that the corrective action eliminated the nonconformance and prevented recurrence.
Question 6: What is the purpose of a 'lessons learned' step at the end of a corrective action process?
- To assign disciplinary actions to responsible employees
- To apply knowledge gained to similar processes or products to prevent related issues (Correct answer)
- To determine warranty claim eligibility
- To escalate unresolved issues to senior management
Correct answer: To apply knowledge gained to similar processes or products to prevent related issues
Lessons learned capture insights from the corrective action to proactively improve other similar areas within the quality management system.
Question 7: Which of the following is an example of a systemic corrective action?
- Re-inspecting all products from a defective batch
- Retraining all operators on a procedure that was found to be unclear across multiple sites (Correct answer)
- Scrapping a single defective part
- Issuing a verbal warning to an operator who made an error
Correct answer: Retraining all operators on a procedure that was found to be unclear across multiple sites
Retraining all operators on a clarified procedure addresses the systemic root cause of unclear work instructions across multiple locations.
