Quality Auditor Certification Reporting 4 — Questions and Answers
Question 1: When a quality report uses a Pareto chart, the underlying principle being applied is:
- All defects contribute equally to quality problems
- Approximately 80% of problems stem from 20% of causes (Correct answer)
- Data must be sorted alphabetically before charting
- Sample sizes must exceed 100 for valid results
Correct answer: Approximately 80% of problems stem from 20% of causes
The Pareto principle (80/20 rule) states that roughly 80% of effects come from 20% of causes, helping prioritize improvement efforts.
Question 2: A quality auditor finds that an organization's management review records are incomplete. This would typically be reported as:
- A major nonconformance against ISO 9001 clause requirements (Correct answer)
- An external failure cost
- An opportunity for improvement only
- A warranty claim
Correct answer: A major nonconformance against ISO 9001 clause requirements
Incomplete management review records represent a failure to meet a specific ISO 9001 clause requirement, constituting a major nonconformance.
Question 3: In quality reporting, 'sigma level' is used to describe:
- The number of auditors assigned to a project
- The process performance in terms of defects per million opportunities (Correct answer)
- The frequency of management review meetings
- The ratio of prevention to appraisal costs
Correct answer: The process performance in terms of defects per million opportunities
Sigma level expresses process capability as defects per million opportunities (DPMO), with Six Sigma equaling 3.4 DPMO.
Question 4: Which type of quality report compares current performance against a pre-established baseline or target?
- Benchmark report
- Audit trail report
- Variance report (Correct answer)
- Traceability report
Correct answer: Variance report
A variance report compares actual performance against planned targets or baselines, highlighting deviations that require attention.
Question 5: When reporting on a process using an X-bar and R chart, what does the R chart specifically monitor?
- The process average (mean)
- The process variation (range within subgroups) (Correct answer)
- The proportion of defective units
- The number of defects per inspection unit
Correct answer: The process variation (range within subgroups)
The R (range) chart monitors within-subgroup variation, while the X-bar chart monitors the subgroup averages.
Question 6: An audit report's 'distribution list' specifies:
- The statistical distribution of defects found
- Who receives copies of the completed audit report (Correct answer)
- The geographic areas covered by the audit
- The distribution of audit hours by process
Correct answer: Who receives copies of the completed audit report
The distribution list identifies all parties who should receive copies of the audit report, ensuring proper communication to stakeholders.
Question 7: A quality manager notices that the number of customer complaints has decreased while internal rejection rates have increased. What does this most likely indicate?
- The quality system is performing better overall
- Internal detection is improving, catching more defects before shipment (Correct answer)
- Customer satisfaction metrics are being falsified
- The complaint handling process has become ineffective
Correct answer: Internal detection is improving, catching more defects before shipment
Rising internal rejections with falling complaints typically indicates that the internal inspection process is catching more defects before they reach customers.
