Q1.
In a manufacturing process, a quality auditor must verify the calibration status of a digital
torque wrench used for final assembly. The wrench has a stated accuracy of ±2% of
reading. During calibration, the reference standard has an uncertainty of ±0.5% (k=2). The
measured error at a critical torque value is +1.8% of reading. Which statement best
reflects the auditor's conclusion regarding the wrench's conformance to its specification?
A. The wrench is out of tolerance because B. The wrench is in tolerance because the
the measured error exceeds the stated measured error is within the stated
accuracy. accuracy.
C. The wrench's conformance cannot be D. The wrench is out of tolerance because
determined without accounting for the total uncertainty exceeds the accuracy.
measurement uncertainty.
Correct: C - The wrench's conformance cannot be determined without accounting for
measurement uncertainty.
Rationale:Calibration decisions must incorporate measurement uncertainty. The measured
error of +1.8% plus the reference uncertainty of ±0.5% gives a range of 1.3% to 2.3%, which
overlaps the ±2% limit. Thus, conformance is indeterminate; a guard band or decision rule is
needed. Options A and B ignore uncertainty, while D misinterprets the uncertainty magnitude.
Q2.
An auditor is evaluating a supplier's corrective action system. The supplier has
documented a corrective action for a major nonconformance, but the root cause analysis
used only a 5-Why technique and did not consider process interactions. Which action by
the auditor is most appropriate?
A. Accept the corrective action since 5-Why B. Request additional evidence that the root
is a recognized root cause analysis tool. cause analysis considered systemic factors
and process interactions.
C. Issue a new nonconformance because D. Recommend the supplier use a fishbone

nonconformances.
Correct: B - Request additional evidence that the root cause analysis considered systemic
factors and process interactions.

Rationale: A robust root cause analysis should consider systemic and interactive factors,
especially for major nonconformances. The auditor must verify that the analysis is sufficiently
comprehensive; 5-Why may be appropriate but must be validated for depth. Option A is too
lenient, C is overly prescriptive, and D focuses on a specific tool rather than the adequacy of
the analysis.
Q3.
An auditor is planning a process audit of a high-volume call center. The process has a low
defect rate but high variability in handling time. Which sampling strategy would provide
the most statistically valid estimate of the process performance?
A. Judgment sampling of calls from the most B. Convenience sampling of calls from the
experienced agents. first hour of the day.
C. Stratified random sampling by agent shift D. Haphazard sampling of calls throughout
and call type. the week.
Correct: C - Stratified random sampling by agent shift and call type.
Rationale:Stratified random sampling ensures representation across key subgroups (shifts,
call types) and reduces sampling error, yielding a more valid estimate of process
performance. Judgment, convenience, and haphazard sampling are non-probabilistic and
introduce bias, making statistical inference invalid.
Q4.
An auditor is assessing the effectiveness of a training program for a newly implemented
quality management system. Which combination of metrics would provide the most
balanced evaluation of training effectiveness?
A. Number of employees trained and B. Training cost per employee and trainer
training hours per employee. satisfaction ratings.
C. Post-training test scores and on-the-job D. Attendance rate and number of training
performance indicators. sessions conducted.
Correct: C - Post-training test scores and on-the-job performance indicators.
Rationale:Effective training evaluation should measure learning (test scores) and application
(on-the-job performance). This aligns with Kirkpatrick's levels 2 and 3. Other options measure
inputs or reactions, which do not directly assess effectiveness.
Q5.
An internal auditor is reviewing a supplier's quality data to determine if a corrective action
was effective. The supplier implemented a new inspection procedure and provided data
for 30 days. Which statistical method is most appropriate to determine if the defect rate
has significantly decreased?
