1. In a full factorial DOE with 3 factors at 2 levels each, how many experimental runs are required? → 8 runs
2. In SPC, a 'run of 8 consecutive points on one side of the centerline' is an example of: → A signal of special cause variation
3. In a QMS audit context, an 'observation' differs from a 'nonconformity' because it: → Is a concern or opportunity for improvement that does not yet violate a requirement
4. Which quality management principle emphasizes that sustained success comes from managing relationships with interested parties? → Relationship management
5. Which of the following is NOT a preventative cost? → Calibrating test equipment
6. Failure Mode, Effects, and Criticality Analysis (FMECA) extends FMEA by adding: → A criticality analysis that quantifies the probability and severity of each failure mode
7. Main effects are not confused with any other main effects at the lowest design resolution, which is known as: → Resolution III design
8. A ___ is a particular kind of line graph used to evaluate a process's stability. → Control chart
9. In Gauge R&R terminology, 'appraiser variation' (AV) corresponds to: → Reproducibility — the variation introduced by different operators using the same gauge
10. Which sampling plan standard is most commonly referenced for attribute inspection in US manufacturing? → ANSI/ASQ Z1.4
11. A coordinate measuring machine (CMM) is used in manufacturing quality control primarily for: → Precise dimensional measurement of parts in three-dimensional space
12. In audit terminology, what is an 'audit scope'? → The extent and boundaries of the audit, including locations, processes, and time period
13. Which of the following would a high-quality training effort's desired results NOT include? → A higher price for high-quality outcomes
14. When parts are destroyed during the measurement process, the appropriate MSA study design is: → A nested (destructive) Gauge R&R study where parts are nested within operators
15. The %P/T ratio in measurement systems analysis compares: → Measurement system variation to the engineering specification tolerance
16. The primary purpose of a calibration system in a quality management program is to: → Provide traceability of measurement results to national or international standards
17. In quality management, 'benchmarking' is best defined as: → Comparing processes and performance metrics to industry best practices or competitors
18. What is the primary purpose of a Fault Tree Analysis (FTA)? → To identify combinations of events that could lead to a top-level undesired event
19. Compared to the Average and Range method, the ANOVA method in Gauge R&R analysis provides the additional ability to: → Detect and quantify the operator-by-part interaction effect
20. What is the primary output of a Process Approach in quality management? → Understanding interrelated processes as a system that contributes to effectiveness
21. Which reliability growth model is commonly used to track and predict reliability improvement during development testing? → Duane/AMSAA model
22. What strategy is BEST for developing training materials on performance gaps? → Examine an activity log
23. According to the AIAG MSA manual, a Gauge R&R result is generally considered acceptable when % Gauge R&R is: → Less than 30%, where under 10% is ideal and 10–30% may be acceptable based on application
24. Which risk management strategy accepts a risk without taking action to reduce it? → Risk acceptance
25. In a Gauge R&R study, 'repeatability' refers to variation caused by: → The same operator using the same measurement system repeatedly on the same part
26. A third-party audit is typically performed by: → An independent certification body to grant or maintain certification
27. Which audit evidence is considered most objective and reliable? → Physical observation of a process in action
28. Which type of variation is inherent to a stable process and cannot be eliminated without changing the process itself? → Common cause variation
29. What is the purpose of a Quality Function Deployment (QFD) House of Quality? → Translating customer requirements into technical product characteristics
30. What is meant by 'design redundancy' as a reliability strategy? → Providing backup components or systems so the system functions if one component fails
