ASQ Certified Quality Process Analyst & Improvement Associate 3 — Questions and Answers
Question 1: When performing a Measurement System Analysis (MSA), 'reproducibility' refers to:
- Variation in measurements taken by the same operator on the same part
- Variation in measurements taken by different operators using the same gauge (Correct answer)
- The ability of the gauge to detect small differences
- The long-term stability of a measuring instrument
Correct answer: Variation in measurements taken by different operators using the same gauge
Reproducibility (also called appraiser variation) is the variation in measurements when different operators measure the same part with the same instrument.
Question 2: Which lean concept focuses on producing only what the next process step needs, exactly when it is needed?
- 5S
- Poka-yoke
- Just-in-Time (JIT) (Correct answer)
- Kaizen
Correct answer: Just-in-Time (JIT)
Just-in-Time (JIT) is a pull-based production strategy that minimizes inventory by supplying the right item, at the right time, in the right quantity.
Question 3: A scatter diagram is used primarily to:
- Track defects over time on a timeline
- Rank causes from most to least frequent
- Explore the relationship between two variables (Correct answer)
- Identify the steps and decision points in a process
Correct answer: Explore the relationship between two variables
A scatter diagram plots pairs of data points to visually reveal whether a correlation exists between two variables.
Question 4: In quality management, 'VOC' stands for:
- Validation of Control
- Verification of Compliance
- Voice of the Customer (Correct answer)
- Value of Capability
Correct answer: Voice of the Customer
Voice of the Customer (VOC) is a research process used to capture customer requirements, expectations, preferences, and aversions.
Question 5: Which of the following BEST describes a Type I error in hypothesis testing?
- Failing to detect a real process shift
- Rejecting the null hypothesis when it is actually true (Correct answer)
- Accepting a bad lot of product
- Underestimating the process standard deviation
Correct answer: Rejecting the null hypothesis when it is actually true
A Type I error (alpha risk) occurs when you reject a true null hypothesis — concluding an effect exists when it does not.
Question 6: Which of the following is an example of 'internal failure cost' in the Cost of Quality framework?
- Customer warranty claims
- Incoming inspection of raw materials
- Scrap and rework before product leaves the facility (Correct answer)
- Training employees on quality procedures
Correct answer: Scrap and rework before product leaves the facility
Internal failure costs occur when defects are found before delivery to the customer, including scrap, rework, and downtime.
Question 7: A poka-yoke device is designed to:
- Track defect trends over time using statistical methods
- Prevent errors or make them immediately obvious so they cannot pass undetected (Correct answer)
- Prioritize defects for root cause analysis
- Standardize work instructions across multiple shifts
Correct answer: Prevent errors or make them immediately obvious so they cannot pass undetected
Poka-yoke (mistake-proofing) uses physical or procedural mechanisms to prevent defects from occurring or being passed to the next step.
