ASQ Certified Quality Technician Questions 4 — Questions and Answers
Question 1: Which document specifies the dimensional, material, and functional requirements that a product must meet?
- Work instruction
- Control plan
- Engineering drawing / specification (Correct answer)
- Quality manual
Correct answer: Engineering drawing / specification
Engineering drawings and specifications define the required dimensions, tolerances, materials, and functional characteristics that a product must conform to.
Question 2: A process produces 45 defects out of 1,000 opportunities. What is the defects per million opportunities (DPMO)?
- 4,500
- 45,000 (Correct answer)
- 450
- 450,000
Correct answer: 45,000
DPMO = (defects / opportunities) × 1,000,000 = (45 / 1,000) × 1,000,000 = 45,000.
Question 3: In FMEA, the Risk Priority Number (RPN) is calculated as:
- Severity + Occurrence + Detection
- Severity × Occurrence × Detection (Correct answer)
- Severity × Occurrence / Detection
- Occurrence × Detection / Severity
Correct answer: Severity × Occurrence × Detection
RPN = Severity × Occurrence × Detection, and it is used to prioritize failure modes for corrective action.
Question 4: Which of the following best describes 'calibration' of a measurement instrument?
- Adjusting the instrument to eliminate all measurement error
- Comparing the instrument's measurements to a known reference standard (Correct answer)
- Determining the repeatability of the instrument
- Replacing worn parts to restore original accuracy
Correct answer: Comparing the instrument's measurements to a known reference standard
Calibration is the process of comparing an instrument's readings to a known reference standard to determine its accuracy and identify any bias.
Question 5: What is the purpose of a corrective action?
- To detect nonconformances before they reach the customer
- To prevent a problem from recurring by eliminating its root cause (Correct answer)
- To sort conforming from nonconforming product
- To document planned improvements
Correct answer: To prevent a problem from recurring by eliminating its root cause
Corrective action aims to permanently eliminate the root cause of a nonconformance to prevent recurrence.
Question 6: Which chart would be most appropriate when monitoring the proportion of defective items in samples of equal size?
- c-chart
- u-chart
- p-chart (Correct answer)
- np-chart
Correct answer: p-chart
The p-chart monitors the proportion (fraction) defective and can be used with both equal and unequal sample sizes.
Question 7: In ISO 9001:2015, what is the focus of the 'risk-based thinking' requirement?
- Eliminating all risks from business processes
- Considering risks and opportunities when planning and implementing the QMS (Correct answer)
- Documenting every identified risk in a formal register
- Transferring risk to suppliers through contracts
Correct answer: Considering risks and opportunities when planning and implementing the QMS
ISO 9001:2015 requires organizations to consider risks and opportunities proactively throughout their QMS planning and operations rather than eliminating all risk.
