QUALITY ENGINEERING EXAM
2025 QUESTIONS AND ANSWERS
Specifications of quality characteristics - ....ANSWER ...-Target or nominal values:
desired value
- Lower specification limit: smallest allowable value - Upper specification limit: largest
allowable value
Nonconforming product: - ....ANSWER ...-fails to meet one or more specifications
nonconformity - ....ANSWER ...-specific type of failure
Defect: - ....ANSWER ...-A nonconformity that is serious enough to significantly
affect the safe or effective use of the product.
Six Sigma/DMAIC - ....ANSWER ...-variation reduction
Six Sigma: - ....ANSWER ...-A framework to improve financial
performance by improving quality
By how much must we improve quality (eg, reduce ppm defective) each year to improve
from our current sigma level to our goal sigma level in a given number of years? -
....ANSWER ...-A: Goal ppm defective =
Current ppm defective (1-improvement rate)# of years

• SIPOC diagram (or other process map)
Project Charter - ....ANSWER ...-Project Scope, Opportunity, Project Status,
Actions/Open Issues
SIPOC Diagram - ....ANSWER ...-Suppliers, Inputs, Process, Output, Customers
Tollgates - ....ANSWER ...-Review process in-between each step of DMAIC to
make sure ready for the next step
Measure - ....ANSWER ...-What is the current state? Purpose, Value Stream Map,
Variables of Interest, Data, Tools, Measurement
Analyze - ....ANSWER ...-What is the root cause of the issue? 1st step often
brainstorming. Determine cause and effect relationships and Sources of variability.
