- A formal complaint submitted by a customer to management
- The structured process of capturing customer expectations and requirements (Correct answer)
- A customer satisfaction survey administered annually
- Verbal feedback given during product demonstrations
Correct answer: The structured process of capturing customer expectations and requirements
VOC is a structured process for capturing customer needs, expectations, and preferences to drive quality improvement.
Question 2: In the context of quality costs, which category includes costs spent on preventing defects from occurring?
- Appraisal costs
- Internal failure costs
- External failure costs
- Prevention costs (Correct answer)
Correct answer: Prevention costs
Prevention costs are investments made to prevent defects from occurring, such as training and process design.
Question 3: A scatter diagram showing points that trend upward from left to right indicates:
- A negative correlation between two variables
- No relationship between the two variables
- A positive correlation between two variables (Correct answer)
- A cause-and-effect relationship proven statistically
Correct answer: A positive correlation between two variables
An upward-trending scatter diagram indicates a positive correlation—as one variable increases, the other tends to increase.
Question 4: Which principle states that roughly 80% of effects come from 20% of causes?
- Normal distribution principle
- Pareto principle (Correct answer)
- Central limit theorem
- Rule of seven
Correct answer: Pareto principle
The Pareto principle (80/20 rule) states that a vital few causes are responsible for the majority of effects or defects.
Question 5: Total Quality Management (TQM) differs from traditional quality control primarily because TQM:
- Focuses exclusively on final product inspection

- c chart
