Product Management Product Quality Management 3 — Questions and Answers
Question 1: In quality management, what is the purpose of a 'control chart'?
- Track feature request priority
- Monitor process variation over time to detect anomalies (Correct answer)
- Rank customer complaints by severity
- Estimate story points
Correct answer: Monitor process variation over time to detect anomalies
Control charts plot process metrics over time with upper and lower control limits to distinguish normal variation from significant anomalies.
Question 2: Which quality management standard is most commonly referenced for product and organizational quality management systems?
- ISO 9001 (Correct answer)
- PCI-DSS
- GDPR
- SOC 2
Correct answer: ISO 9001
ISO 9001 is the internationally recognized standard for quality management systems, specifying requirements for consistent product and service quality.
Question 3: A PM discovers that 30% of newly shipped features have bugs found by customers rather than QA. What does this indicate?
- Low defect density
- High defect escape rate (Correct answer)
- Positive MTBF trend
- Strong quality assurance process
Correct answer: High defect escape rate
Defect escape rate measures how many defects pass through internal quality checks and reach customers, with a high rate signaling weak QA processes.
Question 4: Which technique involves systematically releasing a product to a small percentage of users first to limit quality risk?
- A/B testing
- Canary release (Correct answer)
- Waterfall deployment
- Alpha testing
Correct answer: Canary release
A canary release deploys a new version to a small subset of users first, allowing teams to detect quality issues before full rollout.
Question 5: What is 'technical debt' in the context of product quality?
- The budget allocated for QA testing tools
- Shortcuts taken in development that increase future maintenance cost (Correct answer)
- A metric for measuring code coverage
- The cost of third-party integrations
Correct answer: Shortcuts taken in development that increase future maintenance cost
Technical debt refers to the implied future rework caused by choosing expedient solutions now instead of better, more time-consuming approaches.
Question 6: A PM wants to ensure a feature works correctly under extreme load before launch. Which type of testing is MOST appropriate?
- Usability testing
- Stress testing (Correct answer)
- Regression testing
- Exploratory testing
Correct answer: Stress testing
Stress testing evaluates how a system behaves under extreme conditions or loads beyond its normal operating capacity.
Question 7: When using the DMAIC framework for quality improvement, what does the 'M' stand for?
- Manage
- Measure (Correct answer)
- Mitigate
- Monitor
Correct answer: Measure
In Six Sigma's DMAIC, 'Measure' involves collecting data on the current process to establish a baseline before improvements are made.
