Project Management Project Quality Management 2 — Questions and Answers
Question 1: Which quality management tool uses a visual representation to show the relationship between an effect and its potential causes?
- Pareto chart
- Fishbone diagram (Correct answer)
- Control chart
- Scatter diagram
Correct answer: Fishbone diagram
The fishbone (Ishikawa) diagram visually maps potential causes of a problem to identify root causes.
Question 2: What does 'cost of quality' (COQ) include?
- Only the cost of defects found by customers
- Only the cost of testing and inspection
- All costs incurred to prevent failures plus costs from failures (Correct answer)
- Only the cost of quality audits
Correct answer: All costs incurred to prevent failures plus costs from failures
COQ encompasses both conformance costs (prevention, appraisal) and non-conformance costs (internal and external failures).
Question 3: During which process are quality metrics defined for use later in the project?
- Control Quality
- Manage Quality
- Plan Quality Management (Correct answer)
- Perform Integrated Change Control
Correct answer: Plan Quality Management
Plan Quality Management defines the quality metrics that will be measured and monitored throughout the project.
Question 4: A project manager notices that 80% of defects come from 20% of identified causes. Which tool best supports this finding?
- Control chart
- Histogram
- Pareto chart (Correct answer)
- Run chart
Correct answer: Pareto chart
The Pareto chart ranks causes by frequency, visually supporting the 80/20 rule to prioritize defect reduction efforts.
Question 5: What is the primary purpose of a quality audit?
- To penalize team members who produce defects
- To identify inefficient and ineffective policies and recommend improvements (Correct answer)
- To approve deliverables for customer acceptance
- To update the project schedule based on defects found
Correct answer: To identify inefficient and ineffective policies and recommend improvements
Quality audits are structured reviews to identify non-compliant processes and recommend corrective actions.
Question 6: Which of the following best describes 'prevention over inspection' in quality management?
- Spending more time testing finished products than planning
- Building quality into the process rather than detecting defects afterward (Correct answer)
- Hiring external inspectors to review all deliverables
- Skipping the planning phase to save time for testing
Correct answer: Building quality into the process rather than detecting defects afterward
Prevention over inspection means designing processes to avoid defects rather than relying on finding them after the fact.
Question 7: What is 'gold plating' in project quality management?
- Adding extra features beyond the agreed scope without authorization (Correct answer)
- Using expensive materials to improve product durability
- Applying Six Sigma methodologies to all deliverables
- Documenting quality results in a gold-standard format
Correct answer: Adding extra features beyond the agreed scope without authorization
Gold plating refers to adding unrequested features or enhancements beyond the approved scope, which should be avoided.
