PMBOK Project Quality Management 1 — Questions and Answers
Question 1: What is the primary purpose of the Plan Quality Management process in PMBOK?
- To inspect deliverables for defects after completion
- To identify quality requirements and standards for the project (Correct answer)
- To approve the project management plan baseline
- To measure project performance against cost baselines
Correct answer: To identify quality requirements and standards for the project
Plan Quality Management identifies quality requirements and standards relevant to the project and documents how compliance will be demonstrated.
Question 2: Which of the following best describes 'Cost of Quality' (COQ) in PMBOK?
- The total budget allocated for quality assurance activities
- The cost of hiring quality inspectors on the project
- The costs of conformance and nonconformance to quality requirements (Correct answer)
- The price charged for quality management software tools
Correct answer: The costs of conformance and nonconformance to quality requirements
Cost of Quality includes costs of conformance (prevention and appraisal) and costs of nonconformance (internal and external failure costs).
Question 3: In PMBOK, which quality management process involves auditing quality requirements and results to ensure appropriate standards are being used?
- Plan Quality Management
- Control Quality
- Manage Quality (Correct answer)
- Monitor and Control Project Work
Correct answer: Manage Quality
Manage Quality (formerly Quality Assurance) involves auditing quality requirements and results to ensure the project employs appropriate quality standards and operational definitions.
Question 4: A control chart is primarily used to determine which of the following?
- The root cause of quality defects in a product
- The relationship between two quality variables
- Whether a process is operating within acceptable limits (Correct answer)
- The frequency of different types of defects ranked by occurrence
Correct answer: Whether a process is operating within acceptable limits
Control charts monitor whether a process is stable or has predictable performance, showing when a process goes outside acceptable control limits.
Question 5: What distinguishes prevention costs from appraisal costs in quality management?
- Prevention costs are incurred during testing; appraisal costs during design
- Prevention costs keep defects from occurring; appraisal costs find defects after they occur (Correct answer)
- Prevention costs are fixed; appraisal costs are variable by project phase
- Prevention costs relate to training only; appraisal costs relate to rework only
Correct answer: Prevention costs keep defects from occurring; appraisal costs find defects after they occur
Prevention costs are invested to stop defects from occurring, while appraisal costs are incurred to assess whether quality requirements have been met.
Question 6: What is 'gold plating' in the context of project quality management?
- Adding extra features or functionality beyond the agreed project scope (Correct answer)
- Applying premium quality materials to project deliverables
- Exceeding quality standards set in the quality management plan
- Using expensive quality assurance tools not in the budget
Correct answer: Adding extra features or functionality beyond the agreed project scope
Gold plating refers to adding extra features or exceeding requirements beyond what was requested, which wastes resources and may introduce unplanned risk.
Question 7: Which quality management tool ranks defect categories by frequency to help prioritize improvement efforts?
- Control chart
- Scatter diagram
- Pareto diagram (Correct answer)
- Run chart
Correct answer: Pareto diagram
A Pareto diagram is a histogram that ranks defect categories by frequency, helping teams focus on the vital few causes responsible for the most problems.
