Project Risk Management Quality Control & Assurance 5 — Questions and Answers
Question 1: A project team is using the 'five whys' technique during a quality review. What is the PRIMARY goal of this technique?
- To document five examples of the defect for the lessons learned register
- To iteratively ask 'why' to drill down to the fundamental root cause of a problem (Correct answer)
- To identify five potential solutions for a quality deviation
- To assign accountability for a quality failure across five team members
Correct answer: To iteratively ask 'why' to drill down to the fundamental root cause of a problem
The five whys technique iteratively asks 'why' at each level of an answer until the root cause is identified, typically requiring about five iterations.
Question 2: Which statement BEST describes the relationship between quality and grade in project management?
- High quality and high grade are always achieved together
- A product can be high quality but low grade, or low quality but high grade (Correct answer)
- Grade refers to the level of quality achieved on the project
- Low-grade products are always considered low quality
Correct answer: A product can be high quality but low grade, or low quality but high grade
Quality is the degree to which requirements are met; grade is a ranking of features — a low-grade product meeting all its specifications is high quality, while a high-grade product with defects is low quality.
Question 3: A project manager discovers that a subcontractor's deliverable passed quality inspection but later failed in the integrated system. Which quality process was most likely inadequate?
- Individual unit testing of the deliverable components
- Integration testing as part of the quality control plan (Correct answer)
- The subcontractor's internal quality assurance processes
- The frequency of quality audits during the project
Correct answer: Integration testing as part of the quality control plan
When a component passes unit inspection but fails in integration, the quality control plan likely lacked sufficient integration testing to verify compatibility within the larger system.
Question 4: What is the significance of the 'voice of the customer' (VOC) in quality planning?
- It defines the legal requirements the project must comply with
- It captures customer needs and expectations to translate into measurable quality requirements (Correct answer)
- It replaces the need for formal quality standards and benchmarks
- It is used exclusively during the project closure phase for satisfaction surveys
Correct answer: It captures customer needs and expectations to translate into measurable quality requirements
VOC translates qualitative customer needs and expectations into specific, measurable quality requirements that guide planning and help prevent requirement misalignment.
Question 5: During project execution, the team identifies a quality risk that could affect final deliverable acceptance. Where should this risk be documented?
- The quality management plan only
- The project charter as a constraint
- The risk register with appropriate risk response strategies (Correct answer)
- The lessons learned register for future projects
Correct answer: The risk register with appropriate risk response strategies
Quality risks that could affect project outcomes should be documented in the risk register with probability, impact, and planned response strategies for active management.
Question 6: A histogram of defect data shows a bimodal distribution (two distinct peaks). What does this most likely indicate?
- The process is operating normally with expected variation
- Two different processes or conditions may be contributing to the defects (Correct answer)
- The sample size was too small and the data is unreliable
- The process has reached Six Sigma performance levels
Correct answer: Two different processes or conditions may be contributing to the defects
A bimodal distribution suggests two separate subpopulations or process conditions (e.g., two shifts, two machines) are producing different defect patterns that need separate analysis.
Question 7: A project quality plan specifies that all deliverables must be peer-reviewed before submission. A team member skips the peer review due to schedule pressure and the deliverable fails acceptance. What is the PRIMARY lesson for the project manager?
- Schedule more peer reviews to compensate for the missed one
- Process adherence must be enforced even under schedule pressure to prevent costly rework (Correct answer)
- The peer review requirement should be removed to prevent future schedule conflicts
- Accept that schedule pressure occasionally justifies bypassing quality steps
Correct answer: Process adherence must be enforced even under schedule pressure to prevent costly rework
Bypassing quality processes under schedule pressure typically creates greater schedule and cost impacts downstream through rework, demonstrating that quality shortcuts are false economies.
