CSPM CSPM Quality Management & Assurance 2 — Questions and Answers
Question 1: What is the key distinction between Quality Assurance (QA) and Quality Control (QC)?
- QA inspects final products; QC reviews processes
- QA focuses on process adherence to prevent defects; QC inspects outputs to detect defects (Correct answer)
- QA is performed by external auditors only; QC is internal
- QA and QC are identical activities
Correct answer: QA focuses on process adherence to prevent defects; QC inspects outputs to detect defects
QA is a proactive, process-focused activity aimed at preventing defects, while QC is a reactive, output-focused activity that detects and corrects defects.
Question 2: A senior project manager reviews a control chart and finds data points outside the control limits. What does this indicate?
- Normal process variation that requires no action
- Special cause variation indicating an out-of-control process that requires investigation (Correct answer)
- The project is ahead of schedule
- Budget forecasts need revision
Correct answer: Special cause variation indicating an out-of-control process that requires investigation
Data points outside control limits signal special cause variation — abnormal events that require root cause investigation and corrective action.
Question 3: Which quality improvement methodology uses a Define-Measure-Analyze-Improve-Control cycle to reduce defects?
- Agile Scrum
- Six Sigma DMAIC (Correct answer)
- PRINCE2
- Lean Kanban
Correct answer: Six Sigma DMAIC
Six Sigma's DMAIC framework provides a structured, data-driven approach to identifying defect sources and implementing sustainable quality improvements.
Question 4: A Pareto Chart is used in quality management primarily to:
- Track project schedule milestones
- Identify the vital few causes that account for the majority of quality problems (Correct answer)
- Document lessons learned
- Assign quality responsibilities to team members
Correct answer: Identify the vital few causes that account for the majority of quality problems
A Pareto Chart applies the 80/20 rule to identify the small number of causes responsible for most quality defects, enabling focused corrective action.
Question 5: During a quality audit on a large US infrastructure project, the auditor finds that the team is following outdated procedures. What is the BEST course of action?
- Continue with current procedures to avoid disruption
- Update the procedures, retrain the team, and document the change in the quality management plan (Correct answer)
- Dismiss the auditor's findings and submit a rebuttal
- Delay addressing the issue until project closure
Correct answer: Update the procedures, retrain the team, and document the change in the quality management plan
Immediately updating procedures, retraining staff, and documenting changes ensures compliance and prevents quality failures from propagating through remaining project phases.
Question 6: What does 'Cost of Quality' (COQ) encompass in project management?
- Only the cost of quality control inspections
- All costs associated with preventing defects, appraising quality, and addressing failures (internal and external) (Correct answer)
- The budget allocated to the QA team
- The cost of hiring a quality consultant
Correct answer: All costs associated with preventing defects, appraising quality, and addressing failures (internal and external)
COQ includes prevention costs, appraisal costs, and failure costs (both internal rework and external warranty/recall), providing a comprehensive view of quality's financial impact.
