Project Planning and Monitoring Quality Assurance & Performance Metrics 1 — Questions and Answers
Question 1: What is the difference between quality assurance (QA) and quality control (QC) in project management?
- QA audits processes; QC inspects deliverables for defects (Correct answer)
- QA tests deliverables; QC defines quality standards
- QA is done at project close; QC is ongoing
- QA and QC are interchangeable terms
Correct answer: QA audits processes; QC inspects deliverables for defects
QA focuses on evaluating whether processes are being followed correctly, while QC focuses on verifying that outputs meet quality standards.
Question 2: Which chart is most useful for identifying the most frequent causes of defects in a project?
- Pareto chart (Correct answer)
- Control chart
- Scatter diagram
- Run chart
Correct answer: Pareto chart
A Pareto chart ranks causes by frequency, highlighting the vital few issues responsible for the majority of defects.
Question 3: What does a Key Performance Indicator (KPI) measure in project monitoring?
- Progress toward a specific project objective (Correct answer)
- The number of team members assigned
- Total project budget consumed
- Stakeholder satisfaction scores only
Correct answer: Progress toward a specific project objective
KPIs are quantifiable metrics that indicate whether a project is on track to achieve its defined objectives and success criteria.
Question 4: What is the purpose of a control chart in quality monitoring?
- To determine if a process is in statistical control by tracking variation over time (Correct answer)
- To assign defect resolution tasks to team members
- To display project milestones on a timeline
- To calculate earned value metrics
Correct answer: To determine if a process is in statistical control by tracking variation over time
A control chart uses upper and lower control limits to distinguish normal process variation from special-cause variation requiring investigation.
Question 5: Which quality management approach emphasizes preventing defects rather than detecting them after the fact?
- Prevention over inspection (Correct answer)
- Acceptance sampling
- Gold plating
- Retrospective review
Correct answer: Prevention over inspection
Prevention over inspection is a core quality principle that reduces rework costs by building quality into the process from the start.
Question 6: What is a quality audit in project management?
- A structured review to determine whether project activities comply with quality policies and standards (Correct answer)
- A financial review of project expenditures
- A performance review of individual team members
- An end-of-project lessons learned session
Correct answer: A structured review to determine whether project activities comply with quality policies and standards
A quality audit independently assesses whether the project's quality processes are being followed and identifies improvements.
