Project Planning and Monitoring Project Planning and Monitoring Quality Assurance & Control 1 — Questions and Answers
Question 1: What is the primary purpose of a quality management plan in a project?
- To define how quality will be managed and verified throughout the project (Correct answer)
- To list all defects found during testing
- To assign blame when quality issues arise
- To replace the project scope statement
Correct answer: To define how quality will be managed and verified throughout the project
A quality management plan defines the quality standards, processes, and responsibilities to ensure project deliverables meet requirements.
Question 2: What distinguishes quality assurance (QA) from quality control (QC)?
- QA focuses on process improvement while QC focuses on inspecting deliverables for defects (Correct answer)
- QA inspects products while QC audits processes
- QA is performed only at project end while QC happens continuously
- QA is done by customers and QC by the project team
Correct answer: QA focuses on process improvement while QC focuses on inspecting deliverables for defects
QA is a proactive process-oriented approach to prevent defects, while QC is a reactive inspection-oriented approach to identify defects in outputs.
Question 3: Which tool is commonly used in quality control to identify the most frequent causes of defects?
- Pareto chart (Correct answer)
- Scatter diagram
- Control chart
- Flowchart
Correct answer: Pareto chart
A Pareto chart ranks defect causes by frequency to help teams focus on the vital few causes responsible for most problems (the 80/20 rule).
Question 4: What does a control chart primarily help a project manager determine?
- Whether a process is stable and within acceptable variation limits (Correct answer)
- Which team member caused the most defects
- The total cost of quality for the project
- Whether the project is on schedule
Correct answer: Whether a process is stable and within acceptable variation limits
Control charts display process performance over time and show whether variation is within control limits, indicating process stability.
Question 5: What is the 'cost of quality' concept in project management?
- The total cost of conformance work plus nonconformance work throughout the project (Correct answer)
- Only the cost of fixing defects after delivery
- The budget allocated exclusively to the QA team
- The price charged to customers for quality guarantees
Correct answer: The total cost of conformance work plus nonconformance work throughout the project
Cost of quality includes both prevention and appraisal costs (conformance) and internal/external failure costs (nonconformance).
Question 6: During a quality audit, what is the auditor's main objective?
- To identify whether project processes comply with organizational and project quality policies (Correct answer)
- To punish team members who violated quality standards
- To rewrite the project's quality management plan
- To approve the final project deliverable for customer acceptance
Correct answer: To identify whether project processes comply with organizational and project quality policies
A quality audit independently assesses whether project activities comply with established policies, processes, and procedures to identify improvements.
