PMP - Project Management Professional Project Quality Management Questions and Answers — Questions and Answers
Question 1: A project team is performing weekly code reviews and implementing a peer-programming policy to ensure the development process itself is effective at preventing defects. This is an example of which quality management process?
- Control Quality
- Plan Quality Management
- Manage Quality (Correct answer)
- Validate Scope
Correct answer: Manage Quality
Manage Quality is the process of translating the quality management plan into executable quality activities. It focuses on improving development processes to prevent defects. Control Quality, in contrast, focuses on inspecting the deliverables to identify defects.
Question 2: A project manager is facilitating a brainstorming session to investigate the root causes of a recurring product defect. The team organizes potential causes into categories such as people, process, tools, and environment. Which quality management tool is being used?
- Scatter Diagram
- Cause-and-effect Diagram (Correct answer)
- Control Chart
- Pareto Chart
Correct answer: Cause-and-effect Diagram
A cause-and-effect diagram, also known as an Ishikawa or fishbone diagram, is used to identify, sort, and display the potential causes of a specific problem. It helps trace a problem back to its root cause by organizing causes into categories.
Question 3: A project is experiencing significant warranty claims after product launch, which is damaging the company's reputation. These costs, associated with defects found by the customer, are classified under which category in the Cost of Quality (COQ) model?
- Prevention Costs
- Appraisal Costs
- Internal Failure Costs
- External Failure Costs (Correct answer)
Correct answer: External Failure Costs
External Failure Costs are costs incurred after the product has been delivered to the customer. This includes warranty work, returns, complaint handling, and loss of business reputation. These are part of the Cost of Non-conformance.
Question 4: A project manager wants to determine if the project's activities comply with the organization's documented quality policies and procedures. The goal is to identify ineffective processes and recommend improvements. What is the most appropriate activity to perform?
- A quality audit (Correct answer)
- A control quality inspection
- A risk review meeting
- A stakeholder engagement assessment
Correct answer: A quality audit
A quality audit is a structured, independent review to determine if project activities comply with organizational and project policies, processes, and procedures. Its main purpose is to identify inefficient and ineffective policies and improve processes.
Question 5: A manufacturing process produces bolts with diameters that are consistently measured within a very tight range of 10.01mm to 10.02mm. However, the customer specification requires a diameter of exactly 12.00mm. How would you describe the measurements of this process?
- Both accurate and precise
- Accurate, but not precise
- Precise, but not accurate (Correct answer)
- Neither accurate nor precise
Correct answer: Precise, but not accurate
Precision refers to the closeness of repeated measurements to each other (consistency). Accuracy refers to how close a measurement is to the true or specified value. The process is precise because the measurements are tightly clustered, but it is not accurate because they are far from the required 12.00mm specification.
Question 6: Which of the following is a key output of the Plan Quality Management process that describes a project or product attribute and how it will be measured by the Control Quality process?
- Quality Reports
- Verified Deliverables
- Quality Metrics (Correct answer)
- Change Requests
Correct answer: Quality Metrics
Quality Metrics are a direct output of the Plan Quality Management process. They describe a specific project or product attribute and define how the Control Quality process will measure it (e.g., defect density, on-time performance). Quality Reports are an output of Manage Quality, and Verified Deliverables are an output of Control Quality.
