Project Management Project Quality Management 3 — Questions and Answers
Question 1: What is a control chart primarily used for in project quality management?
- Ranking defects by frequency
- Determining if a process is stable and within acceptable limits (Correct answer)
- Mapping relationships between two variables
- Identifying the root cause of a single defect
Correct answer: Determining if a process is stable and within acceptable limits
Control charts monitor process performance over time to determine whether variation is within statistically acceptable limits.
Question 2: Which term describes the acceptable range of variation specified in quality requirements?
- Control limit
- Specification limit (Correct answer)
- Sigma level
- Tolerance threshold
Correct answer: Specification limit
Specification limits define the customer-required boundaries for acceptable product or process performance.
Question 3: In Six Sigma, what does 'DMAIC' stand for?
- Define, Measure, Analyze, Improve, Control (Correct answer)
- Design, Monitor, Audit, Implement, Close
- Define, Manage, Assess, Integrate, Control
- Determine, Measure, Analyze, Inspect, Complete
Correct answer: Define, Measure, Analyze, Improve, Control
DMAIC is the Six Sigma improvement cycle: Define, Measure, Analyze, Improve, Control.
Question 4: What is the purpose of a checklist in quality control?
- To rank team members by performance
- To ensure all required steps or items have been completed or verified (Correct answer)
- To calculate the cost of nonconformance
- To document lessons learned at project close
Correct answer: To ensure all required steps or items have been completed or verified
Checklists provide a structured way to verify that required steps have been performed and nothing is overlooked.
Question 5: Which process converts quality management plans and standards into executable quality activities?
- Plan Quality Management
- Control Quality
- Manage Quality (Correct answer)
- Monitor and Control Project Work
Correct answer: Manage Quality
Manage Quality (formerly Perform Quality Assurance) translates quality plans into specific activities to be performed during project execution.
Question 6: A run chart showing a series of seven consecutive data points all above the mean indicates what?
- Normal random variation
- A statistically significant trend or shift requiring investigation (Correct answer)
- The process is within control limits
- The sample size is too small
Correct answer: A statistically significant trend or shift requiring investigation
Seven consecutive points on one side of the mean (the Rule of Seven) signals a non-random pattern that may indicate a systemic problem.
Question 7: What distinguishes 'precision' from 'accuracy' in project quality?
- Precision means hitting the target; accuracy means consistent grouping
- Accuracy means hitting the target; precision means consistent grouping (Correct answer)
- Both terms are interchangeable in quality management
- Precision refers to cost; accuracy refers to schedule
Correct answer: Accuracy means hitting the target; precision means consistent grouping
Accuracy is closeness to the true value; precision is the consistency of repeated measurements regardless of whether they hit the target.
