CAPM CAPM Quality Management & Control 1 — Questions and Answers
Question 1: According to the PMBOK Guide, which quality management process involves auditing quality requirements and results from quality control measurements to ensure appropriate quality standards are used?
- Plan Quality Management
- Manage Quality (Correct answer)
- Control Quality
- Perform Quality Assurance
Correct answer: Manage Quality
Manage Quality (formerly Perform Quality Assurance) is the process of auditing quality requirements and results to ensure appropriate standards and operational definitions are applied.
Question 2: What is a fishbone (Ishikawa) diagram primarily used for in project quality management?
- Tracking defect trends over time
- Identifying root causes of quality problems (Correct answer)
- Displaying the frequency of defects
- Mapping the sequence of quality checks
Correct answer: Identifying root causes of quality problems
A fishbone or Ishikawa diagram is a cause-and-effect diagram used to identify the root causes contributing to a quality problem.
Question 3: Which concept states that the cost of preventing defects is less than the cost of correcting them after they occur?
- Gold plating
- Cost of quality (Correct answer)
- Marginal analysis
- Quality audit
Correct answer: Cost of quality
Cost of quality (COQ) encompasses prevention costs, appraisal costs, and failure costs, and the principle holds that prevention is cheaper than correction.
Question 4: In Control Quality, a control chart's upper and lower control limits are typically set at how many standard deviations from the mean?
- 1
- 2
- 3 (Correct answer)
- 6
Correct answer: 3
Control chart control limits are set at ±3 standard deviations (3 sigma) from the process mean to distinguish normal variation from special cause variation.
Question 5: What is 'gold plating' in the context of project quality management?
- Delivering exactly what the customer asked for
- Adding extra features beyond the agreed scope (Correct answer)
- Using premium materials to meet specifications
- Applying Six Sigma methods to quality control
Correct answer: Adding extra features beyond the agreed scope
Gold plating refers to adding features or enhancements beyond the agreed-upon scope, which is discouraged because it consumes resources without approved value.
Question 6: A Pareto chart helps a project manager prioritize quality issues by displaying which information?
- Process variation over time
- Defect categories ranked by frequency or impact (Correct answer)
- Correlation between two quality variables
- The sequence of quality control steps
Correct answer: Defect categories ranked by frequency or impact
A Pareto chart ranks defect categories from most to least frequent, helping teams focus on the 20% of causes responsible for 80% of defects.
