CPT Quality Assurance & Improvement 3 — Questions and Answers
Question 1: A CPT practitioner discovers that a high defect rate is caused by unclear work instructions rather than inadequate skill. This finding is best categorized as a:
- Knowledge/skill gap
- Environmental/workplace factor (Correct answer)
- Motivational barrier
- Selection and placement issue
Correct answer: Environmental/workplace factor
Unclear work instructions represent an environmental or workplace factor — a condition in the work environment that prevents performance regardless of worker ability.
Question 2: Which principle of Total Quality Management (TQM) emphasizes that preventing defects is less costly than detecting and correcting them after the fact?
- Customer focus
- Continuous improvement
- Quality at the source (Correct answer)
- Data-driven decision making
Correct answer: Quality at the source
Quality at the source (or defect prevention) holds that building quality into the process is always cheaper than inspecting for and fixing defects downstream.
Question 3: A performance technologist calculates an ROI of 120% for a lean process improvement initiative. What does this figure indicate?
- The initiative returned $1.20 for every $1 invested above break-even (Correct answer)
- The initiative's costs exceeded its benefits by 20%
- The program met 120% of its learning objectives
- Participants rated the program 120 out of 100 on satisfaction
Correct answer: The initiative returned $1.20 for every $1 invested above break-even
An ROI of 120% means the net benefits exceeded the total costs by 120%, or $1.20 in net benefit was returned for every dollar spent.
Question 4: Which process improvement methodology uses value stream mapping to identify and eliminate non-value-added steps?
- Six Sigma DMAIC
- Lean (Correct answer)
- ISO 9000
- Balanced Scorecard
Correct answer: Lean
Lean methodology uses value stream mapping to visualize workflows and systematically remove waste (muda) that does not add customer value.
Question 5: A quality review team uses a control chart and notices that several consecutive data points fall on the same side of the mean without exceeding control limits. This pattern is called a:
- Random variation
- Run or trend (Correct answer)
- Special-cause variation
- Specification breach
Correct answer: Run or trend
A run of consecutive points on one side of the centerline is a non-random pattern called a run or trend, signaling a potential process shift.
Question 6: When benchmarking a quality improvement process, what is the primary reason for comparing against best-in-class external organizations rather than only internal standards?
- External comparisons are cheaper to conduct
- Internal benchmarks always overstate performance gaps
- External benchmarks reveal performance levels that may redefine what is achievable (Correct answer)
- Regulatory bodies require external benchmarking
Correct answer: External benchmarks reveal performance levels that may redefine what is achievable
External benchmarking exposes an organization to higher performance ceilings it may not have considered, enabling breakthrough rather than incremental improvement.
Question 7: A CPT practitioner is asked to assess whether an improvement initiative achieved its intended outcomes AND whether those outcomes still align with current organizational goals. This is called:
- Confirmative evaluation (Correct answer)
- Formative evaluation
- Needs assessment
- Cost-benefit analysis
Correct answer: Confirmative evaluation
Confirmative evaluation examines whether an intervention continues to produce desired results and whether those results remain relevant over time.
