CPP Quality Control & Process Improvement 3 — Questions and Answers
Question 1: A parking facility's gate arm has malfunctioned 8 times in 90 days. Which quality improvement tool would best prioritize repair actions based on frequency and impact?
- Scatter diagram
- Run chart
- Pareto analysis (Correct answer)
- Histogram
Correct answer: Pareto analysis
Pareto analysis applies the 80/20 rule to identify which failure types account for the majority of problems, enabling prioritized corrective action.
Question 2: When conducting a facility audit as part of continuous quality improvement, which document serves as the primary reference for evaluating compliance?
- Customer satisfaction surveys
- Standard operating procedures (SOPs) (Correct answer)
- Prior year financial statements
- Employee performance reviews
Correct answer: Standard operating procedures (SOPs)
Standard operating procedures define expected performance benchmarks against which actual operations are measured during an audit.
Question 3: In quality management, what is the key distinction between 'quality assurance' and 'quality control'?
- QA is reactive; QC is proactive
- QA focuses on preventing defects through process design; QC focuses on detecting defects in outputs (Correct answer)
- QA applies only to equipment; QC applies to staff
- QA is performed by managers; QC is performed by frontline staff
Correct answer: QA focuses on preventing defects through process design; QC focuses on detecting defects in outputs
Quality assurance is proactive and process-oriented, while quality control is reactive and focused on inspecting finished outputs for defects.
Question 4: A parking operation uses mystery shoppers to evaluate service quality. This practice is an example of which quality measurement approach?
- Internal benchmarking
- Third-party audit (Correct answer)
- Statistical process control
- Gap analysis
Correct answer: Third-party audit
Mystery shoppers are external evaluators who provide an unbiased third-party assessment of service quality from a customer's perspective.
Question 5: Which concept in process improvement refers to continuously making small, incremental improvements rather than large, one-time overhauls?
- Re-engineering
- Kaizen (Correct answer)
- Benchmarking
- Six Sigma
Correct answer: Kaizen
Kaizen is a Japanese philosophy of continuous, incremental improvement involving all employees in making small, ongoing enhancements to processes.
Question 6: A parking manager notices that revenue per space varies significantly between comparable garages. The BEST first step in a formal process improvement initiative is to:
- Immediately implement the highest-revenue garage's practices at all locations
- Define the problem scope and collect baseline performance data (Correct answer)
- Hire a consultant to redesign all revenue processes
- Purchase new technology for underperforming garages
Correct answer: Define the problem scope and collect baseline performance data
Defining the problem and establishing baseline data is the critical first step so that improvements can be measured against a known starting point.
Question 7: In a parking facility's quality improvement program, a 'control chart' showing data points consistently near the upper control limit would suggest:
- The process is stable and performing optimally
- A potential systematic issue requiring investigation before a violation occurs (Correct answer)
- Normal random variation within acceptable bounds
- The control limits need to be widened
Correct answer: A potential systematic issue requiring investigation before a violation occurs
Data consistently clustering near a control limit (even within bounds) indicates a non-random pattern signaling a potential process shift requiring investigation.
