CPIM Quality and Continuous Improvement 4 — Questions and Answers
Question 1: In Total Quality Management (TQM), what role do customers play in defining quality?
- Customers define quality through their satisfaction and requirements (Correct answer)
- Quality is defined solely by engineering specifications
- Regulatory agencies set quality standards, not customers
- Quality is defined by the lowest achievable cost
Correct answer: Customers define quality through their satisfaction and requirements
TQM holds that quality is defined by the customer — a product is only as good as it meets or exceeds customer needs and expectations.
Question 2: Which technique involves a cross-functional team tracing the flow of a product and information to identify waste and non-value-added steps?
- Value stream mapping (Correct answer)
- Process failure mode analysis
- Regression analysis
- Gantt charting
Correct answer: Value stream mapping
Value stream mapping (VSM) visually depicts current and future state flows to expose waste and target improvement opportunities.
Question 3: A company reduces its supplier base from 120 to 15 strategic partners. What quality benefit does this typically produce?
- Lower purchase prices due to competition among more suppliers
- Closer relationships enabling better quality collaboration and improvement (Correct answer)
- Increased redundancy to prevent supply disruptions
- Faster competitive bidding cycles
Correct answer: Closer relationships enabling better quality collaboration and improvement
Reducing suppliers to a strategic few allows deeper partnerships, shared quality systems, joint improvement initiatives, and clearer accountability.
Question 4: What is the primary objective of a corrective action system in quality management?
- To punish employees responsible for defects
- To identify, analyze, and eliminate the root cause of nonconformances so they do not recur (Correct answer)
- To document defects for warranty tracking purposes only
- To perform product recall notifications
Correct answer: To identify, analyze, and eliminate the root cause of nonconformances so they do not recur
A corrective action system drives permanent elimination of nonconformance root causes to prevent recurrence.
Question 5: Which of the following best describes 'benchmarking' as a quality improvement tool?
- Setting internal performance targets based on historical averages
- Comparing processes and performance metrics against best-in-class organizations to identify improvement gaps (Correct answer)
- Measuring machine capability against engineering tolerances
- Reviewing financial reports to set quality budgets
Correct answer: Comparing processes and performance metrics against best-in-class organizations to identify improvement gaps
Benchmarking compares an organization's processes and results with best practices from internal, competitive, or world-class external sources.
Question 6: In SPC, what does an 'out-of-control' signal on a control chart indicate?
- The process is producing defective products
- A special cause of variation has been detected and should be investigated (Correct answer)
- The control limits need to be recalculated
- The process capability index is below 1.0
Correct answer: A special cause of variation has been detected and should be investigated
An out-of-control signal means a special (assignable) cause of variation is present, which requires investigation and correction.
Question 7: Which approach to quality improvement focuses on incremental, continuous small improvements made by all employees rather than large breakthrough changes?
- Reengineering
- Kaizen (Correct answer)
- Six Sigma DMADV
- Hoshin Kanri
Correct answer: Kaizen
Kaizen is the Japanese philosophy of continuous improvement through small, ongoing, incremental changes involving everyone.
