1. In 5S, what is the correct action taken with items tagged during the 'Sort' step that are deemed unnecessary? → Move tagged items to a red-tag area for evaluation and disposition decision
2. What lean tool is used to map all value-adding and non-value-adding steps across the entire supply chain from supplier to customer? → Extended value stream map
3. Which lean supply chain metric measures the time from raw material receipt to finished goods delivery to the customer? → Supply chain lead time
4. Which of the following is a benefit of Value Stream Mapping? → Process visualization and waste identification
5. How does shadow boarding (shadow boards) support the 5S 'Set in Order' step? → It uses silhouette outlines so missing or misplaced tools are immediately obvious
6. What is the purpose of a supplier scorecard in lean procurement? → To track and communicate supplier performance on quality, delivery, and cost metrics
7. What is a 'bottleneck' in process improvement? → A constraint slowing down workflow
8. What metric is most directly used to measure the success of a Kaizen event focused on cycle time reduction? → Before-and-after cycle time comparison
9. Which lean concept supports receiving deliveries directly to the point of use, bypassing central receiving and storage? → Direct-to-line delivery
10. In CLL practice, what is a needs assessment? → A systematic process to identify gaps between current conditions and desired outcomes
11. Why is communication essential in change management? → To align teams and reduce resistance
12. Which metric evaluates production speed? → Cycle time
13. Which of the following is NOT one of the 8 wastes in Lean? → Customer service
14. In CLL practice, what is a needs assessment? → A systematic process to identify gaps between current conditions and desired outcomes
15. Which of the following best describes 'continuous flow' as it relates to Kaizen improvement events? → Processing one piece at a time through sequential steps without queuing between steps
16. What is a critical element of successful change management? → Involving stakeholders and maintaining communication
17. Which approach is used in Lean for process improvement? → Kaizen
18. In CLL practice, what is a needs assessment? → A systematic process to identify gaps between current conditions and desired outcomes
19. In CLL practice, what is a conflict of interest? → A situation where personal interests could compromise professional judgment or objectivity
20. What tool is commonly used to identify waste in a process? → Value Stream Mapping
21. What is 'breakthrough Kaizen' (also known as Kaikaku) distinct from everyday Kaizen? → It involves radical, large-scale change rather than incremental improvement
22. Which of the following is a key type of waste in Lean? → Overproduction
23. What is the consequence of non-compliance in CLL professional practice? → Potential fines, license revocation, legal liability, and reputational damage
24. What does professional liability insurance protect a CLL practitioner against? → Financial loss from claims of negligence, errors, or omissions in professional services
25. What role does a Kaizen facilitator primarily serve during an improvement event? → Guide the team through the structured process while keeping them focused on the goal
26. Which lean improvement event is typically used to rapidly redesign a procurement or supply chain process with cross-functional teams? → Kaizen event (rapid improvement event)
27. In CLL practice, what is the purpose of regulatory compliance? → To ensure adherence to laws, regulations, and standards that govern professional practice
28. Which leadership style is most effective during Lean transformations? → Transformational
29. What is the goal of standard work in Lean? → To maintain consistency and support improvement
30. How does milk-run logistics support lean supply chain operations? → It makes frequent, small-lot pickups from multiple suppliers on a fixed route
