1. What does 'Genchi Genbutsu' mean in the context of lean and the Toyota Way? → Go and see for yourself at the actual place
2. In production scheduling, 'finite scheduling' differs from 'infinite scheduling' in that finite scheduling: → Limits planned load to available capacity
3. What is the purpose of a 'kanban' system in lean manufacturing? → To signal replenishment of materials or production of items through visual triggers
4. Why is risk management an essential part of supply chain strategy? → To identify and minimize potential risks to supply chain operations.
5. How does demand variability affect supply chain strategy? → It makes demand forecasting difficult, requiring more flexible supply chain strategies.
6. How does demand management affect production scheduling? → It helps align production schedules with actual customer demand.
7. What is the importance of supply chain visibility? → It helps businesses respond quickly to changes and disruptions in the supply chain.
8. Why is demand forecasting critical in demand management? → It enables businesses to plan production and inventory more effectively.
9. How do reorder points impact inventory management in supply planning? → They trigger the automatic ordering of materials when stock levels are low.
10. What is the role of sales orders in demand management? → They provide real-time demand data, which updates forecasts and production plans.
11. The 'critical ratio' dispatching rule calculates priority as: → (Time remaining until due date) divided by (work remaining)
12. Why is collaboration with sales and marketing essential in demand management? → It helps to ensure demand forecasts reflect market trends and customer behavior.
13. What is the DMAIC framework primarily associated with? → Six Sigma process improvement
14. When a design constraint conflicts with a stakeholder preference in American Production and Inventory Control Society Certified, the BEST approach is to: → Evaluate both factors, communicate trade-offs, and find an optimal solution
15. What role does inventory management play in supply chain strategy? → It helps manage stock levels, reducing waste and improving cash flow.
16. In master scheduling, the 'demand time fence' is the period during which: → Only actual customer orders drive the schedule
17. Which scheduling approach assigns jobs to work centers based on the least amount of work remaining? → Least Work Remaining (LWR)
18. Rough-Cut Capacity Planning (RCCP) is primarily used to: → Validate the feasibility of the MPS against key resources
19. What is the main purpose of supply planning? → To ensure that the right materials and resources are available to meet demand.
20. How does supplier performance impact supply planning? → It ensures timely deliveries and smooth production schedules.
21. Which metric measures the percentage of time a machine is producing quality parts when it is scheduled to run? → Overall Equipment Effectiveness (OEE)
22. Overall Equipment Effectiveness (OEE) is calculated using which three factors? → Availability, Performance, and Quality
23. What is the MOST important leadership quality for a APICS certified professional managing a team? → Demonstrating integrity, clear communication, and ability to develop team members
24. What does the lean concept of 'Takt time' represent? → The rate at which products must be produced to meet customer demand
25. What role does safety stock play in supply planning? → To maintain inventory availability during demand fluctuations or supply chain disruptions.
26. Which technique is used to simulate the impact of a potential order on the master schedule without committing resources? → Capable-to-promise (CTP)
27. What is the MOST important leadership quality for a APICS certified professional managing a team? → Demonstrating integrity, clear communication, and ability to develop team members
28. Available-to-Promise (ATP) is calculated as: → Supply minus demand not yet promised to customers
29. In a push manufacturing system, production is triggered by: → A forecast or production schedule issued in advance
30. What is the PRIMARY purpose of obtaining APICS certification in American Production and Inventory Control Society Certified? → To demonstrate verified competency and adherence to professional standards
