A functioning MRP system is required prior to adopting lean planning and control systems. True False 3. In a lean environment, anything not essential to the product or process is viewed as waste. True False 4. The ultimate goal of lean operations is a system characterized by the smooth, rapid flow of materials. True False 5. Although inventories are maintained, the goal of lean operations is to minimize safety stock. True False 6. Lean operations are unable to easily handle changes of output or product mix. True False 7. In the lean philosophy, producing more than two order quantities represents waste. True False 8. The four building blocks of lean operations are: product design, process design, personnel/organizational elements, and manufacturing planning and control. True False 9. Fast and simple are two common threads that run through the four building blocks of lean operations. True False 10. Valuestream mapping is a technique focused on finding new ways of adding value for critical stakeholders such as customers. True False 11. If a firm's product mix is 60% of product A and 20% each of products B and C, an optimal mixmodel production schedule would be successive sequences of AAABC. True False 12. Quality and highly capable production systems are requirements for the successful implementation of lean operations. True False 13. The small lotsizing policy works well in a situation where both holding costs and setup costs are high. True False 14. The use of small lot sizes in lean operations is in conflict with the EOQ approach since setup costs tend to be significantly higher than holding costs. True False 15. A basic requirement for operating with low inventories in lean systems is that major system problems must already have been solved and new problems will be solved as they appear. True False 16. A benefit of small lot sizes in lean systems is that each product is produced less frequently. True False 17. In the lean philosophy, the larger the lot size, the easier it is to schedule. True False 18. Setup time and its associated cost can often be reduced by the use of group technology. True False 19. Lean systems often use layouts that are based on group technology product requirements. True False 20. The goal of lean operations is to produce output using fewer resources than traditional planning systems. True False 21. "Autonomation" indicates that the firm is attempting to reduce its dependence on automated equipment. True False 22. "Preventive maintenance" is additional maintenance done immediately after a breakdown has occurred to help prevent any further breakdowns. True False 23. In the lean approach, inventories are reduced gradually, instead of eliminating inventories as rapidly as possible. True False 24. One problem with lean operations is that they can lead to much frustration and disappointment of people on the shop floor due to the need for continuously monitoring and expediting resource availability. True False 25. A real advantage of the lean philosophy is the reduction of coordination effort required. True False 26. The lean philosophy recognizes that some workinprocess inventories are a necessary investment to allow for smooth workflow. True False 27. Preventive maintenance will eliminate the need to carry supplies of spare parts. True False 28. A fundamental tenet of the lean philosophy is that workers are paid based on seniority. True False 29. In lean operations, a responsibility of the crosstrained worker is to check the quality of the work of others. True False 30. In lean operations, when work is completed at one work center, it is important to immediately move the completed work to the next work center to minimize idle time. True False 31. In a "pull system," a quantity of inventory in front of a workstation indicates problems at that workstation. True False 32. Limited WIP lowers inventory carrying costs but reduces flexibility. True False 33. Engineering changes can be very disruptive to smooth operations and should not be made in the six month period following introduction of a new product. True False 34. Kanban is the Japanese term for autonomation. True False 35. Increased setup times equal increased work in process inventories. True False 36. Kanban focuses on specific part numbers; CONWIP does not. True False 37. Lean systems typically require that suppliers be able to provide large lots at periodic intervals. True False 38. Lean purchasing requires frequent contract bidding by multiple sources to ensure the buyer of competitive prices. True False 39. One way of reducing the number of suppliers to the organization is to limit contacts to only one or two tiers of suppliers. True False 40. One major difference between the use of kanban and MRP II in scheduling the products to be built is that kanban is primarily a manual system while MRP II uses computers. True False 41. A benefit of the lean philosophy is the flexibility to respond quickly to changing customer requirements. True False 42. A benefit of lean systems is that lead times are increased allowing more time for processing. True False 43. A successful conversion to a lean system requires that every vendor use lean approaches prior to the organization's implementation. True False 44.

It is important to lower the water (inventory) completely to expose all the rocks (problems). True False 47. Successful lean implementation requires much more than slogans and idealistic goals such as zero inventories and zero defects. True False 48. Lean concepts include large lots to take advantage of the economies of scale. True False 49. Valuestream mapping is concerned strictly with the flow of materials through a production system.
