It is important to lower the water (inventory) completely to expose all the rocks (problems). True False?

35. Increased setup times equal increased work in process inventories.
True False
TRUE
With higher setup times, batch quantities and work-in-process inventory increases.
36. Kanban focuses on specific part numbers; CONWIP does not.
True False
TRUE
This makes CONWIP more suitable for a mixed-product environment.
37. Lean systems typically require that suppliers be able to provide large lots at periodic intervals.
True False
FALSE
Lean systems need suppliers making frequent deliveries of small lots.
38. Lean purchasing requires frequent contract bidding by multiple sources to ensure the buyer of competitive prices.
True False
FALSE
Lean purchasing requires collaborative relationships with a relatively small number of suppliers.
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
FALSE
Lean operations limit contact to only a first tier of suppliers. These are then responsible for sourcing at the second tier and beyond.
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
TRUE
Kanban can be implemented quite well without computers.
41. A benefit of the lean philosophy is the flexibility to respond quickly to changing customer requirements.
True False
TRUE
Lean systems can be more responsive to changing customer requirements.
42. A benefit of lean systems is that lead times are increased allowing more time for processing.
True False
FALSE
Lead times are reduced in lean systems.
43. A successful conversion to a lean system requires that every vendor use lean approaches prior to the organization’s implementation.
True False
FALSE
Successful conversion to a lean system tends to require a more cooperative relationship with vendors.
44. The single-minute exchange of die is a system for reducing defective product.
True False
FALSE
Single-minute exchange of die reduces setup costs and therefore lot sizes.
45. In a balanced system, cycle time is equal to Takt time.
True False
TRUE
Takt time is equal to cycle time in a balanced system.
46. It is important to lower the water (inventory) completely to expose all the rocks (problems).
True False
FALSE
Inventory only needs to be lowered modestly to expose the most pressing problems. Over time, with subsequent reductions, all problems will be uncovered.
