B
Characteristics of just-in-time partnerships do NOT include: A. produce with zero defects. B. large lot sizes to save on setup costs and to gain quantity discounts. C. removal of in-transit inventory. D. focus on core competencies. E. long-term contracts.
B. large lot sizes to save on setup costs and to gain quantity discounts
which of the following is generally found in most Lean environments? A. push systems B. a push system for high margin items and a pull system for low margin items C. pull systems D. a push system for purchased parts and a pull system for manufactured parts E. a push or pull system, depending upon the rate of demand
C
The list of 5Ss, although it looks like a housekeeping directive, supports lean production by: A. eliminating wasted motion through ergonomic studies, in the "support" category. B. reducing inventory, in the "standardize" category. C. identifying non-value items and removing them, in the "sort/segregate" category. D. building good safety practices, in the "shine/sweep" category. E. increasing variability through standardized procedures, in the "standardize" category.
C. identifying non-value items and removing them, in the "sort/segregate" category.
Which one of the following is a concern expressed by suppliers in JIT partnerships? A. customers' infrequent engineering changes B. delivery to the point of use C. having too many customers D. having limited ability to respond to changes in product and quality E. large lot sizes
D. having limited ability to respond to changes in product and quality
what does TPS stand for? A. Total Process Simplification B. Transparent Processing System C. Total Production Streamlining D. Taguchi's Production S's E. Toyota Production System
E
Who is credited with coining the phrase, "Inventory is evil"? A. Taiichi Ohno B. Poka Yoke C. Kanban Polka D. Pat "Keiretsu" Morita E. Shigeo Shingo
E. Shigeo Shingo
A kanban system requires that the process has little variability in lead time because shortages impact the entire production system. T/F
T
which of the following is NOT one of the Seven Wastes? A. defective product B. assignment C. overproduction D. transportation E. motion
assignment
Which of the following is specifically characterized by a focus on continuous important, respect for people, and standard work practices? A. kanban B. Just-in-time (JIT) C. Toyota Production System (TPS) D. Lean operations E. Material requirements planning (MRP)
c
a push system means providing the next station with exactly what is needed when it is needed.
false
Which of the following is specifically characterized by elimination of waste through a focus on exactly what the customer wants? A. Toyota Production System (TPS) B. kanban C. Material requirements planning (MRP) D. Lean operations E. Just-in-time (JIT)
lean operations
Variability in manufacturing can occur because engineering drawings or specifications are incomplete or inaccurate.
true
the 5Ss-sort/segregate . simplify/straighten, shine/sweep, standardize, and sustain/self discipline - are important to lean production because they act as a means to reduce waste.
true
waste is anything that does not add value from the consumer's perspective
true
Which one of the following is not benefit of JIT implementation? A. rework reduction B. variability increase C. quality improvement D. cost reduction E. rapid throughput
variability increase
If the goals of JIT partnerships are met, which of the following is a result? A. In-transit inventory falls as suppliers are located closer to facilities. B. In-plant inventory replaces in-transit inventory. C. For incoming goods, receiving activity and inspection are outsourced. D. Suppliers maintain a variety of customers to reduce risk. E. All of the above are consequences of meeting the JIT partnership goals.
In-transit inventory falls as suppliers are located closer to facilities.
