Supply Chain Chapter 16
Which of the following is NOT one of the Seven Wastes?
Assignment
Concerning relationships with suppliers, which of the following combinations is critical to the success of JIT?
Close relationships with trust
In JIT partnerships, suppliers have several concerns. Which of the following is NOT such a concern?
Costumers' infrequent engineering changes
Which of the following is NOT a source of variability
Employees, machines, and suppliers produce units that conform to standards
In a JIT system, production inspection adds value by identifying defective items
FALSE
Increasing inventory exposes variability in production processes
FALSE
JIT brings about competitive advantage by faster response to the customer regardless of cost
FALSE
JIT systems carry inventory just in case something goes wrong
FALSE
Level scheduling means producing at a constant rate, regardless of customer demands
FALSE
The number of kanbans decreases as safety stock is increased
FALSE
The quality management tool called poka-yoke is not relevant to JIT systems
FALSE
A push system means providing the next station with exactly what is needed when it is needed
FALSE - pull system
Customer demand will always remain an unknown, so it is not considered a source of variability
FASLE
If the goals of JIT partnerships are meant, which of the following is a result?
In-transit inventory falls as suppliers are located closer to facilities
Which of the following is not a goal of JIT partnerships?
Inspect all incoming shipments to ensure zero defects
Which of the following is specifically characterized by continuous and forced problem solving via a focus on throughput and reduced inventory?
JIT
Which of the following is specifically characterized by the elimination of waste through exactly what the customer wants?
Lean operations
Which of the following statements regarding a pull system is TRUE?
Problems become more obvious
A ---- is a concept that results in material being produced only when requested and moved to where it is needed just as it is needed
Pull system
If a factory wants to cut its current lot size in half, but what proportion must setup cost change?
Setup cost must be cut to one fourth its current value
Which of the following is specifically characterized by a focus on continuous improvement, respect for people, and standard work practices?
TPS
A common JIT layout tactic is to minimize distance
TRUE
A kanban system requires that the process has little variability in lead time because shortages impact the entire production system
TRUE
A scheduler may find that freezing the portion of the schedule closest to the due dates allows the production system to function and the schedule to be met
TRUE
Cross-training is a common JIT layout tactics to improve flexibility
TRUE
Hidden problems are generally uncovered during the process of reducing inventory
TRUE
JIT suppliers have concerns that the JIT firm's demands for small lot sizes are simply a way of transferring holding cost from the JIT firm to suppliers
TRUE
Many suppliers feel that having a variety of customers is better than being tied to long-term contracts with one customer
TRUE
One goal of JIT partnerships is the removal of in-plant inventory by delivery in small lots directly to the using department as needed
TRUE
Product storage is an example of waste in the sense that no value is added
TRUE
TPS stands for Toyota Production System
TRUE
The 5Ss - sort, simplify, shine, standardize, sustain - are important to lean production because they act as a means to reduce waste
TRUE
The first step in reducing setup times is the separation of setup into preparation activities and actual setup, so that as much work as possible can be done while machine or process is operating
TRUE
Variability in manufacturing can occur because engineering drawing or specifications are incomplete or inaccurate
TRUE
Waste is anything that does not add value from the consumer's perspective
TRUE
When implemented as a comprehensive operations strategy, JIT, TPS, and lean systems sustain competitive advantage and result in increased overall returns
TRUE
Which of the following is TRUE regarding the steps to reducing setup times?
The first step involves performing as much setup preparation as possible while the process/machine is operating The cycle of steps is repeated until setup time is reduced to under a minute The standardization of both tooling and work procedures is advantageous to setup Move material closer and improve material handling are done before operator training
---- is any deviation from the optimum process that delivers perfect product on time, every time
Variability
JIT makes demands on layers, including the need for:
distance reduction, increased flexibility, reduced space and inventory, cross-trained, flexible employees
Which one of the following is NOT a layout tactic in a JIT environment?
fixed equipment
The 5Ss:
have the "flavor" of a housekeeping list are a checklist for lean operations have become a list of seven items in American practice can be used to assist with necessary change in organizational culture
Which of the following is a concern expressed by suppliers in JIT partnerships
having limited ability to respond to changes in product and quality
The list of 5Ss, although it looks like a housekeeping directive, supports lean production by:
identifying non-value items and removing them in the "sort/segregate" category
Which of the following statements is TRUE regarding JIT inventory?
it is the minimum inventory necessary to keep a perfect system running
Characteristics of JIT partnerships do NOT include:
large lot sizes to save on setup costs and to gain quantity discounts
Which os the following is generally found in most lean environment
pull systems
Which one of the following is a characteristic of a JIT partnership?
removal of incoming inspection
How can a reduction of in-transit inventory be encouraged
supplier location near plants
Manufacturing cycle time is best defined as the:
time from raw materials receipt to finished product exit
Which one of the following is not a benefit of JIT implementation?
variability increase
