TRUE or FALSE
In lean operations, input resources arrive for processing only after the preceding batch
has been completed. - Answer TRUE
When the preceding batch has been completed, the workstation authorizes new input
resources to arrive.
TRUE or FALSE
A functioning MRP system is required prior to adopting lean planning and control
systems. - Answer FALSE
Lean planning and control can be implemented without the use of MRP.
TRUE or FALSE
In a lean environment, anything not essential to the product or process is viewed as
waste. - Answer TRUE
Eliminating such waste is central to the lean philosophy.
TRUE or FALSE
The ultimate goal of lean operations is a system characterized by the smooth, rapid flow
of materials. - Answer TRUE
A smooth, rapid material flow is the ideal in a lean environment.
TRUE or FALSE
Although inventories are maintained, the goal of lean operations is to minimize safety
stock. - Answer FALSE
The goal of lean operations is to eliminate safety stock.
TRUE or FALSE
Lean operations are unable to easily handle changes of output or product mix. - Answer
FALSE
Volume or product mix changes can easily undermine a system being operated
according to lean principles.
TRUE or FALSE

In the lean philosophy, producing more than two order quantities represents waste. -
Answer FALSE
Producing one order quantity in advance of demand represents waste.
TRUE or FALSE
The four building blocks of lean operations are: product design, process design,
personnel/organizational elements, and manufacturing planning and control. - Answer
TRUE
These are the building blocks of lean operations.
TRUE or FALSE
Fast and simple are two common threads that run through the four building blocks of
lean operations. - Answer TRUE
Streamlined and error-proof are lean ideals.
TRUE or FALSE
Value-stream mapping is a technique focused on finding new ways of adding value for
critical stakeholders such as customers. - Answer FALSE
Value-stream mapping is a visual tool used to systematically examine the flow of
materials and information.
TRUE or FALSE
If a firm's product mix is 60% of product A and 20% each of products B and C, an
optimal mix-model production schedule would be successive sequences of AAABC. -
Answer FALSE
An optimal schedule would be successive sequences of ABACA.
TRUE or FALSE
Quality and highly capable production systems are requirements for the successful
implementation of lean operations. - Answer TRUE
These help prevent waste.
TRUE or FALSE
, Chapter 14 MGMT 3180
The small lot-sizing policy works well in a situation where both holding costs and setup
costs are high. - Answer FALSE
Small lot-sizing is only workable when setup costs are low.
TRUE or FALSE
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. - Answer FALSE
These are not in conflict, since with low setup costs the EOQ leads to small lot sizes.
TRUE or FALSE
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. - Answer TRUE
Unless these problems are solved, steps required to work with low inventories are
economically infeasible.
TRUE or FALSE
A benefit of small lot sizes in lean systems is that each product is produced less
frequently. - Answer FALSE
Product versions are produced more frequently in lean systems.
TRUE or FALSE
In the lean philosophy, the larger the lot size, the easier it is to schedule. - Answer
FALSE
In the lean system, items with large lot sizes tend to be scheduled less frequently.
TRUE or FALSE
Setup time and its associated cost can often be reduced by the use of group
technology. - Answer TRUE
Group technology can help with reducing setup time and its associated cost.
TRUE or FALSE
Lean systems often use layouts that are based on group technology product
requirements. - Answer TRUE
