OM TEST 3 EXAM QUESTIONS AND ANSWERS
Kanban means "symbol" or "box" in Japanese. - CORRECT ANSWER✅✅False
You have been called in as a consultant to set up a kanban control system. The first thing you do is to
determine the number of kanban card sets needed. Your research shows that the expected demand
during lead time for a particular component is 1,200 per hour. You estimate the safety stock should be
set at 5 percent of the demand during lead time. The tote trays used as containers can hold 2 units of
stock, and the lead time to replenish an order is 10 hours. Which of the following is the number of
kanban card sets necessary to support this situation? - CORRECT ANSWER✅✅6,300
k= 1,200 x 10 x 1.05/2= 6,300
When implementing a lean production system, a stabilized schedule is achieved using which of the
following? - CORRECT ANSWER✅✅Level scheduling
Lean production makes implementing green strategies in manufacturing processes more difficult. -
CORRECT ANSWER✅✅False
JIT manufacturing forces a firm to work with a lower water level despite safety hazards. - CORRECT
ANSWER✅✅False
In setting up a kanban control system you need to determine the number of kanban card sets needed. If
the expected demand during lead time is 25 per hour, the safety stock is 20 percent of the demand
during lead time, the container size is 5, and the lead time to replenish an order is 5 hours, what the
number of kanban card sets is needed? - CORRECT ANSWER✅✅30
k= 25 x 5 x 1.20/5= 30

Which of the following is not listed in the textbook as a component of a lean supply chain? - CORRECT
ANSWER✅✅Lean management
One of the many lean techniques that have been successfully applied in service firms is the eliminating
of unnecessary activities. - CORRECT ANSWER✅✅True
A kaizen burst is a symbol on a value stream map. - CORRECT ANSWER✅✅True
An activity where the parts that go into each unit of a product are periodically removed from inventory
and accounted for based on the number of units produced is called which of the following? - CORRECT
ANSWER✅✅Backflush
In the textbook, Toyota's Fujio Cho identified which of the following types of waste to be eliminated? -
CORRECT ANSWER✅✅Overproduction
Automation is a key to lean procurement. - CORRECT ANSWER✅✅True
The goal of JIT production is to drive all inventory queues lower. - CORRECT ANSWER✅✅False
, Applying lean concepts to logistics is difficult unless either the manufacturer or the customer owns the
logistics activities. - CORRECT ANSWER✅✅False
Group technology is a philosophy wherein similar parts are grouped together and the processes
required to make the parts are arranged as a work cell. - CORRECT ANSWER✅✅True
One of the many lean techniques that have been successfully applied in service firms is the upgrading of
quality. - CORRECT ANSWER✅✅True
Uniform planet loading is a process of smoothing the production activity flow to dampen the reaction
waves that normally occur in response to schedule variations. - CORRECT ANSWER✅✅True
Uniform planet loading is where you schedule production with different amounts of the same product
each day of the week to permit variation to meet changing demand requirements. - CORRECT
ANSWER✅✅False
Lean production is a management philosophy and a pull system throughout the plant. - CORRECT
ANSWER✅✅True
Which of the following address elimination of waste under lean production? - CORRECT
ANSWER✅✅Quality at the source
In setting up a Kanban control system you need to determine the number of Kanban card sets needed. If
assume the expected demand during lead time is 50 per hour, the safety stock is 20 percent of the
demand during lead time, the container size is 4, and the lead time to replenish an order is 8 hours,
what number of Kanban card sets is needed? - CORRECT ANSWER✅✅120
k= 50 x 8 x 1.20/4= 120
