Card Number
•
To determine the number of Production Cards in the system, take the
highest available Cards to be shipped on one truck and add one Card.
•
EXAMPLE:
• Truck 4 = 6 Cards
• 6 Cards + 1 Card = 7 Cards
• (7) Production Cards Required
•
Note: Additional Cards may be required for longer lead-times
79
KB001
Kanban A New Approach
Card Placement
•
To determine the location of the Production Card on the takt time
post, take the available Cards for the last truck and subtract the
quantity for the first truck and count backwards from the last truck
•
EXAMPLE:
• Truck 4 - Truck 1 = Cards Generated for 1st
•
(6)
- (3)
= 3 Cards for 1st Shift
•
Note: If the number is zero or a negative number, only the last Card
of the last truck is generated for 1st shift

“Tool To Trigger Production”
• Production Card
• High level of capability in the work unit
• Production of parts in any order
117
KB001
Kanban A New Approach
Producing
Card for Card
• If a work unit can produce parts in the same order that they are pulled
from stores, then they produce Card for Card
• The Production Card (typically a white card) is attached to the
container after production
• When a container is pulled from the work unit store, the card is
removed and sent back to the work unit to trigger production
118
KB001
Kanban A New Approach
Points to Remember
• The Production Card is the signal to produce a container of a particular
part number
• The work unit produces in the order that the Production Cards are
received
• Changeover time must be equal to or less than the consumers
changeover time

Signal Triangle
• When using the Signal Triangle, every part number on the work
unit has it’s own signal
• The signal instructs the work unit to produce and is dependent on
how inventory is pulled from the work unit
• If parts are not withdrawn from the work unit, the work unit will not
receive a signal to produce
124

Lot Size Production
• Signal Instructs the Work Unit:
• When to produce the part
• How many to produce at one time

Order Point
• The order point determines how much inventory is needed
in the stores to cover customer requirements during the
work unit’s peak period of downtime
• For instance, the order point = 2
• The signal is placed on the 2nd to the last container. When
the container above the signal on is pulled, exposing the
Signal Triangle, the signal goes back to the line to trigger
production with the corresponding amount of Production

How are the Containers Identified?
• A Production Card is placed on a container after it is
produced
• When the container is pulled from the store the
Production Card is removed and is put into a collection
box, while a Move Card is put on the container in it’s
place
• When the signal is sent to the work unit for production,
the number of Production Cards that are needed to I.D.
the containers are also taken
