3. What you need prior to start ?
Define the Point of Use
A place to put Kanban
The right number of Kanban
A runner/collector of Kanban
4. Real Example
A point of use (POU) needs balls in 6 pcs / boxes
Consumption is 18 balls / day
The runner pass every day at 10:00 am
The Lead Time to recieve from warehouse = 2 days
Safety Stock fixed at 20%
This means => 8 Kanban Cards in WIP
45. Friday 17:00 PM – End of Work
POU
Warehouse
Next Week the same cycle ...
46. Some Considerations
The WIP is under control (48 balls in 8 boxes)
Is the system too risky of stock-out in the POU and why?
Looking carefully at the lead time, if the collector comes
at 10.00 AM, the POU start at 8.00 AM and the
warehouse brings the boxes at 9.00 AM the lead time to
consider is not 2 days but 2 days and 3 hours.
In this case the correct lead time to use is round 2.5 days
and the kanban system need is:
9 Kanban Cards rather than 8 Kanban Cards
47. Some Considerations
At the beginning of Kanban Implemetation starts with a
safe number of kanban cards and then reduced it when
the system will be stable and reliable.
