RE: Kan Ban

Kanban is a Just-in time mentality. 
Kanban is a method of Just-in-Time production pull system in which work
centers signal with a card that they wish to withdraw parts from feeding
operations or suppliers. The Japanese word kanban, loosely translated, means
card, billboard, or sign.  It intended to be a signal to start your
replenishment process and not an "expedite I am out of inventory now and
needed the inventory yesterday". 

What your customer (partner) forgot to do is set up the Kanban to signal
with enough time for you to replenish their inventory. You should
communicate and educate your partner in the Kanban mythology including what
you need to help meet their requirements.

Al:

Both Lisa Abney and William McAllister have provided very pertinent insight
to the challenge you face when the customer expects zero lead time
replenishments.  Both point out the challenge is not with BPCS; it is with
the information you are receiving.  I'd agree with Ms. Abney when she says
your customer is operating with a JIT mentality.  I'd also suggest the
customer has not accepted all the responsibilities associated with their end
of JIT.  One industry you might want to look at is automotive.

Auto manufacturers operate under JIT and, on the surface, demand zero lead
time replenishment from their vendors.  However nothing could be further
form the truth.

The OEMs (Ford, GM, D/C) use weekly material release authorizations (MRA) to
project their requirements over an extended horizon and daily shipping
schedules to specify "tomorrow's" exact quantities.  When I worked with
these "documents' in the past the MRA came out on Friday and started with a
week from the coming Monday.  The shipping schedule was released at 3 this
afternoon and was for tomorrow.  In short the supplier knows the total
demand for a week one week in advance and what's to be shipped tomorrow one
day in advance.

There were several interesting terms to the OEM/supplier contract.  One, for
example, obligated the OEM to accept (or reimburse for) all authorized
quantities within a specific horizon.  I don't know what the horizon is
today (I've heard recently that it is the first week of the MRA but this is
unconfirmed) however within my experience set the commitment period was the
first 4 weeks of any MRA's horizon.

I'd also point out the current situation forces you into a make to stock
mode.  In this mode you have no choice but to be driven by a forecast, as
suggested by Mr. McAllister.  Where that forecast comes from, in the end, is
immaterial.  Remember neither a customer provided forecast nor an internally
generated one will be accurate.  As a result you'll have too much on the
shelf sometimes and not enough at other times.  The consigned inventory
approach suggested by Ms. Abney offers some relief but there are no silver
bullets, no knockout punches that will take this challenge out.

Have heart, it will get better.

Subject: Fwd: Kan Ban

Do any other companies using BPCS for your ERP have experience with
customers using Kan Ban, where they expect zero lead time for their
parts.  Whenever they run low on the Kan Ban parts, they call us, and
expect immediate shipment of whatever quantity they ask for, using us like
a warehouse with safety stock of the end parts.  Is there another name for
this phenomena where "Kan Ban" is not the right terminology?

Can anyone suggest pros and cons of different ways of handling this
business?
I expect that BPCS can handle it, using some aspects of BPCS with which we
are inexperienced.
We are on BPCS 405 CD mixed mode AS/400 V5R1
We are doing engineering, costs, orders, inventory, by facility.

This Kan Ban concept is new to our BPCS users.  Some co-workers seem to
think safety stock is working Ok, while others seem to think our methods
are not working right for the Kan Ban parts.  I think the whole issue of
what is working, and what is not working, is complicated by us accepting a
whole bunch of parts new to BPCS in which we are trying to make them before
the BOM and Routings get completed, so we are getting to experience reality
for BPCS users not yet ready to use MRP as it is designed to be used, for
those new parts with the engineering backlog.

We are accustomed to driving MRP using customer orders due on various dates
a few weeks into the future.  If Kan Ban is to be shipped when customer
calls, should Post Ship Billing be used instead?
