2. it is a scheduling system
for lean and just-in-time (JIT)
production
Kanban was developed by Taiichi
Ohno, at Toyota, to find a system to improve
and maintain a high level of production
3. Taiichi Ohno stated that to be effective, kanban
must follow strict rules of use
Toyota's Six Rules
Do not send defective products to the subsequent process.
.
The subsequent process comes to withdraw only what is
needed.
4. Produce only the exact quantity that was withdrawn by the
subsequent process.
Level the production.
Kanban is a means of fine tuning.
Stabilize and rationalize the process
5. Kanban cards
Kanban cards are a key component of kanban and signal the
need to move materials within a manufacturing or
production facility or move materials from an outside
supplier in to the production facility.
6. The kanban card is, in effect, a message that signals that there
is a depletion of product, parts, or inventory that, when
received, the kanban will trigger the replenishment of that
product, part, or inventory
It is widely held[citation needed] by proponents of lean
production and manufacturing that demand-driven systems
lead to faster turnarounds in production and lower inventory
levels, thereby helping companies implementing such systems
to be more competitive.
7. In the last few years, systems sending kanban signals
electronically have become more widespread. While
this trend is leading to a reduction in the use of kanban
cards in aggregate
In Oracle ERP (enterprise resource planning), kanban is
used for signaling demand to vendors through e-mail
notifications
8. A Red card lying in an empty parts cart conveys
that more parts are needed.
Three-bin system
One bin is on the factory floor (the initial demand point), one bin is
in the factory store (the inventory control point), and one bin is at
the supplier's business. The bins usually have a removable card
containing the product details and other relevant information — the
classic kanban card.
