KANBAN

BYRAHUL SHRIRAO

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

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.

Produce only the exact quantity that was withdrawn by the subsequent process.

Level the production.

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.

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.

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

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.
