Hey everyone, welcome to this lecture. What is konban? imagine a scenario of a supermarket. When the customer takes away specific items from the store shelf, they are replenished. If a customer does not use an item, it continues to sit on the store shelf and is not replenished. There is no more overproduction than the small amount on the shelf, and there is at least some direct connection between what customers want and what the company produces.
However, factories can be large and spread out. suppliers of parts are generally a distance away. Thus, taiichi Ohno, the creator of Toyota Production System, looked for a way to signal that the assembly line had used the parts and needed more. He used simple signals, such as guards, empty bins, empty carts, called Kanban Convert means sign, signboard door played poster billboard card, but it is taken more broadly as a signal of some kind. Send back and empty Ben can ban and it is a signal to refill it with a specific number of parts or send back a card with detailed information regarding the part and its location. An empty bin with a Kanban card is a signal for production to pull material from the previous step.
The Kanban quantify is mathematically calculated and fine tuned during practical implementation. Typically, organizations take a while to perfect the Kanban. Why is konban used a system is best controlled when material and information flows into and out of the process in a smooth and rational manner. If process for Materials arrive before they are needed. Unnecessary confusion, inventory and costs generally occur. If the process outputs are not synchronized with downstream processes, delays, disappointed customers and associated costs may occur.
Properly administered Kanban system will improve system control by assuring timely movement of products and information. When it's combined used Kanban is a more mature concept. It is important that other fundamentals of lean such as five s Standard Work etc. are put in place before venturing into Kanban If not, frequent equipment failure and unstable or inconsistent processes will defeat the purpose of Kanban resulting in huge konban sizes to shield against these uncertainties with This description of konban we are all set to end this lecture. Thank you for attending. See you in the next one.
