What Are Kanban Cards?

Kanban management refers to a tool that controls the on-site production process in order to achieve the JIT just-in-time production method. The mainstream business management education has introduced "kanban", a management tool derived from Toyota's production method.

1. Master production plan

The theory of Kanban management does not involve how to prepare and maintain the main production plan. It starts with an existing main production plan. So adopt

1. Regardless of whether it is a production kanban or a transmission kanban, it must be attached to a container containing parts when it is used. 2. It is necessary to pick up the parts by transmitting the kanban from the buyer to the supplier, or send a signal to the supplier, and the supplier transfers the parts by transmitting the kanban. In short, the parts must be transferred according to the requirements of the acquirer, and no parts must be transferred without the kanban. 3. Use standard containers. Do not use non-standard containers or use standard containers but do not put them in standard quantities. This reduces the time required for handling and counting and prevents damage to parts. 4. When a production kanban is taken out of the production kanban box, only the number of parts contained in a standard container is produced. 5. Defective products are not delivered to the next process. ^[1]

1. Kanban within the process. Refers to the kanban used in a certain process. This type of kanban is used in assembly lines and processes that do not require substantial job replacement time (near zero job replacement time), such as machining processes, even when producing multiple products. The so-called kanban is also called a card, but in fact, the form of the kanban is not limited to a certain card form in which various information is recorded. The essence of kanban is to issue the required parts and components at the required time and in the required amount.

The electronic kanban system is mainly composed of two parts: a kanban controller and a display terminal. The display terminals to which the controller can be connected include various displays and a flat-screen TV. ^[1]

1) Work instructions for production and shipping

Kanban records information such as production volume, time, method, sequence, and transportation volume, transportation time, transportation destination, storage location, and transportation tools. They are traced from the assembly process to the process. Take off the kanban, and then go to the previous process to collect it. "Post process receipt" and "just in time and right amount of production" are achieved through Kanban. ^[1]

The so-called kanban method is a production management method developed and adopted by Toyota Motor Corporation to reduce inventory. The management method is based on the just idea of just-in-time production, producing (preparing) the required products in the required quantity when needed. The "kanban method" is used because it uses what is called a "kanban" that has both work instruction cards and spot cards as the central means. ^[1]
