Just in time (JIT) is a production strategy that strives to improve a business return on investment by reducing in-processinventory and associated carrying costs. Just-in-time production method is also called the Toyota Production System. To meet JIT objectives, the process relies on signals or Kanban (看板 Kanban?) between different points in the process, which tell production when to make the next part. Kanban are usually 'tickets ' but can be simple visual signals, such as the presence or absence of a part on a shelf. Implemented correctly, JIT focuses on continuous improvement and can improve a manufacturing organization 's return on investment, quality, and efficiency. To achieve continuous improvement key areas of focus could be flow,…show more content…
Kanban cards, in keeping with the principles of Kanban, should simply convey the need for more materials. A red card lying in an empty parts cart would easily convey to whomever it would concern that more parts are needed.
In the last few years, Electronic Kanban systems, which send Kanban signals electronically, have become more widespread. While this is leading to a reduction in the use of Kanban cards in aggregate, it is common in modern Lean production facilities to still find widespread usage of Kanban cards.[citation needed] This system is also available in enterprise resource planning software such as SAP ERP.[citation needed]
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the subsequent process * The subsequent process comes to withdraw only what is needed * Produce only the exact quantity withdrawn by the subsequent process * Level the production * Kanban is a means to fine tuning * Stabilize and rationalize the process

Three-bin system
A simple example of the kanban system implementation might be a "three-bin system" for the supplied parts (where there is no in-house manufacturing) — one bin on the factory floor (demand point), one bin in the factory store, and one bin at the
