Supplier Kanban is based on the Kanban principle, but goes beyond the company boundaries and includes the suppliers in the principle. In contrast to Kanban, in supplier Kanban the point of consumption does not report its requirements to an internal supply point but to an external supplier. This has the necessary products on stock. A goal of supplier Kanban is - like with Kanban - a demand-controlled part supply, which takes place here by the one external supplier. The demand determination takes place mainly over Kanban containers, eKanban, transponder or RFID. Upon delivery and after an incoming inspection and booking, the parts flow directly into the internal Kanban system.
