A specific application of Kanban, used in coordinating vendor replenishment activities. In making bread or other route type deliveries, the deliveryman typically arrives at the customer's location and fills a designated container or storage location with product. The size of the order is not specified on an ongoing basis, nor does the customer even specify requirements for each individual delivery. Instead, the supplier assumes the responsibility for quantifying the need against a prearranged set of rules and delivers the requisite quantity.
