Which one of the following is a defining feature of a JIT purchasing arrangement between a manufacturer and its suppliers?
JIT purchasing uses few certified suppliers on long-term contracts who deliver small quantities frequently and with assured quality. This removes incoming inspection and buffer stock. Bulk orders, frequent re-bidding among many suppliers, or month-long buffers are features of traditional purchasing, not JIT.
- ALarge bulk orders placed quarterly to earn volume discounts
- BLong-term contracts with few certified suppliers making frequent small deliveries of defect-free materialCorrect
- CCompetitive bidding every month among many suppliers to lowest price
- DHolding buffer stock equal to one month of consumption
Explanation
JIT purchasing relies on a small number of reliable suppliers under long-term agreements, delivering small lots frequently with assured quality, so inspection and buffer stock are minimised. Bulk quarterly orders, monthly bidding and buffer stocks all contradict this approach.
