Which of the following is a characteristic of just-in-time inventory management systems?

Just-in-Time (JIT) is an inventory strategy focused on increasing efficiency and decreasing waste by receiving goods only as they are needed in the production process. A core tenet of JIT is the elimination of buffer or safety stock. Without this inventory cushion, the entire production line is vulnerable to disruptions. Therefore, a JIT system is critically dependent on suppliers providing materials that are of consistently high quality and free of defects. The arrival of a single defective batch could halt all production, making high-quality inputs a fundamental prerequisite for the system's success.

A. JIT systems are designed to minimize or completely eliminate safety stocks, not to have users determine an optimal level. The goal is near-zero inventory.

B. While pioneered by large organizations like Toyota, JIT principles are scalable and can be successfully implemented in small and medium-sized enterprises.

C. This is a common criticism of poorly implemented JIT, not an inherent characteristic. A true JIT system aims to improve efficiency across the entire supply chain, not just shift inventory costs to suppliers.

"Quality is critical to the JIT partner. The buyer cannot afford to process

bad parts." (p. 661).

Lecture 10: Lean Production. Massachusetts Institute of Technology. The lecture notes explain that a pillar of the Toyota Production System (the foundation of JIT) is "Jidoka" or "quality at the source

" which necessitates high-quality inputs to prevent defects from moving down the production line.
