Just-in-time (JIT) production

Definition

Just-in-time (JIT) production is a manufacturing strategy that aims to reduce waste by receiving goods only as they are needed in the production process, thereby minimizing inventory costs. This approach connects closely with global supply chains as it relies heavily on precise coordination and communication between suppliers and manufacturers, ensuring that materials arrive exactly when required to meet production schedules.

5 Must Know Facts For Your Next Test

1. JIT production originated in Japan during the post-World War II era, particularly within Toyota's manufacturing system, aiming for efficiency and quality.
2. This method significantly reduces the holding costs associated with large inventories, allowing firms to allocate resources more effectively.
3. JIT requires strong relationships with suppliers to ensure timely delivery of materials, which can lead to vulnerabilities if disruptions occur.
4. The implementation of JIT production can lead to shorter lead times and increased responsiveness to market demands, enhancing competitiveness.
5. Technology plays a crucial role in JIT systems, with advancements in logistics, inventory management software, and communication systems being essential for success.
