What fundamental principle does Just In Time (JIT) production rely on?

Just In Time (JIT) production is primarily based on the principle of delivering materials exactly when they are needed in the production process. This approach minimizes inventory levels, reduces carrying costs, and enhances efficiency by eliminating waste associated with overproduction and excessive stock. The JIT methodology focuses on synchronizing production schedules with demand, ensuring that materials arrive just in time for processing, thereby streamlining operations and improving response to customer needs. This system fosters greater flexibility, allowing businesses to adapt quickly to changes in demand while maintaining lower inventory levels, ultimately leading to more efficient and cost-effective production.
