Just-In-Time is a methodology that synchronizes the delivery of materials or components with production schedules, ensuring that inventory arrives precisely when needed. JIT reduces storage costs, eliminates unnecessary stockpiling, and improves cash flow while maintaining production efficiency. The system relies heavily on demand forecasting, reliable suppliers, efficient transportation networks, and coordination across departments. In logistics, JIT helps minimize waste, enhance responsiveness, and align supply with actual market demand, making it a key strategy in lean manufacturing and supply chain optimization.
