Wider effects of JIT
• Suppliers: JIT relies totally on its suppliers – so it supports the view of customers and suppliers working closely together in long-term partnerships pursuing common objectives.
• Batch size: Operations often use large batch sizes, as they reduce set-up costs and disruptions. But if demand is low, the products made in large batches sit in stock for a long time. JIT looks for ways of reducing the batch size so that it more closely matches demand.
