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.
