In Lean methodology, what does 'Pull' refer to?

In Lean methodology, 'Pull' refers to driving production by actual customer demand. This principle contrasts with a 'Push' system, where products are created based on forecasts or internal schedules without direct input from customer demands. The 'Pull' approach ensures that resources are utilized efficiently, minimizing waste and excess inventory. By aligning production closely with real-time customer needs, companies can respond more effectively to market demands and maintain a steady flow of goods, thereby enhancing overall efficiency and customer satisfaction. This practice is a core element of Lean thinking, focusing on producing only what is needed, when it is needed, and in the quantity required.
