In Lean Framework, what does 'pull' refer to?

In the Lean Framework, 'pull' refers to a system where production is driven by actual demand rather than forecasts or predetermined schedules. This approach aligns closely with just-in-time principles, where items are produced only when there is a specific need for them. By focusing on demand-driven processes, organizations can reduce waste and improve efficiency, ensuring that they produce only what is required, thereby minimizing overproduction and excessive inventory.

This concept directly contrasts with mass production, which is focused on creating large volumes of items regardless of current demand. Instead of pushing products through the system based on estimates, the pull system reacts to real-time needs, allowing for a more responsive and agile operation. This methodology not only helps in optimizing resource use but also enhances customer satisfaction by providing products that match their actual requirements at the right time.
