A pull system is a lean manufacturing technique to reduce waste from any production process. The application of a pull system allows starting a new job only when there is a demand for the product from the customer. This provides the opportunity to reduce overhead and optimize storage costs.
Pull systems are part of the lean manufacturing principles, born in the late 1940s. A pull system is intended to create a workflow where work is done only if there is a demand for it.
