What is the primary purpose of the 'Establish pull' step in Lean?

The primary purpose of the 'Establish pull' step in Lean is to order materials based on actual need. This step emphasizes producing or delivering products only when there is a demand for them, thereby minimizing waste associated with excess inventory and overproduction. In a pull system, production is driven by actual consumption, ensuring that resources are utilized efficiently and effectively. This approach helps to align inventory management with real-time customer demand, allowing for greater flexibility and responsiveness in the supply chain.

By focusing on actual needs rather than forecasts or estimates, organizations can reduce the risk of overproduction, lower storage costs, and improve overall operational efficiency. This principle is central to Lean methodology, which aims to streamline processes and provide value to customers by eliminating non-value-added activities.
