What is the significance and function of lean production?

Demand pull The purpose of demand pull is to pull the value stream. From "department" and "batch" to "production team" and "process", the first visible effect is that the time required from conceptual production, sales to delivery, and raw materials to customers is greatly reduced, and may increase several times or even dozens of times. After the introduction of mobility, products that take several years to design can be completed in a few months; Goods that take a few days to complete can be completed in a few hours. In addition, the lean system can now combine all the products being produced at will, so it can meet the changing needs in time. This idea of lean management can also save huge amounts of money from the decline of inventory and the acceleration of bonus turnover. Lean management is a revolutionary achievement. Because, once you have the ability to design, schedule and manufacture products that customers really need when they need them, it means that enterprises can put aside sales forecasts and directly produce according to the actual requirements told by customers. In computer manufacturing, Dell is a typical model. In other words, enterprises can let customers pull products from enterprises according to their needs, instead of pushing products that customers don't want to customers. When users know that they can get what they want right away, and when producers stop regular price-cutting sales activities and stop selling products that have been produced but don't want, users' demand becomes much more stable.
