Only by ensuring "zero defects" can the goal of zero defects and zero inventory pursued by JIT production be realized. JIT production mode requires zero defects and zero inventory in all links of supply, production and marketing, which requires all links of production and operation to coordinate with each other, run smoothly and ensure high quality. Due to the close connection between various activities in the production process, the defects in a certain link will cause chaos in production, cause chain reactions, and cause the collapse of the timely production system, with incalculable losses. Therefore, when an enterprise should implement JIT production, it should mobilize all employees to actively participate. From the selection of suppliers to the design of products, the determination of production processes, and the production and sales of products, quality management should be strengthened in all stages. Through the self-control of relevant personnel, defects should be eliminated in real time, thus realizing zero defects in the production and operation process.
