How to understand the three stages of quality management Almost all enterprises will make great efforts on product quality. It is said in the book that it is called quality management. According to a quality management master named Zhu Lan, quality management has three stages. At first, it is the quality inspection stage. At that time, the enterprise managers thought that the product quality was inspected, because the products with poor quality can be picked out through inspection. Later, they found that it was only an afterthought inspection. All the stories happened, The loss of repair and scrap cannot be avoided. These losses are profits, so we should consider whether we can control the quality in the manufacturing process? This is the second stage of quality management: statistical quality management. At this stage, the famous seven quality management tools, old and new, came on the scene. The application of statistics in quality management has been brought into full play. We have become more and more scientific in terms of quality improvement and more respect for data. Later, people found that simply controlling the quality in the manufacturing process could not be controlled, and the cost was not low. Some product defects were congenital, and many products were lying on the stretcher from the womb. At this time, people realized that the product quality was designed, which was the third stage of quality management: the total quality management stage. At this time, quality management tools such as 6SIGMA and QBD began to be applied to product planning and design by some enterprises, which started to design quality from the very beginning. These enterprises were prescient.
