On the road of company management, because of the different market operations, the variability of enterprise resources and the external environment, there will be many problems, which is the norm and the source of "why there are always quality problems". Just imagine, an enterprise has no quality problems, just as we are individuals, it is impossible to have no discomfort from childhood to adulthood. The body without fault is God; An enterprise without quality problems is not an enterprise, but a divine industry.Accept the inevitability of the existence of quality problems, and make the pursuit of quality problems to solve them a pursuit and requirement, just like "zero defect" is an ultimate goal, through the prevention system and process control, to guide the continuous improvement of quality. In the same way, we should also see all the unsatisfactory that we may encounter in life as an inevitability, accept, think about and solve it.
