The development of quality management and industrial production technology and management is closely related to the development of science. Modern concept of quality, including on the social, economic and systematic understanding of three aspects.
Quality of social
The quality of not only direct users, but from the perspective of society as a whole to evaluate, particularly in relation to production safety, environmental pollution, ecological balance, especially when other issues.
Quality of the economy
Quality not only from some of the technical indicators to consider, but also from the manufacturing cost, price, value and consumption aspects to a comprehensive evaluation. In determining the quality level or target, can not be divorced from social conditions and needs, not simply the pursuit of advanced technology, should also consider the use of economic rationality, the quality and price to achieve a reasonable balance.
Quality is a subject to design, manufacture, use and other factors affecting the complexity of the system. For example, the car is a complex mechanical system, is also involved in the road, drivers, passengers, cargo, transportation system and other features using the system. Quality of the product should achieve multi-dimensional evaluation of the target. Feigenbaum believes that a quality system is to determine the quality standards for the delivery of products and necessary steps to manage and technical network.
The development of quality management to total quality management, quality management and is a big improvement, statistical quality management focused on the application of statistical methods to control production process quality management to play a preventive role, to ensure product quality. However, the formation of not only product quality and production process, but also with many other processes, and factors associated with many areas, it is not relying solely on statistical quality control can be resolved. Total quality management is relatively more responsive to modern mass production of quality holistic, comprehensive and objective requirements, limited to localized management from the past to further the comprehensive and systematic management.
