193 1 year, the landmark book Economic Control of Product Manufacturing Quality was published, which comprehensively expounded the basic principles of quality control. Shewhart believes that the quality of products is not detected, but produced. The focus of quality control should be on the manufacturing stage, and the quality control afterwards should be promoted to the quality control beforehand.

The basic theory of control chart put forward by Dr. shewhart;

The fluctuation of (1) in all manufacturing processes has two components. The first component is the stable component caused by internal process (that is, accidental fluctuation), and the second component is the intermittent fluctuation (abnormal fluctuation) with identifiable causes.

(2) those abnormal fluctuations that can be identified can be found by effective methods and can be removed. But occasional fluctuations will not disappear unless the basic process is changed.

3 based on 3? The limit control chart can distinguish accidental fluctuation from abnormal fluctuation.

PDCA (Plan-Implement-Check-Deal) cycle was also put forward by shewhart, and was later adopted, publicized and popularized by Deming, so it is also called? Pdsa？ . With the deepening of the concept of total quality management, this cycle has been widely used to continuously improve product quality and achieved good results.
