Deming saw all of the elements as vital in achieving TQM. Thus SQC, as distinct from TQM, is based on continuous sampling and measurement against a standard and immediate corrective action if measurements deviate from an acceptable range. If measurements begin to fall outside the band or show an undesirable trend (up or down), the process is stopped and production discontinued until the causes of divergence are found and corrected.

Samples are continuously taken and immediately measured, the measurements recorded on the chart(s). Quality control then begins during the production process itself. This 'band' of acceptable outcomes is then recorded on one or several Shewhart charts. Test runs are made to establish divergences from a base measurement (up or down) which are still acceptable.

The measurements may be dimensions, chemical composition, reflectivity, etc.-in effect any measurable feature of the object. In a nutshell, this core method requires that quality standards are first set by establishing measurements for a particular item and thus defining what constitutes quality. But while the quality movement has continued to evolve beyond its beginnings, many of Deming's particular emphases, particularly those associated with management principles and employee relations, were not adopted in Deming's sense but continued as changing fads, including, for example, the movement to 'empower' employees and to make 'teams' central to all activities. Total Quality Management, the phrase applied to quality initiatives proffered by Deming and other management gurus, became a staple of American enterprise by the late 1980s. Deming's approach to quality control came to be recognized in the United States, and Deming himself became a sought-after lecturer and author. producers scrambled to adopt quality and productivity techniques that might restore their competitiveness. This led to the spread of the quality movement across the world. Japanese application of the method had significant and undeniable results manifesting as dramatic increases in Japanese product quality-and Japanese success in exports. They also invited Joseph Juran to lecture in 1954 Juran was also enthusiastically received. Japan began a process of implementing what came to be known as TQM. He found Japanese executive receptive to his ideas. In his lectures on SQC Deming promoted his own ideas along with the technique, namely a much greater involvement of the ordinary worker in the quality process and the application of the new statistical tools. Management and engineers controlled the process line workers played a small role. during the war, particularly methods of quality control. Deming had developed a critical view of production methods in the U.S.

A series of lectures took place in 1950 under the auspices of the Japanese Union of Scientists and Engineers (JUSE). They invited Deming to lecture on the subject. The Japanese were already aware of Shewhart's methods of statistical quality control. State Department to help Japan in the preparation of the 1951 Japanese Census. Edwards Deming, trained as a mathematician and statistician, went to Japan at the behest of the U.S.
