Several quality guru’s, such as W. Edwards Deming. Philip B. Crosby, and Joseph M. Juran, has made significant contributions in the field of quality. They are largely responsible for the global adoption and integration of quality management in industry. They preached that management commitment is the key to a successful program in quality. They also emphasized that any philosophy to improve quality in a company needs time and cannot occur overnight.

WW. Edwards Deming is credited with the impressive turnaround in Japanese industry after World War II.  Deming's philosophy emphasizes the role of ‘management of the problems’ that indus­try faces. Deming said that about 85% of the problem can be solved only by management. These involve changing the method of operation and are not by scolding the workers. His idea was to improve process and not on blaming or scolding workers. In Deming's world, workers' responsibility lies in communicating to management the information they possess regarding the process and both must work in harmony. The Deming's ideal management style is holistic and organization is viewed as an integrated entity. The idea is to plan for the long run and provide a course of action for the short run. Deming believed in the adoption of a total quality philosophy and emphasized the never ending nature of statistical quality control in the quality improvement process. Deming's approach demands a cultural transformation in the organization.  Deming advocated certain key components that are essential for the journey to­ward continuous improvement, viz. Knowledge of the system and the theory of optimization(to look into system as a whole and not as individual process), Knowledge of the theory of variation( understanding common and special cause of variation and emphasize on statistical process control), Exposure to the theory of knowledge(data driven prediction that is based on underlying knowledge about processes), Knowledge of psychology (understand the behavior and interactions of people and also the interactions of people with their working environment). Deming provides 14 points for management that will sustain productivity and competitiveness of the com­pany in the long run. Book by Deming (published in 1982, 2000)or any book on Quality Management can be seen by readers to understand in-depth the 14 points. In around 1950, Shewart cycle was renamed in Japan as Deming PDCA cycle.
