Techopedia Explains Deming Cycle

William Edwards Deming learned about statistical modeling as a way to control and improve industrial processes from Walter A. Shewhart of Bell Labs. He took his knowledge to Japan in the late 1940s, where the techniques were widely adopted by industry and further developed by the Japanese. In the 1980s, the Deming/Shewhart techniques caught on in the U.S. due to the growing quality and production gap between American and Japanese automakers. The increasing power of software and hardware has made it possible for developers to distill the Deming cycle down into algorithms that can be used for business analytics and organizational planning.
