Hey everyone, welcome to this lecture. What is the history of statistical process control? statistical process control is not new to the industry. In 1924, William H shewhart developed the control chart and the concept that process could be in statistical control. He worked at the Bell Laboratories. He kept working on this concept and eventually published a book titled, economic control of quality of manufactured product in 1931, published by Van Nostrand in New York.

This book set the tone for subsequent applications of statistical methods to process control. statistical process control gained wide usage during World War Two by the military in munitions and weapons facilities. The demand for product had forced them to look for a better And more efficient way to monitor quality without compromising safety, statistical process control failed that need. W Edwards Deming invited to Harvard to speak at the Graduate School of the US Department of Agriculture, and served as the editor of shoe Hart's book statistical method from the viewpoint of quality control, published in 1939, which was a result of that lecture. Deming was an important architect of the quality control short courses that trained American industry in the new technologies during World War Two. The graduates of these wartime courses formed a new professional society in 1945.

The American Society for Quality Control, which is today known as the American Society for Quality or a Sq Deming was elected as its first president. Deming traveled to Japan during the Allied occupation and met with the union of Japanese scientists and engineers. Jews, in an effort to introduce statistical process control methods to Japanese industry. In 1970s, SPC started to gain acceptance, again due to American industry feeling the pressure from high quality products being imported from Japan. Today, statistical process control is a widely used quality tool throughout many industries.
