“You can’t manage what you can’t measure” is a famous quote from W. Edwards Deming, the quality guru of the 1980s. When it comes to the plastic injection molding process, Michael Durina, founder of Md Plastics, put his own spin on this saying: “You can’t manage what you can’t control, and you can’t control what you can’t measure.”

The Benefits of Statistical Process Control
Statistical process control (SPC) is a method of quality control which employs statistical methods to monitor and control a process. This helps to ensure that the process operates efficiently, producing more specification-conforming products with less waste
[1].
The concepts of statistical process control were initially developed by Dr. Walter Shewhart of Bell Laboratories in the 1920s, and were expanded upon by Dr. W. Edwards Deming, who introduced SPC to Japanese industry after WWII. After early successful adoption by Japanese firms, SPC has now been incorporated by organizations around the world as a primary tool to improve product quality by reducing process variation

Laurence (“Larry”) Smith is a long-time advocate of quality and systems-thinking-based management of U.S. businesses. In the early 1980s, while he was leading a chamber of commerce in northeastern Massachusetts, Smith recognized “the need for a transformation of American management,” he told me recently. A learning experience that inspired him to appreciate a holistic, systems view of business leadership and management was a four-day workshop his chamber sponsored in his community by the late Dr. W. Edwards Deming. “I learned to think of quality as a 360-degree process that includes quality of life,” Smith recalled recently.
