Article Abstract

Statistical Process Control (SPC) is defined as the application of statistical techniques to provide information necessary to control or improve processes throughout the life cycle of a product or service. Simply stated, SPC is a method of management using numerical information.Statistical Techniques, the tools of SPC, transform raw data into useful information for decision-making. An understanding of basic SPC techniques together with knowledge of the process enable practitioners to acquire accurate and relevant information. The key to judicious application of statistical techniques is knowledge of the process, not statistics per se.The current emphasis on quality technology in industry has produced a plethora of antidotes concerning the use, misuse, and overuse of SPC. The conflicts and confusions over application stem from several basic misconceptions about the method that represent impediments to implementation.
