Using the terminology of statistical process control (SPC), Type I errors are where common cause variation is treated as assignable cause variation. Some examples of manufacturing process waste are rework, scrap and excessive inspection time. A C pk index value of 1 is ideal, meaning all units meet specifications. Statistical process control (SPC) is a systematic decision making tool which uses statistical-based techniques to monitor and control a process to advance the quality or uniformity of the output of a process – usually a manufacturing process.
