ABSTRACT
While the previous chapter on real-time process control was relatively straightforward, this section is relatively complex, tedious, and never ending. In fact, getting all of the known hardware problems fixed is merely a prerequisite for the main event: improving the quality of your product. This is where statistical process control (SPC) takes over. SPC enables you to dig much deeper to find the root causes of product variability and is therefore an essential element of modern manufacturing.
