QA/QC Introduction

In all production processes, we need to monitor the extent to which our products meet specifications. In the most general terms, there are two "enemies" of product quality: (1) deviations from target specifications, and (2) excessive variability around target specifications. During the earlier stages of developing the production process, designed experiments are often used to optimize these two quality characteristics; the methods provided in Quality Control are on-line or in-process quality control procedures to monitor an on-going production process.
