Statistical Quality Control

Background:

Statistical Quality Control (SQC) is the term used to describe the set of statistical tools used by quality professionals to help them identify quality problems in the production process as well as the product. Statistical quality control can be divided into three broad categories – Descriptive Statistics, Statistical process control (SPC) and Acceptance sampling. The tools in each of these categories provide different types of information for use in analyzing quality. Descriptive statistics are used to describe certain quality characteristics, such as the central tendency and variability of observed data.

Although descriptions of certain characteristics are helpful, they are not enough to help us evaluate whether there is a problem with quality. Acceptance sampling can help us do this. Acceptance sampling helps us decide whether desirable quality has been achieved for a batch of products, and whether to accept or reject the items produced. Although this information is helpful in making the quality acceptance decision after the product has been produced, it does not help us identify and catch a quality problem during the production process. For this we need tools in the statistical process control (SPC) category. All three of these statistical quality control categories are helpful in measuring and evaluating the quality of products or services.
