A definition of the term statistical process control is presented. It refers to a means of monitoring a process to assist in identifying causes of variation with the goal of improving process performance. Statistical process control consists of three elements: data gathering; determining control ...
Other SPC/SQC advocates further elaborate this concept by differentiating these terms according to the type of data elaborated by the tools: SPC is based on process signal data analysis, while SQC is based on product feature-related data.

process within control limits before it drifts out to some unacceptable value. The control parameter can be either a variable or an attribute. Accordingly, there are two basic types of control charts: control charts for variables (X-bar charts, range charts) and control charts for attributes (...
