https://doi.org/10.1351/goldbook.08099
Process subject only to random causes.
Notes:
  1. The random variation is considered to follow a Gaussian distribution and is characterized by its variance (standard deviation)
  2. This state does not imply that the random variation is large or small, within or outside of specification, but rather that the variation is predictable using statistical techniques.
  3. A control chart can be used to monitor a process and to determine whether the process is, or is not, in a state of statistical control. See out-of-control criteria and control limit.
