Control charts
Control charts are used to monitor the performance of processes and detect statistically significant (i.e. non-random) deviations. Based on the results of the control card, the process is controlled (see also Control loop).
A control chart, also referred to as quality control chart or QCC, is applied to statistical process control. A QCC generally consists of a level path and a dispersion path together with specified action limits. The sample averages and standard deviations, for example, may be entered in the corresponding path of the QCC. (from VDA Volume 5)
