WebbStatistical Process Control Charts are utilized to determine if the process is stable or not. Some charts are used to assess the stability of the process location (e.g. xbar charts which monitor the process average), other charts are used to assess the stability of the process variation (e.g. range or standard deviation charts).. Process Capability is a measure of … WebbThe process capability index, or process capability ratio, is a statistical measure of process capability: the ability of an engineering process to produce an output within specification limits. The concept of process capability only holds meaning for processes that are in a state of statistical control.This means it cannot account for deviations …
