The 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 which are not expected, such as misaligned, damaged, or worn equipment. Process capability indices measure how much "natural variation" a …

WebbCp (eng. capability process) Cp-talet beskriver processdugligheten och är det antal gånger som processens spridning får plats inom toleransvidden. Ju större Cp-tal desto bättre process. Exempel: Om Cp är 2,0 får processens spridning plats två gånger i toleransvidden, medan Cp 1,0 betyder att den får plats en gång.
