1- Statistical definition: a statistical measure of the inherent process variability for a given characteristic. The most widely accepted formula for process capability is the 6 sigma range of common ...

(Cp) Statistical process control; the ratio of the tolerance limits (specification window or upper specification minus the lower specification) of a process to the natural variation of that process (estimated by six times the standard deviation of the process output)

A measure of how well a given process is functioning. It is dependant on a calculation of the total probability of defect reflected through short-term variation. Generally expressed: ST=6 or ST=6 which means the total probability of defect is 3.4 defects per million opportunities over the short term.

a comparison of the actual variability of a process to the process specification.

A statistical indicator that measures how close a process is running to its specification limits

(1) A statistical measure of the inherent process variability for a given characteristic. (2) a measurement of the variability in a process to some specification criteria. (3) the number of standard deviations that will fit between the target value and the specification limit, i.e. A process with 6 sigma capability can fit 6 standard deviations between the target and the upper or lower specification limit. A higher value indicates a more capable process.

1. A statistical measure indicating the inherent variation for a given event in a stable process, usually defined as the process width divided by 6 sigma. 2. Competence of the process, based on tested performance, to achieve certain results.

Process capability refers to the ability of a process to produce a defect-free product or service. Various indicators are used-some address overall performance, some address potential performance.

The amount of variation in the output of a controlled manufacturing process, the range defined by plus or minus three standard deviations.

The Process Capability Study answers the question, "is my process good enough?" This is quite different from the question answered by a Control chart, which is, "has my process changed?"
