What is Capability Analysis?
Capability analysis is a set of statistical calculations performed on a set of data in order to determine the capability of the system. The capability of the system refers to the ability of the system to perform in comparision to its specification limits. A system is said to be “capable” if it is producing approximately 100% within specification limits. Specification limits are set by customers, engineering, or management. They are sometimes called requirements, goals, objectives, or standards. Specification limits are upper and lower boundaries within which the system must operate. They are not to be confused with control limits, which are based on the data collected from the system.
