Capability is defined as the likelihood a product will meet its designed specifications. Capability Analysis is a set of statistical calculations performed on a set of data in order to determine the capability of the system. A system is said to be “capable” if it meets 100 of its specifications. However, to be 3-sigma it only needs to meet 99.73 of specifications. Specifications are also referred to as requirements, goals, objectives, or standards-Capability is defined as the likelihood a product will meet its designed specifications.　Capability Analysis is a set of statistical calculations performed on a set of data in order to determine the capability of the system.　A system is said to be “capable” if it meets 100　of its specifications.
