Question

If a process has a capability index of 1 and is running normally (centered on the mean), what percentage of the units would one expect to be defective?

Short answer

Using capability indices, procedure capability contrasts the outcome of an in-control procedure to the specified boundaries.

Step-by-step solution

Capability index

Capability Indexis the proportions of procedure as well as requirement spread. They are unitless values that may be used to contrast the capabilities of various processes. Many capability indexes take into account the procedure mean as well as the goal.

Six Sigma is an analytical phrase that refers to the number of faults that procedures generate. Since a Six Sigma system permits just 2.7 defects per thousand possibilities, the word suggests superior efficiency.

The Design limits are at $\pm 3\sigma$2.7 defects per thousand. The procedure capability Index, as well as method capability proportion, is a measurable statistic of processing ability used in enhancement initiatives: the capacity of a system to deliver the output within standard constraints. The idea of process capability is only applicable to statistically controllable systems.
