What is Preliminary Process Capability Index (Ppk)?
Ppk is a file of process execution which tells how well a framework is meeting specifications. Ppk counts utilize genuine sigma (sigma of the individuals), and indicates how the framework is really running when contrasted with the particulars. This file additionally considers how well the process is focused inside the detail limits.
If Ppk is 1.0, the framework is creating 99.73% of its yield inside determinations. The bigger the Ppk, the less the variety between process yield and specifications.
If Ppk is in the vicinity of 0 and 1.0, not all procedure yield meets specifications.
If the framework is fixated on its objective value, Ppk ought to be utilized as a part of conjunction with the Pp index. In the event that the framework is focused on its objective esteem, Ppk and Pp will be equivalent. In the event that they are not equivalent, the littler the contrast between these records, the more focused the procedure is.
