Question

John is a newly minted quality engineer at MakeStuff Inc. His boss tells him to increase the process capability index of their main product. John is somewhat lazy and does not want to tackle the variation in the process, so he decides to simply increase the upper specification limit and reduce the lower specification limit. Does this increase the process capability index?

Answer 1

Answer:

Yes, it does, though one might question if the underlying process is really better.

Explanation:

Process capability index is a statistical measure which determine the output with specification limits, in the above case increasing the increasing the upper specification limit reduces the lower specification limit as it produces the ability of output.
