B)To create controlled experiments to analyze sources of variation
C)To be rigourous in following the DMAIC steps
D)To prevent an improved process from becoming highly variable again.

Question

Quizplus · Accepted Answer

The "control" step in the DMAIC process aims to prevent an improved process from becoming highly variable again by establishing monitoring and control mechanisms that will sustain the gains achieved in the previous steps. This involves creating a control plan that outlines the steps for maintaining process stability and controlling the sources of variation. Therefore, the best answer is D.
