Question

Quizplus · Accepted Answer

The "Control" phase of DMAIC is intended to sustain the improvements achieved during the earlier phases. It involves establishing a monitoring system to ensure that the process remains stable and within the desired performance range. Therefore, the best choice is E, "improvements are sustained," as it directly addresses the goal of the Control phase. While A, D, and C may be components of the Control phase, they do not address the overarching goal of sustaining improvements. B, "variability reduction is pursued," is a key aspect of the Improve phase, not the Control phase.
