Six Sigma DMAIC – Control Stage

The Control Stage is the final step in Six Sigma’s DMAIC (Define, Measure, Analyze, Improve, Control) process. It is an essential phase that ensures process improvements’ sustainability and long-term success. In this stage, control plans, statistical tools such as Xbar-R Chart and U Chart, cost-benefit analysis, the impact of variation, and sampling frequency play a crucial role in maintaining the gains achieved during the previous stages.
