  • Hi Terrence!
    Yes, DMAIC is based on the Scientific Method. That means you Define a problem, Measure how bad it is, Analyze the root causes of the problem, develop countermeasures to Improve the process and then Control the process to maintain the gains. And you’re right that DMAIC is used for existing processes. There are other methods that are right for designing brand new processes. I hope that helps!
