The DMAIC Methodology
DMAIC stands for Define, Measure, Analyze, Improve, and Control. The Define phase requires the definition of specific customer requirements, project goals, and the system itself. The Measure phase requires the collection of relevant data in order to measure the present process. The Analyze phase investigates and verifies the data for cause-and-effect relationships. It tries to find the root cause of every defect discovered. The Improve phase, on the other hand, optimizes the present process by using techniques and standard work for future state process. The Control phase ensures corrections to any deviations from the standard before such deviations can cause defects. It implements control systems and monitors the process continuously. The DMADV Methodology DMADV stands for Define, Measure, Analyze, Design, and Verify. The Define phase defines the goals of the design based on the business strategy and customer specifications. The Measure phase identifies the critical characteristics of quality. It measures risks, process capability of production, and product capabilities. The Analyze phase includes analysis in order to create and design alternatives while the Design phase chooses the best alternative from the previous phase and improves on it. Lastly, the Verify phase implements the process, sets up pilot runs, and turns it over to the process owners. Important Six Sigma Roles The Executive Leadership consists of the organization’s top management. These people create the vision for the implementation of Six Sigma.
