A Brief Guide To Learn About Six Sigma
Six Sigma DMAIC Model
Six Sigma DMAIC model is the backbone of the whole initiative, mostly known as DMAIC project methodology. The DMAIC Model stands for: Define, Measure, Analyze, Improve, and Control of the processes and the system under a Six Sigma initiative. Beware that some authors like [Harry and Schroeder, 2000] identify not 5 but 8 stages as part of the core process of Six Sigma. They add Recognize prior to Define and Standarize, and Integrate after the Control stage.
For the sake of simplicity we’ll stick with DMAIC in the “standard” form.
- Define: The problem to be solved with proper prioritization is written down, and the according goals should be set.
- Measure: The process affected by the problem is “understood” and data gathering, assumptions and process capability are determined.
- Analyze: The causes or effects for underperforming are identified and possible solutions arise.
- Improve: The best options are picked up in order to be implemented and go through detailed scanning in order to check for desired performance.
- Control: Process control methods and perfomance monitoring are implemented in order to sustain the solution.
A simple method to achieve extraordinary results, so they say. Simple, but not easy. The practice has proved that the implementation of such a method is far from easy. It requires trained professionals and strong leadership to help change the organization’s culture and status quo.
