DMAIC (Six Sigma Problem Solving)
DMAIC is an acronym for Define, Measure, Analyze, Improve, Control. It provides a systematic way to approach a problem. Using the DMAIC methodology to structure a problem-solving effort helps prevent skipping steps, which can lead to poor solutions.
While is seems foreign at first, when you look more closely at it, the DMAIC methodology follows a logical flow. In fact, there is a good chance you already follow these steps when solving problems on your own. You probably come up with some sort of problem definition, research the problem, dive into the details, and then come up with a solution. DMAIC simply formalizes what you already know.
DMAIC is an acronym for problem solving in the Six Sigma process. The pronunciation is Duh-May-Ick.
While Six Sigma = DMAIC for many people, there is another improvement method that also uses DMAIC: Lean.
The kaizen process follows nearly the same steps as the DMAIC methodology, though it refers to them differently. “Define” matches the chartering process. A process walk with data collection is essentially the “Measure” step, and so on.
Other problem-solving methods have similar approaches as well. The 8D process, for example, also very closely parallels the DMAIC methodology.
These problem-solving methodologies are similar for a reason. It is because there is a logical progression to problem solving. Effective methods latch onto that flow and end up being very similar when looked at from the 30,000-foot view. The differences tend to lie in the details rather than the broad-brush strokes.

Great info. Do you have an example of this tool in action?
Thanks,
Jeff

Sorry, nothing immediately available that I can post, but I’ll try to link to a few book titles in the next few days that have some case studies.
