This is part of the Six Sigma methodology, but it also is often used as a stand-alone method. DMAIC (an abbreviation for Define, Measure, Analyze, Improve and Control) refers to a data-driven improvement cycle used for improving, optimizing and stabilizing business processes and designs. It and can be used as the framework for improvement projects outside of Six Sigma.
The framework is described briefly here:
Define – who are the customers and what are their needs. Define the project purpose and scope. Define the current process and what customer wants from it.
Measure – how is the process performing and how is it measured. Gather data on how well the current process performs in meeting customer needs
Analyze – what are the most important causes of problems. Identify root causes of performance gaps and confirm with data.
Improve- how do we remove the causes of problems? Plan, test, and implement solutions that eliminate root causes (use data to evaluate both the solutions and plans used to carry them out).
Control – how can we maintain the improvements? Maintain the gains by standardizing work methods or processes. Anticipate future improvements and preserve the lessons from this effort.
