DMAIC
The DMAIC process is a core component of the Six Sigma methodology. It is used when making improvements to an existing process.,(For creation of new processes and products, the DMADV framework is followed.)
Walter A. Shewart, in the 1920's. Suggested the well-known Plan, Do, Check and Act (PDCA) cycle for improvement. Even though DMAIC is not the same then these methods, it incorporates both approaches. DMAIC emphases on using data to make decisions and then verifying those decisions before committing business resources.
The advantages of the DMAIC process is not the top-level phases but what is contained in each phase. The contents provide a common, structured approach to problem solving. For each and every phase, there are some major activities and an associated overall question to answer.
Six Sigma-DMAIC is an abbreviation for the five key phases in a process improvement project: Define, Measure, Analyze, Improve, and Control.
Phases of DMAIC consists of a set of tools, techniques, and deliverables. In many Six Sigma books, DMAIC was shown in the context of Kaizen and Lean teams. In previous years Improvement Process, DMAIC is one of a variety of proposed methodologies. Professionals apply scientific methods based on observations, formulate a hypothesis, collect data and form a conclusion.
When to use DMAIC?
- We use DMAIC for root cause analysis
- There is, a problem and causes are unknown
- The stakes are high, and we need to be sure the solution fixes the problems
- A problem exists, solutions have been tried, but root cause is still unknown
