DMAIC (Define, Measure, Analyze, Improve, Control) is really a Six Sigma method used to improve the existing business processes. A companion methodology, DMADV, is used when new processes are created or implemented. DMAIC is a technique or tool put in place by having an objective of continuous improvement in mind, working towards a goal of business process excellence.
the Background – Both DMAIC and DMADV use a common ancestor in Deming’s Plan-do-Check-Act Cycle, according to the Japanese quality improvement methods which Deming studied and helped implement in the years after the second world war, and at last introduced to the united states. DMAIC is the will of Motorola, first introduced almost 30 years ago.
As an ongoing improvement tool, DMAIC combines the characteristics of two methods, Lean and Six Sigma. Where steps towards improvement rely on implementing statistical control, Lean, and Six Sigma alone cannot always readily implement improvement. A combination of the two methods however, as incorporated into DMAIC, ends in a strong tool for continuous improvement.
You can find 5 phases to the DMAIC method: Define – An improvement initiative (or possibly a problem requiring resolution) is identified and scoped with this phase. The nature of the problem or improvement is described together with any supportive data or information that will lead to what is still an unknown solution. Simply the perfect solution is, typically, will not be found came in just a step, but only after an incremental development of the actions have occurred. Measure – a data baseline is made to identify the important aspects of this process, in addition to relevant data. The measurement of the parameters that are established, therefore, that the end result could be significantly in comparison with, or measured against their original conditions. Parse – the Expected result of the analysis, statistics and data analysis carried out in this phase. Any part of focus will probably be on determining those parameters which best describes the cause consequence relations, and we hope to get of the causes, where there are problems. Improve – in this phase, the standards which are believed to bring about enhancing the current process, considering the analysis made, will be suffering from further testing. Pilot programs may be instituted occasionally to validate the improvements that have been observed to occur. Control – in this final phase, before the process is repeated, improvements that have occurred will be documented, and implementation plans and change management plans will likely be applied as needed. Control is vital to ensure that any deviations from the target result are corrected on a regular basis.
