DMAIC (Define, Measure, Analyze, Improve, Control) is really a Six Sigma method employed to improve existing business processes. A companion methodology, DMADV, is utilized when new processes are designed or implemented. DMAIC is a technique or tool put in place by having an objective of continuous improvement in your mind, working towards a goal of business process excellence.
Background – Both DMAIC and DMADV use a common ancestor in Deming’s Plan-Do-Check-Act Cycle, according to Japanese quality improvement methods which Deming studied and helped implement in the years following Wwii, and at last introduced to the us. DMAIC is the coming of Motorola, first introduced almost 30 years ago.
Like a continuous improvement tool, DMAIC combines the characteristics of two methods, Lean and Six Sigma. Where steps towards improvement rely on implementing statistical control, Lean falls short, and Six Sigma alone cannot always readily implement improvement. A combination of the two methods however, as incorporated into DMAIC, ends in a strong continuous improvement tool.
You can find 5 phases to the DMAIC method: Define – A marked improvement initiative (or possibly a problem requiring resolution) is identified and scoped with this phase. The nature in the problem or improvement is described together with any supportive data or information that will lead to what is still an unknown solution. Quite simply, the perfect solution is will usually not be found arrived in just one step, but only after an incremental compilation of steps has occurred. Measure – A data baseline is made, identifying key facets of the present process in addition to relevant data. Measurement parameters are established therefore the final result could be meaningfully in comparison with, or measured against, your initial conditions. Analyze – Expected outcomes analysis, and statistical data analysis are conducted on this phase. Some part of focus will probably be on determining those parameters which most closely describe cause a consequence relationships, and hopefully bring about root causes where problems exist. Improve – On this phase, the standards which have been believed to bring about enhancing the current process, considering the analysis made, will be suffering from further testing. Pilot programs might be instituted sometimes to further validate those improvements that were observed to occur. Control – Within this final phase, prior to process is repeated, improvements that have occurred is going to be documented, and implementation plans and change management plans will likely be applied as required. Control is vital to ensure any deviations in the target result are corrected regularly.
