• Date: November 04, 2009

Six Sigma is a set of concepts and methodologies that aims at achieving perfect business processes wherein the total number of defects never exceeds 3.4 per million opportunities that exists for such defects to occur. Six sigma uses a wide variety of statistical tools and techniques some of them being control charts, defect measurements matrices, pareto diagram, process mapping, SPC, FMEA etc.

Six Sigma relies on two key methodologies viz; DMAIC (Design, Measure, Analyze, Improve and Control) and DMADV (Design, Measure, Analyze, Design and Verify) for making necessary improvements in business processes.
