Six Sigma’s approach is disciplined and data-driven in nature. This helps in mitigating variation in any process – right from manufacturing to accounting and finance – and thus eliminates any defects which might exist otherwise. The aim is to be as close to perfection as possible (3.4 defects/million opportunities). Processes are improved and variations are reduced by applying Six Sigma Improvement Projects, which are done by following either of the two methods – DMAIC (Define, Measure, Analyze, Improve, and Control) or DMADV (Define, Measure, Analyze, Design, and Verify). Professionals with Six Sigma Green Belt Certification are key players in executing Six Sigma Improvement Projects.
