Different aspects of Six Sigma definition:

• Technical - Six Sigma defined technically refers to achieving a performance level that is 6σ rated or producing no more than 3.4 defects per million opportunities.  
• Methodology - The six sigma strategy follows one of two methodologies: DMAIC or DMADV.  Both DMAIC and DMADV are the steps that a six sigma practitioner are expected to follow throughout their improvement projects.
• Philosophical - The philosophical outlook of six sigma is continuous improvement.  This perspective is that any and all processes can be improved by following the DMAIC method: Define, Measure, Analyze, Improve and Control.  Every process has one or more inputs (x's) and is aimed at producing a targeted output (Y).  This tells us that if we control inputs we can stabilize and control outputs which result in consistent and improved processes.  The formula used in six sigma is expressed either as Y=F(X) or Y=F(X)+ε.
