Definition - What is Six Sigma?
Six Sigma demands near-perfection with only 3.4 defects per million opportunities - at Three Sigma level, that same pharmacy would have 66,807 defects instead. General Electric saw $300 million increased revenue in first year, while US Army saved over $2 billion in 2007. Implementation uses DMAIC methodology: Define, Measure, Analyze, Improve, Control - but 60% of projects fail without process enforcement.
