Six Sigma Green Belt certification trains employees to analyze and solve quality problems using DMAIC and DMADV methodologies. Green Belts contribute to data collection, measurement, and analysis while continuing regular job responsibilities, supporting Black Belts in achieving 99.99966% defect-free results.
Most Six Sigma projects fail to meet objectives, making consultant choice critical. New consultants charge $1,000-2,000 daily while experienced professionals command $2,500-5,000 per day, with project fees ranging $20,000-100,000. Interview multiple candidates, check references with other business owners, and prioritize culture fit over credentials alone.
Six Sigma targets 3.4 defects per million opportunities, dating back to Motorola in the 1980s when executive Art Sundry sought better quality consistency, eventually winning the Malcolm Baldridge National Quality Award. Four main software types exist: analysis tools, program management tools, DMAIC/Lean collaboration tools, and data collection tools feeding information directly into analysis systems.
Lean focuses on seven deadly wastes (overproduction, waiting, transport, motion, over-processing, inventory, defects) to improve workflow and reduce cycle time, while Six Sigma uses DMAIC methodology to achieve 3.4 defects per million opportunities. Companies like General Electric, Motorola, and Bank of America saved millions implementing these methods.
DMAIC (Define, Measure, Analyze, Improve, Control) serves as the roadmap for implementing Six Sigma, helping businesses reduce variation and waste systematically. Originally called Six Steps to Six Sigma when Motorola developed it in the 1980s, over 60% of companies fail to achieve results when they stop properly implementing all five steps.
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.
