Lean Six Sigma's Evolution

Abstract:When Motorola deployed its initial Six Sigma system in 1987 there was none of the infrastructure and focused training associated with modern Six Sigma practices. Six Sigma use expanded when Allied Signal and General Electric deployed Six Sigma with the intent of improving financial performance rather than quality.

To me, you can't review the basics too often. It's most always the basics that trip you up.
