ABSTRACT
The first entities attributed with blending Lean and Six Sigma were AlliedSignal and Maytag, independently in 1999. At that time, it was referred to as “Lean and Six,” as both AlliedSignal and Maytag realized that the two methodologies complement one another. It was not until several years later that the term Lean Six Sigma became popular and only since 2004 that being certified as the Leader Practitioner gained recognition as a solid industry certification.
