Six Sigma was famously started at Motorola in the 1980s by Mikel Harry and Bill Smith, two engineers who developed the methodology to improve operations on the manufacturing floor.

In the mid-1900s, Boeing, Ford, and Toyota began experimenting with Lean manufacturing, a process aimed at reducing waste while maximizing productivity in their plants.
