So you are telling me, your AI code passes a six sigma grade of quality control?
I have a bridge to sell you. No, Bridges!
It's even funnier when you consider that Toyota has learned how bad of an idea lean manufacturing/6-Sig/5S can be thanks to the pandemic - they're moving away from it in some degrees, now.
What Toyota realized in 2011 due to the Fukushima disaster however is that this completely fails for computer chips because the pipeline is too long. So they kept JIT for steel, plastic parts etc but for microcontrollers, power supply chips, etc they stockpile large quantities.
Six Sigma came out of Motorola, who still practice it today.
It was then adopted by the likes of GE, before finding its way into the automotive and many other manufacturing industries.
