There used to be a Lego plant a couple towns over when I was a kid, employed a lot of people before it closed. It was always funny talking to kids that’s parents worked there because they acted like they were in the CIA. I guess they all had to sign NDAs, so they were extremely tight lipped about their jobs.
Anyway, I am pretty sure Lego is the only company that has actually achieved 6 sigma… probably before it ever even became a thing.
