The Tesla Team Solving a Problem That Didn't Exist

So before optimizing your process, start asking yourself, do we need this process? And then ask yourself, why do we need this process? I was reading the book of Elon and he told me in the book that there was a whole division working on some safety issue, some fire safety safety issue. But the division was thinking it was working on noise reduction. So they were talking later when Elon find out found out they were talking to the noise reduction company and the division and the noise reduction division thought, okay, yeah, but it's a safety for fire, a fire safety thing.
