It goes on continually under their 6-Sigma program. It's amazing the kinds of things that are institutionalized (we always did it that way) and can be removed or replaced. Look for a company with an active QC or 6-Sigma program.
Six Sigma is a Ponzi scheme. I have never experienced this being implemented correctly. It always seems to end up with some muppet whose sole purpose in life is to convince the management that he should remain on a ridiculous salary or even employed.
One bloke I had to work with, who was a 6 Sigma ninja warrior, said that he had improved the efficiency of production of a particular product by reducing the amount of distance it had to travel around the building. He said he had reduced it to something like 24 metres. The product had to go from one side of the building to the other (goods in to goods out), absolute minimum distance. The building was over 100 metres long. Before his intervention it left the building at the same end that it arrived at.
All the while, the rest of the manufacturing process was not made any more efficient.
Another Six Sigma nutcase at another company said it would be more efficient if we cease production for six months while we dig up the floor and fit a complicated conveyor belt type thing on rails to move around some military trucks on an assembly line, where the trucks arrive driveable and leave driveable. They are at no point in their assembly, not driveable. You can just drive them around the building. But nope, this is more efficient.
Anyway... OP, be mindful that people don't like to be proven wrong. I have tried to go to CEOs and others with hard evidence, scientific facts etc. pertaining to why something won't work or isn't more efficient... They mostly don't want to know. I've even been told by a CEO that I don't know what I'm talking about when it comes to a mains transformer because my job is to design electronics not to manage the site facilities.
