@lighth0se33 – That makes good sense. I have no idea whether those companies use flexible manufacturing, either, but I do know that Toyota does, and they were one of the first to use it.
My husband works at a Toyota factory, and he frequently uses machines for several different purposes. He just has to change a few settings and move a few things around, but at least he doesn't have to have a totally different machine for everything he needs to do.
Toyota must be doing something right, because my husband has plenty of work to do, and he gets paid good money for doing it. I'm pretty sure the flexible manufacturing system is a part of why the business is doing so well.
