I've also worked in an "insane scale" plant and totally relate. I've been in two facilities where it took over 5 weeks to get product through from start to finish. One made big things, one made small things. Literal square footage to store stuff is sometimes the reason you cannot produce more stuff. Some items have 2 month lead times, which really slows down the ability to move fast. I think most people could look at one aspect and determine a fix for when that isn't working well, but it takes much more to understand how the whole system reacts and how to keep production going reasonably well.
