We order 6,000 castings.
Our foundry orders enough material for 6,000 pours.
10:00am customer - "We now need only 1,000 rotors next week"
We roll back order to 1,000 castings.
Our foundry cuts back to enough material for 1,000 pours.
11:00am customer (in a panic) - "We need 10,000 rotors next week"
We franticly order 10,000 castings.
Our foundry says there is not a hop in hell of getting material for 10,000 pours since nobody is scrapping cars and they just can't get that much.
And then back down.
Back up

And this is one component of the thousands in a car!

I'm an engineer in the manufacturing industry-- this is exactly how it is. It's asinine how poor the communication is across the board and how disorganized manufacturing plants can be. The supply chain issues have only magnified these sorts of problems.
