Records have to be kept in sync.

If one dept deletes a record and the other doesn’t, how do you decide who’s right?

You could add a third dept that gives them both orders, but now that third dept is a single point of failure.

If I were a customer of two different companies for the sake of redundancy, wouldn't I have that same challenge? I could be my own point of failure.

Though, I suppose if I'm responsible for it, I fix it faster for myself.
