In an honest, well-functioning org, those are decisions made by completely different groups that do not (and should not) report to each other. It's actually kind of depressing that we (and I include myself in that) assume otherwise by default.
I'm no longer in that industry, but as I recall there are actually rules imposing independence from investment banking and research arms, for example. Dates back to the Dot Com era where research analysts were touting IPOs for the investment banking division.
In this case, both decisions are weighty enough that they should be made at the very top, by the same people.

I don't agree at all. Different groups should be supporting each other and the overall bottom line instead of their parochial, narrow self-interests - the latter is a poorly functioning org.
If by group A delaying its $100M cost-cutting, group B can add $1B to the bottom line, it would be a corporate and group management failure for group A not to cooperate.
I have bad news: most large corporations are successful because they know how to make money. Often, the internal operations, are disappointingly bad, just not bad enough to kill the corp fast.
