There are probably a few points here. The first one I'll start with is, it requires our attention. Just from a pure bandwidth...a very dynamic environment, and you need a certain DM-level engagement every week, and when you're involved in intense periods, almost daily. To try to time-slice that into everything the large organization already has—just pure bandwidth—you end up with a challenge. That's one reason.
The other reason that this works is having a built-to-purpose organization. You want people who really understand this business up through the most senior levels involved in making the decisions. You may not get that in another model and having that procurement authority shared there. There are times we get involved, and while we're making C-level decisions, we're also having to discuss bits and bytes because they directly tie into how the performance of that procurement is going to be conducted. I would dread the idea of trying to do this without the procurement authority.
