Similar to what I said a while ago, it's not so much how many procurement organizations there are; it's how well they work together. Whether there are four or one, it depends on what kinds of powers you give them and what kinds of resources you give them to make sure the processes go quickly and effectively.
I think that right now we tend to go towards the fact that there is duplication or that there might be inefficiencies built into the four-group model, but that could be resolved within this model or within another model. It's a question of creating that political oversight, giving a little bit of room to breathe to some of these public servants who are risk averse because they feel that they need to be risk averse. There are a variety of solutions going forward, and I'm not going to suggest that there's one that's better than the others.
