I think the way you framed that is bang on.
Shipbuilding in particular and a lot of aspects of procurement are essentially a series of trade-offs in order to make the least bad decisions, not ones that are inherently perfect, and that stretches across the entire continuum, including things like deciding who is going to be the prime contractor. There are lots of different models suggested, and there are two different considerations, with pluses and minuses involved in all of them.
To go back to some of my opening comments, one thing we've consistently seen is that we tend to sacrifice schedule and speed of delivery to satisfy other considerations, whatever they may be. We need to think about ways in which we can put more emphasis on sticking to a schedule, because it has knock-on implications for a lot of other things like capability, affordability and so on. As well, there are ways we can look at to make more investments up front in human or physical infrastructure or other things we've already talked about that could potentially accelerate those schedules.
I think we've unfortunately too often been penny-wise and pound foolish. We are in this, and if we want to see it successfully delivered, then as a country we should be looking to making national-level decisions to have this program of work move forward as expeditiously as we can make it.
