I guess my answer would be that it's probably both. There's good governance over decisions made as you reach junctures, making sure that you've thought of all of the possibilities before you move to the next stage. That doesn't necessarily need to have a lot of expertise externally. There is a lot of great expertise from an IT front within the federal public service. It's about tapping into that.
I think it's having the right mixture and knowing when you need that external independent overview and when you need to tackle independent oversight outside of the department who's the lead or the procurement arm. You can accomplish it both ways.
