I would get Public Works out of defence procurement, put all the responsibility on the defence minister, perhaps have a subcommittee of this committee to specialize on oversight of defence procurement, and then insist that the minister is responsible for questioning every single statement of operational requirements. That's where the generals will try to Canadianize, and that's where the discipline needs to be exercised. If you do that, you streamline it and you move forward.
The other point, and I've already made it, is do not make these things too complicated. Buy proven off-the-shelf designs or equipment.
