I think I will start, and Glenn will absolutely add to it.
My comments will be more high level, about having a horizontal initiative across the government, and what I have seen over the last couple of years, which is that when there is a horizontal initiative, you need one department or one deputy minister to be accountable for achieving that, and that deputy needs to have the ability to compel other deputies to do the jobs they need to do in order to support the achievement of outcomes. All too often, when we look at horizontal initiatives, we see exactly that as the reason they don't achieve the outcomes they want. That is, no one feels they can compel other departments, and no one really feels like they are the lead.
If the government goes that way, or if your report makes that recommendation, I would still make it clear there needs to be an accountable party.
