I'll start, and then I'll get Brian to reply, because he has more of an institutional memory on this from Treasury Board's perspective.
I see that the reliance on supplementary estimates (A) and (B), as an example, will be less than it is right now. As you sequence the main estimates after the budget, the main estimates I think will take on a more important role, as they ought to, but this will take time. Again, some of the changes to operationalize within government will take at least a couple of budget cycles to get it closer to the full potential.
Brian, would you like to continue?
