I'll just add that we have opportunities for relatively direct feedback from our main customers and clients on a weekly basis.
More seriously, there's a set of objectives that are agreed on as we go forward, in terms of our advice. We're not in the business of programming. We don't measure our service to Canadians, and in that way it is a service that is internal to the government and the Prime Minister.
But in terms of supporting the Prime Minister in his role, and in terms of supporting the clerk in his role, as head of the public service, as Michelle said, we measure, to the extent we can, and we seek feedback on a regular basis. We're pretty hard on ourselves as well, in terms of assessing.
Having said that, the last couple of years have provided other opportunities to look very hard at what we do. With the nature of the budget changes that we've been living through, that are being reported, and that we're speaking about here, we have had to step back and ask some hard questions about what we do and why we do it.
So we are different from other departments in our ability to conduct evaluations of the normal course of a program or things like that, but I can assure you we have opportunity to get feedback and to assess how well we are doing in playing that role.
