In terms of strengthening the process, I think we've already put in place a number of measures. I think, as we've indicated in terms of having champions and ensuring that as part of initiatives coming forward, we can build on that. I think in the last two years we've moved the yardstick, so I think that's progress. Certainly I think to make that process more robust, embedding it in terms of not losing sight of it by having the champions' network and the interdepartmental committee is very important.
In terms of past policies, I'll let Mr. Wild speak to that, because it's trying to get at the issue of the A base. It shouldn't just be focused on incrementality, but I think the whole issue of doing strategic reviews is trying to look at effectiveness and impacts. I think the whole role of program evaluation in government is looking at the effectiveness of programs and what impacts programs are having. Are they having unintended consequences or negative consequences on men or women or employment equity groups or the disabled? That should certainly be a role, that program evaluation is a management tool to make our programs better and more responsive on some kind of evidence base.
