We do that in a number of ways. Sometimes we will do direct follow-up reports. We will look at a report that was done in the past and we'll look at the recommendations that we made. The audit objective in that is to say that the department has made satisfactory progress or it has not made satisfactory progress.
Sometimes we will do a direct follow-up audit like that. Other times we will look at the same topic but maybe from a slightly different point of view. We will bring back the things we identified in the past to remind people of that, and to try to see if there's progress.
I think our world is different now. We've been in this business for quite a number of years. There are probably very few programs now that we haven't audited at least once. Just about everything we do now has some aspect of looking back at what we did. And it's not just what we did; we'll also look at what an internal audit group did. We will look at committee hearings. We'll look at a number of different sources, and evaluations within the department, to try to bring all of that information forward to say, “This is the history of what's happened in this program”, so that people understand all of that.
