I think the mystery shopper service has been very powerful. May I say one thing about the mystery shopper? It is a very confusing name. If anyone of you is familiar with mystery shopping as a thing, it's not like that. We ask businesses of any size, but they are quite often small businesses, to come to us when they have a problem with public procurement, and then the team investigates. We don't have powers to turn that around and say, “You awarded this procurement to this guy, and actually you should have awarded it to these people”, but we learn lessons. We then have a sense of what's not working. That has enabled us to pinpoint the things that we really need to change, so I would say that's very powerful.
I think also that the target has helped to focus minds. Breaking the target down, putting a sub-target on each department, and requiring them to aim to meet that has been powerful.
