Yes, okay.
So you need flexibility in developing the project to adapt to the particular place you're looking at. We also know that you need to have new ideas and innovation. You cannot just do what you know has worked, because that's actually looking backwards all the time and not looking forwards in terms of what the needs might be for the future. So the challenges and the opportunities in relation to social finance, it seems to me, are very pertinent issues—the implementation and evaluation of projects—and there's a big tension between wanting to do something you know has worked and something that is new and innovative. This seems to me to be quite a problem for the area of social finance that focuses a lot on innovation.
What you need to make sure is that, if you do have innovative projects as well as tested and tried ones, you evaluate them well and you go beyond just a pilot. There is a lot of experience from the project in which I was involved in Britain at the end of the 1960s, beginning of the 1970s, which produced very successful findings, very similar to the Peterborough project in the U.K. But when an attempt was made to replicate it in other prisons, they did not get the same results. So there is always this problem that pilot projects tend to be more successful than projects that are scaled up, and I think that is an issue in this area.
So I think that in a sense, for the development of social finance, it's an area that has many histories in crime prevention. Public-private partnerships, corporate social responsibility, social responsibility are also aspects of work in which crime prevention has been very interested, and the National Crime Prevention Centre believed in the business of the private sector being involved in crime prevention right from the beginning. That is part of the international guidelines on crime prevention, that everybody in a community—private sector, business sector, civil society, NGOs, residents—all have a part to play, as well as institutions and services.
