Different programs have different objectives, so it would have to be based on a particular program's objectives. If you talk about, for example, accelerators or those sorts of things, the questions would be how many businesses have you started, how much have they grown, and how many markets are they in?
It's about trying to find things you can quantify. Consider the SR and ED program. Broadly speaking, Canadian R and D has been falling over the last 15 years. I'd say that's a starting point; it's probably not being very effective at driving R and D.
I think it would have to be driven by the purpose of the program.
