My answer is quite simple, I think. The question that I think you should look towards is this: did the innovation alter the basis for making a budgetary decision?
It seems to me a good budgetary process means that the right information is brought to bear at the right time, to the right decision-makers. That doesn't mean any specific outcome is going to happen. It could be that people decide, “Oh well, things are inequitable, and we're comfortable with that.” I would hope not, but that's possible.
I think the point is that the process should allow for consideration of the right decision. I would say that you know you've gotten there when there is a sense that the innovation of gender budgeting has had an impact on the process of consideration.
