I don't think it's as much about collecting data as it is about making the decision to do it. So I think the data can help, but I think as Dr. Russell said earlier, you can do some kind of an analysis with existing data. It may then suggest new data that you need, but I would do the analysis first, rather than to wait for the data to come.
In terms of the most effective first steps, who you should hear from? Quite frankly, I would talk to the budget officers in the finance bureau and ask them, “What would you need to do this? Do you need more training? Do you need more information? Do you need to visit other countries' ministries of treasury to see what they've done?”
Again, from a public administration viewpoint, which is my area, if they're going to do it, they need to know how to do it. They need to be able to do it.
So I think that's where I would begin.
