You have to start by understanding what the objectives of the law are and the steps you're going to have to go through to get there. Once you have an idea of how the law is supposed to work, then you need to develop some sort of performance framework. This pertains to what it is important that the law accomplish, how it helps people and whether it is going to be timely. Then you start looking at things like performance indicators and collecting the data that suggests this.
This sounds very theoretical, but what you need to know is how much time it is going to take to investigate each of these cases. Is it a reasonable amount of time? Is the investigation being conducted satisfactorily? Are the whistle-blowers who go through the system happy with the way they are treated and the resolution they get at the end?
It's the same for the people who are accused of the wrongdoing. You would like to know what the baseline of the wrongdoing that people observed when the program started was and how it has changed over time. Right now, none of these questions are being asked. Everybody in government can say, we have a law and it works fine, and there's no way to contradict them really.
