Specifically on complaints, I guess the ROI is based on the statute and the regulations. The return on investment is to ensure fairness for them. It can be by way of compensation.
For mediation, it's also an expedient and cost-effective alternative to litigation, so there's a significant ROI there. While I can't quantify it, I can certainly say that those who have participated in litigation will extol the virtues of a one-day mediation process that leads to a mutual consensus resolution of the issues.
The ROI that's harder to quantify is on the systemic reviews in which we make recommendations to departments. Again, the point there is that we're talking about $37 billion of transactions, so whether the recommendations are around transparency or efficiency, the goals are always to make the process more efficient and simplify the process. While I can't quantify the ROI specific to procurement practice reviews, I would say that it is substantial.
