We've seen ROI with erwin. It's been successful. My boss is the CIO and he is quite pleased with it. In fact, a couple of years the CEO mentioned it in one of his newsletters. It's used widely and has acceptance within our company. It is a good way to see all the pieces within our company. ROI is a tricky thing. Did we make any money out of it? No. It's a cost. But it is part of the fabric of the company now and people know that they can see their systems in there and they can look at their data and can understand what's going on.

It's really hard to measure a return on investment for this kind of solution, but I think we have seen ROI because it's helped us to secure our SAP project.
