The most useful thing about this software tool for me has been its ability to create diagrams that clearly show how different systems interact with each other, which in turn helps us understand our system better. I have used it only once so far but am looking forward to using it again when we need more detailed information about our system. It's not something i dislike at all - it just doesn't do much for me apart from creating some nice diagrams. Try out their demos and see if you like them. We are trying to build an ERP solution that will help track inventory across multiple locations and provide real time data to sales people. This product helped us visualize what was happening within our system.
