In terms of what could be improved, we did not take the whole package with all the modules, and I think that the integration with other platforms like Office could be better. The reverse engineering of the database is already there, but in the next release I would like to see some pilot supplied with the solution in order to address any database.

I didn't use the solution for very long, so it's hard to go too in-depth with what the solution may have been lacking. In the commercial approach, a lot of implication is on the technical. I wasn't really well supported when I was using it, which made it difficult. The integration with all other modules could be a bit better. If you want make it a universal solution, you have to add some items, and find the modules you need. That's not too helpful for clients. They need to have a package that can satisfy clients fully on every project. The solution needs to better integrate with other products, like Microsoft.

I find that almost every feature related to the models requires improvement. For example, I would like to see more trendy models, the look and feel of the models can be improved. This solution can be more user-friendly and easier to use, with better dashboards. The impact analysis feature is in need of heavy improvement. The is a standalone product that lacks integration with a business process automation engine. I would like to see the workflow improved, where it integrates seamlessly with the artifacts.
