GM
Lots of valuable features, especially the metamodel customization
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.

Effective lifecycle management improves with strong version control and deep integration needs
There is room for improvement in implementing features fully. The user interface is inconsistent and outdated. It appears that different departments or locations have implemented features differently, leading to inconsistency. There is a significant need for improved integration, particularly using OSLC for connecting with other tools like SAP ERP or ALM tools. The version control, while consistent, lacks flexibility regarding changes in CAD data and requires manual intervention for BOM management analysis.
