It's not scalable. It can't support BOM management if we have thousands of parts. That's one of the biggest limitations. Relationship management should support large data. 

The workflow engine also needs improvement. It should support complex workflows. There are things with patch management that should be better.

There are hundreds of other things that we logged with them but never got implemented.

The cloud version isn't very powerful, so it doesn't support parallel workflow. It just supports the serial flow.

The stability and technical support could also be improved.

The Oracle Agile PLM disaster recovery solution is complex, and there is a lot of manual work involved when switching to the DR site. I would expect better for the DR solution in future releases. 

It also needs improvement in application proactive monitoring and health check-up.
