IT/Business Architect at a financial services firm with 51-200 employees4.0No summary available
IT/Business Architect at a financial services firm with 51-200 employees4.0I found the solution stable and excellent for meta-model customization during an ERC implementation. However, poor integration with other products and a lack of support limited its experimental use, leading management to discontinue it.
Enterprise Architecture Specialist at a energy/utilities company with 10,001+ employees2.5I use this for enterprise architecture modeling and value its modeling, but I'm unhappy with features, integration, and support. Lack of vendor investment means I'm looking to replace it, despite past ROI.
Database Administrator at a tech services company with 10,001+ employees3.5I've used this stable, scalable solution for modeling, appreciating its good UI and support. While initial setup was easy, I need better deployment guidance and more advanced modeling, including AI, to improve my 7/10 experience.
Enterprise Architect at a tech company with 501-1,000 employees4.5I find this product highly valuable for strategic planning, supporting various frameworks and heterogeneous models. Its ROI is high, setup was straightforward, and customer service is great. The only drawback is some UI navigation issues.
