Great taxonomy support but raw business processing should be upgraded
Alfabet is not just a technology tool, it's also a business tool. And if a decision's made without the business involved, then Alfabet will not be in a position to deliver anything more than support for enterprise architect drawings and solutions drawings. It has to be the business. If you do that, it works well. If you don't and I've had the experience where they haven't evolved a business, then it just becomes a tech tool that the business doesn't care about. The stigma of having an environment that was so delayed in the maintenance caused lots of finger-pointing within the organization of who was right and who was wrong. It took a considerable period of time to move people past that point to actually look at it as a business tool supported by the technology team. I rate the solution seven out of 10.

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.

Cons

"The user experience, the layout and the different technologies behind the presentations are a bit old."

"IT governance in this solution needs improvement. We would like to see the visualization of assets, as well as artificial intelligence techniques to assist us in making our decisions."

"There needs to be more information at the outset about how to use the solution and how to deploy it."
"Some aspects of the user interface lack a common navigational or functional framework."
"We are not happy with this product and are not planning to continue with it."

How to export IBM Rational System Architect data into Alfabet Enterprise Architecture Management (by Software AG)?
Hi @BruceLang ​ If I recall correctly you can export System Architect data via an XML file, and Alfabet will import XML. However, as you know these two products are very different in what they do and how they work. So depending on how you have used System Architect you are likely to be dropping a lot of information, you may be able to bring more information if you are planning to use ARIS as we...

Hi @BruceLang ​ If I recall correctly you can export System Architect data via an XML file, and Alfabet will import XML. However, as you know these two products are very different in what they do and how they work. So depending on how you have used System Architect you are likely to be dropping a lot of information, you may be able to bring more information if you are planning to use ARIS as well as Alfabet. In any case you are still likely to have to do quite a bit of manual editing and changes to get the XML working.Kind Regards Mark
