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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It's more than just an enterprise architecture tool as it has a lot of nice features, e.g. messaging, simulation, etc."
"You can design using a diagram tool installed on your desktop, a key difference from other vendors."
"There are plenty of features available such as the ability to test applications for issues and a user-friendly dashboard."
"The product is easy to use and well-structured for the integrations we need it to make."
"The most valuable feature is the traceability, you can trace any object to the other."
"The ease of modeling and the ease of showing interconnectivity and relationships is the most valuable. It is fairly simple and out of the box. It is customizable in many ways. It is a pretty good tool."
"Avolution ABACUS allows for flexible enterprise architecture analysis."
"The most valuable feature is that it has a customizable meta-model, which is key."
"There are a lot of features I find valuable, but I think that the metamodel customization is one of the best features that the solution offers."
"The user interface is good. It's both clear and comprehensible. It's easy to work with."
"The solution is pretty stable."
"We have seen ROI with this solution over the years that we have used it."
 

Cons

"It doesn't have the simulation capability, which would be helpful in doing some business process analysis and improvements."
"While this is one of the most powerful tools on the market it does not integrate well with Microsoft Office or others."
"Avolution ABACUS has the drawback of needing data filtering at the development level, unlike some tools that offer filtering at deployment. Two areas where Avolution ABACUS could be improved are regional support and flexibility in model selection. Sometimes, it's challenging to access support or updates in certain regions, which can slow down progress. Additionally, it would be beneficial if the tool allowed more flexibility in selecting multiple models within a single unit."
"The usability of the tool is an area with shortcomings that need improvement."
"In the future, there could be improvements in integration and enhancements."
"I use reference models, which are taxonomies, in my EA work. It is a reference model/taxonomy of things with capabilities, sub capabilities, and sub-sub capabilities, so you're working it down. I haven't yet found a simple way to implement that in Abacus. It could be that it is there, but I don't know how to do it."
"They should take more initiative to implement things that competing products have already come out with."
"The most valuable features are the catalog and the diagram."
"There needs to be more information at the outset about how to use the solution and how to deploy it. The deployment process needs improvement."
"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."
"This solution can be more user-friendly and easier to use, with better dashboards."
"The solution needs to better integrate with other products, like Microsoft."
 

Pricing and Cost Advice

"The cost of Avolution ABACUS is reasonable, given the features they offer in comparison to other tools."
"This solution is expensive for some people's budgets and they need to offer a Lite version at a cheaper price"
"My company makes annual payments toward the licensing costs of the solution. Considering the product's capabilities, its prices are very reasonable."
"I'm paying on a yearly basis. I don't know whether it's a highly expensive tool or not. I'm getting a single version of it, and I don't have the enterprise part on it because I don't need the server component, and I don't need a web browser component. My estimate would be that it's a very reasonably priced tool given that you don't need to have licenses with everyone in order to get the information and the decision support capabilities out of the tool. You use the enterprise edition on top of the studio, which is the heart of the tool. I am not aware of any additional costs."
"The pricing is quite good compared to the competition and it is part of the reason we chose the product."
"The solution's pricing is not an issue."
"It is expensive."
"To get a fairly extensive license for Enterprise Architects from Spark is approximately US $400.00, maybe less, but with Avolution Abacus it was approximately US $2000.00 per year, and that includes maintenance with the Abacus tool."
