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 a good product with a complete set of templates, frameworks, and notations."
"It's more than just an enterprise architecture tool as it has a lot of nice features, e.g. messaging, simulation, etc."
"There are a lot of different features, but the business/decision-maker feature, visibility, and dashboards are most valuable."
"Avolution ABACUS allows for flexible enterprise architecture analysis."
"ABACUS is a really forward thinking product with a lot of nice features in it; it's not just all talk, it actually works."
"The most valuable feature is the traceability, you can trace any object to the other."
"If you face new challenges or issues then you can dynamically customize according to the business needs."
"It is a very stable solution...The initial setup of Avolution ABACUS is very easy."
"The main advantage of the solution and its most valuable aspect is the customization of the meta-model."
"The user interface is good. It's both clear and comprehensible. It's easy to work with."
"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 solution is pretty stable."
"The System Architect Product has greatly assisted the corporate strategic planning process in two areas: the simulation of scenarios for Enterprise Transformation Projects and providing a global view of Enterprise Capabilities and Functional Gaps."
"We have seen ROI with this solution over the years that we have used it."
 

Cons

"The usability of the tool is an area with shortcomings that need improvement."
"If they want to expand in the European market then they are going to have to improve their technical support."
"While this is one of the most powerful tools on the market it does not integrate well with Microsoft Office or others."
"It doesn't have the simulation capability, which would be helpful in doing some business process analysis and improvements."
"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 company needs to update the UML version they are using for the product as it is quite old."
"Based on my experience, this is not a product that I recommend at the moment."
"In the future, there could be improvements in integration and enhancements."
"The solution needs to better integrate with other products, like Microsoft."
"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."
"Some aspects of the user interface lack a common navigational or functional framework."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
"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."
"This solution can be more user-friendly and easier to use, with better dashboards."
"It was sold separately and it is not very easy for somebody who wants to use the solution for modeling to think that you have to select specific modules in order to use the product."
"We are not happy with this product and are not planning to continue with it."
 

Pricing and Cost Advice

"The cost of Avolution ABACUS is reasonable, given the features they offer in comparison to other tools."
"The pricing is quite good compared to the competition and it is part of the reason we chose the product."
"There is a subscription for this solution. We are on an annual subscription because you sometimes receive special offers the longer you subscribe."
"This solution is expensive for some people's budgets and they need to offer a Lite version at a cheaper price"
"It is competitive. It is not chump change. I am just using the studio version. I am not using the full enterprise version, which would probably cost me three times more for single-use, but it gives a lot more capability and analysis. It is server-based as well, and it is reasonably priced compared to a lot of the other tools. There are other tools that have other sorts of capabilities, but in order to use them, you'd really have to have like 50 users for the price to become justifiable."
"My company makes annual payments toward the licensing costs of the solution. Considering the product's capabilities, its prices are very reasonable."
"It is expensive."
"The solution's pricing is not an issue."
