Supports multiple frameworks but needs to improve Middle Eastern presence
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. It would be great if we could select multiple models within one project. Also, having better data filtering options would be useful. It would save a lot of time if the architecture diagrams could update automatically whenever the data changes instead of being updated manually every time.

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

"The most valuable feature is that it has a customizable meta-model, which is key."
"You can design using a diagram tool installed on your desktop, a key difference from other vendors."
"The most valuable feature is the traceability, you can trace any object to the other."
"There are a lot of different features, but the business/decision-maker feature, visibility, and dashboards are most valuable."
"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."
"There are plenty of features available such as the ability to test applications for issues and a user-friendly dashboard."
"If you face new challenges or issues then you can dynamically customize according to the business needs."
"The product is easy to use and well-structured for the integrations we need it to make."
"The solution is pretty stable."
"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."
"We have seen ROI with this solution over the years that we have used it."
 

Cons

"Having more control over page size is lacking in this product. Print utilization also needs to be improved."
"They should take more initiative to implement things that competing products have already come out with."
"If they want to expand in the European market then they are going to have to improve their technical support."
"The usability of the tool is an area with shortcomings that need improvement."
"The reporting could be easier to configure."
"It is vastly scalable but you can't run it on a Mac or Linux so it has limitations."
"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."
"While Avolution ABACUS is flexible, it can be complex to work with as it requires knowledge of specific configurations to customize the product."
"The solution needs to better integrate with other products, like Microsoft."
"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."
"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."
 

Pricing and Cost Advice

"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."
"The solution's pricing is not an issue."
"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."
"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."
"The cost of Avolution ABACUS is reasonable, given the features they offer in comparison to other tools."
"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."
