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

"Scalable and stable tool for roadmapping and modeling, with a good dashboard, end-to-end impact analysis, and portfolio management."
"There are plenty of features available such as the ability to test applications for issues and a user-friendly dashboard."
"Avolution ABACUS allows for flexible enterprise architecture analysis."
"It's more than just an enterprise architecture tool as it has a lot of nice features, e.g. messaging, simulation, etc."
"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."
"It is a very stable solution...The initial setup of Avolution ABACUS is very easy."
"The tool's implementation is straightforward as everything is readily available. For instance, setting up a portal is seamless, allowing easy publishing and access to data. However, integrating with other tools like BI, Power BI, or Grafana requires setting up pipelines between them."
"The most valuable feature is that it has a customizable meta-model, which is key."
"The user interface is good. It's both clear and comprehensible. It's easy to work with."
"We have seen ROI with this solution over the years that we have used it."
"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."
"The solution is pretty stable."
"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."
 

Cons

"Having more control over page size is lacking in this product. Print utilization also needs to be improved."
"The company needs to update the UML version they are using for the product as it is quite old."
"The reporting could be easier to configure."
"In the future, there could be improvements in integration and enhancements."
"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."
"It is vastly scalable but you can't run it on a Mac or Linux so it has limitations."
"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."
"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."
"The solution needs to better integrate with other products, like Microsoft."
"Some aspects of the user interface lack a common navigational or functional framework."
"This solution can be more user-friendly and easier to use, with better dashboards."
 

Pricing and Cost Advice

"The pricing is quite good compared to the competition and it is part of the reason we chose the product."
"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"
"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."
"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."
"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."
"There is a subscription for this solution. We are on an annual subscription because you sometimes receive special offers the longer you subscribe."
