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

"Avolution ABACUS allows for flexible enterprise architecture analysis."
"The most valuable feature is that it has a customizable meta-model, which is key."
"I would recommend it very strongly."
"The portfolio management is really good, and the dashboard and the reports for the end-to-end impact analysis are really good."
"The technical support is very good. They are responsive and the answers they provide are detailed."
"For what it does it is very good and a reasonable price."
"It is a very powerful tool that does what an enterprise architect needs it to do and it supports the business in knowing more about the business so that they can do better."
"It's a good product with a complete set of templates, frameworks, and notations."
"The solution is pretty stable."
"The main advantage of the solution and its most valuable aspect is the customization of the meta-model."
"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 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."
"The user interface is good. It's both clear and comprehensible. It's easy to work with."
 

Cons

"There are probably some things that Avolution could add to the product to enhance it and keep up with what some other products are introducing."
"In the future, there could be improvements in integration and enhancements."
"It doesn't have the simulation capability, which would be helpful in doing some business process analysis and improvements."
"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."
"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."
"For some of the functionality, it might be a little complicated for people getting started."
"If they want to expand in the European market then they are going to have to improve their technical support."
"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."
"We are not happy with this product and are not planning to continue with it."
"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."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
"Some aspects of the user interface lack a common navigational or functional framework."
"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."
"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."
 

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."
"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"
"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."
"The solution's pricing is not an issue."
"It is expensive."
"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."
