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

"I would recommend it very strongly."
"It is a very stable solution...The initial setup of Avolution ABACUS is very easy."
"The technical support is very good. They are responsive and the answers they provide are detailed."
"The most valuable feature is that it has a customizable meta-model, which is key."
"The most valuable feature is the traceability, you can trace any object to the other."
"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."
"The portfolio management is really good, and the dashboard and the reports for the end-to-end impact analysis are really good."
"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."
"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."
"The main advantage of the solution and its most valuable aspect is the customization of the meta-model."
 

Cons

"This solution needs to improve resource usage because it has a heavy browser. It is easy to use, but it takes time to load and to run other programs."
"Having more control over page size is lacking in this product. Print utilization also needs to be improved."
"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."
"While this is one of the most powerful tools on the market it does not integrate well with Microsoft Office or others."
"It is vastly scalable but you can't run it on a Mac or Linux so it has limitations."
"The usability of the tool is an area with shortcomings that need improvement."
"It doesn't have the simulation capability, which would be helpful in doing some business process analysis and improvements."
"It needs more flexible analysis parameters and more capability as a BPM tool and doing BPM simulation, compared with Bonita BPM or Bizagi."
"The solution needs to better integrate with other products, like Microsoft."
"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."
"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."
"Some aspects of the user interface lack a common navigational or functional framework."
"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."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
 

Pricing and Cost Advice

"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."
"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 solution's pricing is not an issue."
"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."
"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."
