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."
"The portfolio management is really good, and the dashboard and the reports for the end-to-end impact analysis are really good."
"It is a very stable solution...The initial setup of Avolution ABACUS is very easy."
"If you want a data model of flexibility and catalog scalability I would recommend it from that perspective."
"For what it does it is very good and a reasonable price."
"ABACUS is a really forward thinking product with a lot of nice features in it; it's not just all talk, it actually works."
"There are a lot of different features, but the business/decision-maker feature, visibility, and dashboards are most valuable."
"I would recommend it very strongly."
"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."
"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 main advantage of the solution and its most valuable aspect is the customization of the meta-model."
"We have seen ROI with this solution over the years that we have used it."
 

Cons

"Based on my experience, this is not a product that I recommend at the moment."
"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 needs more flexible analysis parameters and more capability as a BPM tool and doing BPM simulation, compared with Bonita BPM or Bizagi."
"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."
"The reporting could be easier to configure."
"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."
"Some aspects of the user interface lack a common navigational or functional framework."
"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."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
"The solution needs to better integrate with other products, like Microsoft."
"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."
"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."
 

Pricing and Cost Advice

"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"
"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."
"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."
"My company makes annual payments toward the licensing costs of the solution. Considering the product's capabilities, its prices are very reasonable."
