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 portfolio management is really good, and the dashboard and the reports for the end-to-end impact analysis are really good."
"This product is very strong in terms of the meta-model because you can customize a lot according to the business plan."
"There are a lot of different features, but the business/decision-maker feature, visibility, and dashboards are most valuable."
"ABACUS is a really forward thinking product with a lot of nice features in it; it's not just all talk, it actually works."
"It's more than just an enterprise architecture tool as it has a lot of nice features, e.g. messaging, simulation, etc."
"If you want a data model of flexibility and catalog scalability I would recommend it from that perspective."
"You can design using a diagram tool installed on your desktop, a key difference from other vendors."
"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."
"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 user interface is good. It's both clear and comprehensible. It's easy to work with."
"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 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."
"The solution is pretty stable."
 

Cons

"The usability of the tool is an area with shortcomings that need improvement."
"The most valuable features are the catalog and the diagram."
"The tool doesn't have any intelligence built in. We have to design the dashboards ourselves, which is a challenge because we have to depend on the vendor for customizations."
"It doesn't have the simulation capability, which would be helpful in doing some business process analysis and improvements."
"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."
"While Avolution ABACUS is flexible, it can be complex to work with as it requires knowledge of specific configurations to customize the product."
"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."
"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."
"Some aspects of the user interface lack a common navigational or functional framework."
"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."
"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."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
"This solution can be more user-friendly and easier to use, with better dashboards."
"We are not happy with this product and are not planning to continue with it."
 

Pricing and Cost Advice

"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."
"The cost of Avolution ABACUS is reasonable, given the features they offer in comparison to other tools."
"There is a subscription for this solution. We are on an annual subscription because you sometimes receive special offers the longer you subscribe."
"It is expensive."
"The solution's pricing is not an issue."
"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."
