Featured Reviews

GM
IT/Business Architect at a financial services firm with 51-200 employees
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.

Senior Enterprise Architect at Deepview S.r.o.
Efficient documentation generation through organized model structure with a good price-performance ratio
Whenever I begin a new project with Sparx, I have to spend time training people on how to use it since it is not straightforward. Although it's a powerful product with plenty of features, it's not easy for even experienced users to find their way without guidance. This is not the most user-friendly solution.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"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."
"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 solution is pretty stable."
"In terms of product features, I'm very happy with the support for UML 2 diagrams, Archimate, TOGAF and the collaboration capability using a RDBMS back-end."
"The nature of this product did not justify an ROI but given a typical fully burdened rate for employee time, the sub-$1000 price tag is quickly recovered."
"The most valuable feature of Sparx Systems Enterprise Architect is the value streams."
"It's like a repository. So far, we use it only for Information Modelling."
"I am sure that the process of the developing of our product is faster and more secure through using Sparx."
"The solution is easy to use, supports SysML and UML, and is able to connect to MATLAB. This is very important for us."
"The best thing about the tool is that its database is open."
"The initial setup is easy."
 

Cons

"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."
"There needs to be more information at the outset about how to use the solution and how to deploy it."
"We are not happy with this product and are not planning to continue with it."
"Some aspects of the user interface lack a common navigational or functional framework."
"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 elements of the modeling sets can have better customization and visual representation. It would be great to have a mobile version."
"Personally, I had a hard time learning how business modeling works, and simultaneously learning a new tool."
"Running large and complex models (ours contained thousands of objects) does require a powerful machine with 8+GB of RAM."
"There were scalability issues. The HTML generation with very large models, over 4000 diagrams, can be problematic."
"The Portfolio Management features can be added in the next release. As it helps you to manage more portfolio of projects and architectures of cost projects on a portfolio level. This would be an important feature in the next release."
"Installation will be challenge for quick and one time use, some time the code not sync due to some issues."
"The integration could be improved."
"The database management area was not usable."
 

Pricing and Cost Advice

Information not available
"They have the price on their site for the enterprise version, and we do receive a small discount."
"This product has a paid license, with a yearly subscription option."
"Enterprise licensing is competitive. What would be helpful if they load the pricing for consultants, you know, people who are consultants for clients. So the license is fine for end-user organizations. Still, they should consider lowering the license to support this adoption, particularly for people who are consultants like myself."
"It is cheaper than other solutions. Its cost is around $686 per year. There are no costs in addition to the standard licensing fees."
"The Corporate Edition, or one of the bundles, is the way to go."
"The pricing for ultimate version is steeply high."
"In terms of cost, Sparx EA is probably one of the cheapest tools I have ever used."
"I rate the solution's pricing a five out of ten."
