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.
Milan Sterba - PeerSpot reviewer
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

"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 solution is pretty stable."
"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."
"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."
"For the most part, we find that it is remarkable how inexpensive it is."
"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."
"It's like a repository. So far, we use it only for Information Modelling."
"We have found the stability to be very reliable."
"I tend to come back to Sparx because it is the best value for the money."
"The features I find most valuable is the ability to create a document and then put it into a OneCare artifact, which allows me to share the visual I bring about with other communities that are not system analysts because not everyone can afford to have a copy of Enterprise Architect, and additionally the solution operates well as a whole and has very comprehensive capabilities."
"I like that there is support for software patterns."
"Sparx Systems Enterprise Architect is very flexible and it is simple to define the metamodel, and additionally, it is lightweight on resources."
 

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."
"We are not happy with this product and are not planning to continue with it."
"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."
"The solution needs to better integrate with other products, like Microsoft."
"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."
"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."
"In a future release, they should improve portfolio planning."
"The stability and performance of Sparx Systems Enterprise Architect could still be improved. Setup for it is also slightly complicated and could be improved."
"Look and feel."
"The user interface is not so good. It's not easy for someone to use it at first. The product takes some getting used to."
"From a practical point of view, we need speed and reliability for creating a model and doing some really meaningful tasks such as application landscape, refactoring, etc. These are two primary criteria. Sometimes, when you import something, it creates the object duplicates, or it allows you to do something that you're not supposed to do. For example, validation is missing. This could be frustrating because when you work at a high speed, you need to come back and start fixing things that the tool allowed you to go with, which is not quite good. So, there should probably be some internal mechanisms to advise you about what you're doing and what is probably not the best idea."
"I think the UI could be improved and made a little bit more presentable."
"It took me a while to figure out how to use the report generation features effectively. So, it would be really nice if they had a way to make that a little bit more interactive and a little bit more straightforward."
 

Pricing and Cost Advice

Information not available
"We had a yearly license."
"I rate the solution's pricing a five out of ten."
"It’s the best deal in town, by far."
"Sparx Systems Enterprise Architect is priced well. The price we pay is approximately $20 per month. Other solutions I have found to be much more expensive."
"The licence has a costly upfront fee which gets you access. You have to pay an annual maintenance fee, which is less."
"The license I use is on-premise. We haven't gone to the cloud where we have to pay monthly or something like that. Sparx is cheaper than most similar tools."
"The pricing for ultimate version is steeply high."
"It's affordable. The only additional cost that we haven't yet figured out is the floating license. If you buy a floating license, you have to have a license management server, which comes at an additional cost that's not discussed. So, we haven't yet used the floating license. That’s because I haven't had a chance to figure that out."
