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

"The solution is pretty stable."
"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."
"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 main advantage of the solution and its most valuable aspect is the customization of the meta-model."
"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."
"Customizable and tailored to the environment. Several template frameworks are provided."
"SPARX EA is well suited for a client that does not have an Enterprise Architecture or Business Process and that needs to get started, so you can leverage the product right from scratch."
"Large variety of profiles and frameworks available out-of-the-box without the need for customization, and not locked into one way of doing architecture."
"It's like a repository; so far, we use it only for Information Modelling."
"Ability to use a single shared repository and defined languages, using both ArchiMate as the modelling language and the business language based on the repository contents."
"Using Sparx Enterprise Architect allowed my customer to detail and make the company's IT strategy visible and accessible to all."
"Its most valuable feature is the Zachman Framework."
"Large diagrams for hardware infrastructure, HA environments, Integrated Solution view, etc all help different teams to understand the scope of projects."
 

Cons

"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."
"We are not happy with this product and are not planning to continue with it."
"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."
"There needs to be more information at the outset about how to use the solution and how to deploy it."
"Some aspects of the user interface lack a common navigational or functional framework."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
"Its usability needs to be improved. For non-technical users, it is a little difficult to understand how Enterprise Architect works."
"This solution should have better ease of use for the uninitiated."
"If you just want to create some diagrams with shapes and arrows, then use Visio."
"The reporting needs improvement."
"The reporting needs improvement."
"The initial setup of the Sparx Systems Enterprise Architect is very complicated. It's very difficult to start with the right templates because there are many possibilities."
"I think the solution could be improved visually. It's not as visually appealing as other solutions."
"Because it's easy to create diagrams one needs to be vigilant on the housekeeping of orphaned fragments - I have written my own scripts to do this, maybe they are available now."
 

Pricing and Cost Advice

Information not available
"It is cheap."
"Pricing and licensing is very attractive, simple, and straightforward."
"It's reasonably priced for large organizations."
"I use my own license. So, I just bought the professional version, which costs $800 or something like that. In the company where I am working, we have floating licenses. They are probably more expensive. Its licensing is affordable, but we are talking about a large organization, and there could be modelers or viewers of the models. We don't know how much that would cost us."
"The pricing is reasonable."
"I rate the solution's pricing a five out of ten."
"The licence has a costly upfront fee which gets you access. You have to pay an annual maintenance fee, which is less."
"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."
