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

"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."
"It is simple to build the first model for the solution."
"It's easy to search within the solution."
"Its ability to reference and link to components from any diagram."
"The profiles allow me to customize the tool to the corporate environment instead of the other way around saving huge amounts of time and energy on trying to turn dozens of individuals into TOGAF, ArchiMate or Zachman experts, or even Sparx EA experts."
"We use it to develop and maintain the Enterprise Conceptual Model, migrated from erwin a couple of years ago."
"The stability has been good and satisfactory. I would rate the stability a ten out of ten."
"For the most part, we find that it is remarkable how inexpensive it is."
"Sparx has got a range of modeling features, and I am comfortable with all its offering. I've used a lot of tools over the phone. I found EA Spark, probably the most feature rich product all in all compared to other products. The solution is very cost-effective and that is its best feature. It's a very good delivery architecture tool, which also has enterprise architecture capabilities, and it's got full life cycle processes and software development. So for me, it's a pretty comprehensive tool"
 

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."
"This solution can be more user-friendly and easier to use, with better dashboards."
"The solution needs to better integrate with other products, like Microsoft."
"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 is quite complex to use. It would be nice if the learning curve wasn't so steep."
"Their technical support is not good in India. I wrote to them because I had a question, but I never got an answer. So, I just left it behind."
"The stability and performance of Sparx Systems Enterprise Architect could still be improved. Setup for it is also slightly complicated and could be improved."
"The product could be improved in terms of its ease of use and documentation. While it offers a lot of functionality, it can be difficult to grasp how to utilize these features effectively."
"The areas of improvement should be focused on utility service such as producing better graphics, perhaps having a wider image library set and producing better models for working directly with customers."
"They should make the Save button easier to find. A simplified user interface for a lighter user would probably be useful. I am not sure if such an interface is already there."
"It would be great if we could decrease the use of different parts of the Toolbox."
"The Business Process Modeling or BPM feature can be improved to make it more interactive and user friendly because it is a tool for technical people. My current use is only for business process modeling notation and putting in the icons etc. You need to take them in as a class, which makes things very complex. Because of this complexity, it is not an easy-to-handle solution. Enterprise Architect is not very good for mockups. We cannot create user screens and other similar kinds of stuff, which is bad. For these things, we prefer to use Axure RP and other similar solutions. They should either remove this feature from this product or provide some kind of connectivity with Axure RP so that people can do better mockups of screens and import them. They need to augment and strengthen the BPM feature, which is the main feature. They need to put in some elements like artificial intelligence and augmented reality. They should look into such features because these things are coming up."
 

Pricing and Cost Advice

Information not available
"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."
"It is very economical and low cost. You have to pay for a one-time license, and it is active forever."
"It’s the best deal in town, by far."
"The pricing is reasonable."
"This product has a paid license, with a yearly subscription option."
"I rate the solution's pricing a five out of ten."
"They have the price on their site for the enterprise version, and we do receive a small discount."
