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.

Useful for creating build-outs and architecture views, but requires a publisher add-on for some detailed reports
I don't use the tool or know a lot. It is going to have some shortcomings. When it comes down to publishing, we just found out this week that they actually have a publisher add-on. So, what we were trying to publish was not giving a detailed report about the architecture, views, etc. I just wish they had sent these to UNICOM and contacted them about add-on features for the publishing part of the tool.

Quotes from Members

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

Pros

"We use it to develop and maintain the Enterprise Conceptual Model, migrated from erwin a couple of years ago."
"The installation was very easy."
"The features I find most valuable is the ability to create a document and then put it into a OneCare artifact."
"Ability to model and create view under same roof."
"Provides a single repository for all architecture work."
"It has led some teams to do better code reviews - to be less focussed on coding conventions (syntax) and more focussed on the semantics because of the abstraction level clear design affords."
"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"
"We have found the stability to be very reliable."
"It is useful for creating build-outs and architecture views and for publishing reports and stuff like that for different programs."
"It has good end-to-end metamodel interrelationships."
 

Cons

"I think that collaboration can be better."
"For data modeling, it is not very mature when comparing with other data modeling tools."
"It can be improved in the area of shared documentation. The idea is that the architecture tool can call back to an enterprise asset, pull that information, and link that as a sub-artifact."
"It really did not work for logical modeling. The look is very old-fashioned. You can't make the diagrams easy on the eye, so we ended up drawing them again in Visio anyhow."
"The documentation needs a bit of improvement. What I find is that when I'm trying to do something specific for some part of a project, in terms of documentation, it's kind of hard to get at figuring out if you don't use it all the time."
"The window froze for five or ten seconds. You can click and click again and it takes a second to come up. It might have been specific to a version."
"Because its 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."
"Not visually appealing."
"They need to add reports that show the enterprise architecture perspectives, and the dashboards should be comfortable for the senior enterprise architects so that they can view the complete landscape."
"I don't use the tool or know a lot. It is going to have some shortcomings. When it comes down to publishing, we just found out this week that they actually have a publisher add-on. So, what we were trying to publish was not giving a detailed report about the architecture, views, etc. I just wish they had sent these to UNICOM and contacted them about add-on features for the publishing part of the tool."
 

Pricing and Cost Advice

"It is cheap."
"Pricing and licensing are suitable even for small companies."
"They have the price on their site for the enterprise version, and we do receive a small discount."
"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."
"The pricing is reasonable."
"It is very economical and low cost. You have to pay for a one-time license, and it is active forever."
"Its price is very good for the value that you get with it."
"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."
"I don't remember the price. It is a different cost for just buying it, and then you have a maintenance cost, which you need to renew every year."
