Director IT Architecture at QAD
Enables us to present data and objects visually, in diagrams, and to make them available via the web. Also enables web-based editing of data.
We tried their collaborative web modeling and we used it with a few people but we tend to not use that piece. We tend to collaborate with the people and then my team of architects draws up the diagram using the modeling tool. We then iterate through those. I would like to use it, but it was a little clunky when they first rolled it out. Overall, it's more about the company having room for improvement. What they need to do is to consolidate more of their products. For example, I was just looking and I couldn't figure out what erwin DT is. It's on the website but it would help if they could put information together and make it more clear as to what products they have and how they work with other things. I hear them talking in the support forums and, when I talk to the representative, they say they're going to do a bunch of stuff but it seems the progress is slow. The changes they need to make are to take their old, legacy product, which we use, and focus a lot on it so they can transform it into a modern cloud tool so that we have fewer little pieces to deal with. They could also fix their security model. It's very confusing to get new people onto the tool and to make sure that your content isn't being exposed to the wrong people.

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.

Quotes from Members

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

Pros

"Without this tool, we couldn't have made and defined all the new processes."
"Evolve is like a tank. You can do whatever you want with the solution, but you need to customize it. I think that it's not very aligned with the framework for enterprise architecture. MEGA is focused on these enterprise architectures, but it's only for that. With Evolve, you can do everything you want with professional services."
"The feature that stands out for me is the ease of configuring objects and the screens to show them. It's really easy to add a new type of object in this reference. Creating a new type of object, using it, and evolving it a little bit in terms of what we can document about it are the main features that made us decide to use this provider."
"The ability to share and collaborate on the solution is its most valuable feature."
"I really liked that it mapped out processes and was able to attach the data model to the appropriate process."
"Support for a broad range of data sources from relational to big data to the Cloud."
"The most valuable features for us are impact analysis, where I can easily visualize the impact of change."
"Forward and reverse engineering were valuable features."
"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 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."
"We have seen ROI with this solution over the years that we have used it."
"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. It's easy to work with."
"The user interface is good. It's both clear and comprehensible."
"The solution is pretty stable."
 

Cons

"What they need to do is to consolidate more of their products. For example, I was just looking and I couldn't figure out what erwin DT is. It's on the website but it would help if they could put information together and make it more clear as to what products they have and how they work with other things."
"With the Excel importing, the "up to date" part is the challenge. If we had a real-time integration, we could keep things up to date for whatever kinds of change points we had. With Excel, it is more that you have to export from one system then import it to another, so it's better for data that doesn't change that often."
"I would like it to be easier to make changes in development/testing and then deploy them into production more easily; especially when you have multiple web servers."
"The solution needs to focus on allowing for more integrations."
"erwin Evolve by Quest could have additional features to manage the architecture of enterprises and businesses."
"I feel that the UML drawing capability needs to be improved."
"There might be improvement required to better support some of the MPP databases for non-relational data structures and NoSQL databases."
"Business process modelling could be improved."
"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."
"There needs to be more information at the outset about how to use the solution and how to deploy it."
"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."
"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."
"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."
 

Pricing and Cost Advice

"Yearly, our cost is €100,000."
"The cost is something like $15,000, per license. But I haven't looked at those numbers in three years. It was over $100,000 to initially set everything up and get it all configured."
"Unless you are a one person shop – always go with the Workgroup edition and Concurrent licensing."
"I estimate that we pay between $40,000 and $50,000 a year for the solution, not including the upfront costs to buy things the first time."
"The licensing enables you to differentiate between people who edit the content and the people who consume it. We are able to keep the licensing costs down by keeping the "contributor" licenses to a minimum, and we then just roll out the content in a read-only version for the rest of our users."
"On a yearly basis, our licensing costs are 50,000 euro. There are no additional costs because we are on a SaaS model."
"I think erwin is quite expensive. I have difficulty selling the portal, in fact."
