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."
"There is a model behind it. It's really nice that the Evolve front-end, as it builds a website, keeps those relationships in mind. You can even go to a procedure and see all the applications that are related to it. Then you can go into that application and see all the standard operating procedures that that application is a part of. It's just very connected."
"One of the most valuable features is the website that sits on top of the database. There's a database of objects and how they are related, and you can make views and diagrams and visual elements out of that information on the website. The website is the part that is called Evolve and we use the Evolve Designer and publish the website out to our employees. They can click around and navigate and search, etc."
"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 ability to share and collaborate on the solution is its most valuable feature."
"The ERwin tool helped to reduce the rate of design and deployment errors and increased the ease of validation."
"We can efficiently deploy business models into the databases and generate SQL scripts."
"This is the first time that we have a central repository in our company where we can see and look at all the legacy applications which are used to serve the world."
"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."
"We have seen ROI with this solution over the years that we have used it."
"The solution is pretty stable."
"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."
 

Cons

"The solution needs to focus on allowing for more integrations."
"I would like it to be easier to make changes and then deploy them into production, especially when you have multiple web servers or front-ends. It would be nice to make a change and then have it propagate to the production servers in a more automated fashion."
"With the Excel importing, the "up to date" part is the challenge."
"They need to develop Evolve's user experience. For example, MEGA has a useful client view that helps with impact analysis. MEGA provides information about the processes, services, infrastructure, and portfolio of applications in one central view. It lets you see the periphery and relationships among components. This view is impressive, and Evolve doesn't have it."
"The solution's integration capabilities with other tools in our system has not been all that well done. We have people who use ARIS, who use System Architect and, of course, Visio. erwin has very limited ways to import and export from those kinds of tools. It's not a very easy thing to do."
"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."
"On upgrade– if the older models in the Workgroup Repository need to be upgraded, allow for a cascade update to newest version through the libraries."
"The solution's integration capabilities with other tools in our system has not been all that well done."
"The solution needs to better integrate with other products, like Microsoft."
"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."
"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."
"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."
 

Pricing and Cost Advice

"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."
"Yearly, our cost is €100,000."
"On a yearly basis, our licensing costs are 50,000 euro. There are no additional costs because we are on a SaaS model."
"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."
"I think erwin is quite expensive. I have difficulty selling the portal, in fact."
"Unless you are a one person shop – always go with the Workgroup edition and Concurrent licensing."
"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."
