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

"Workgroup Repository collection of data models allows research across models without worry about platform incompatibilities and provides easy KPIs about corporate data assets."
"The ability to share and collaborate on the solution is its most valuable feature."
"I have not seen capabilities for web-sharing and interaction with the architecture from any other supplier. It's a great capability..."
"Forward and reverse engineering were valuable features."
"I really liked that it mapped out processes and was able to attach the data model to the appropriate process. You could map out the process, then when you got down to a specific couple of data elements, you could attach the table in the database that supported that process. You could connect it with erwin Data Modeler for that."
"You can use different kinds of diagrams to represent the architecture setting."
"The initial setup was really straightforward and the deployment was done within one day."
"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."
"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 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."
"The solution is pretty stable."
"The user interface is good. It's both clear and comprehensible. It's easy to work with."
"We have seen ROI with this solution over the years that we have used it."
 

Cons

"If it had fewer features to model all kinds of architecture, it would be less complicated."
"Business process modelling could be improved."
"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."
"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."
"It could have had a more streamlined navigation. It seemed that when you went to the explorer panel, there were just so many different ways of doing the work that I could not remember, "How did I do this? How did I get to that point in that model to get back to it?" If I wanted to build a new one, where do I start? It just seemed like there was such a smorgasbord of ways of doing it that it was just overwhelming."
"They have improved the search engine a little bit but it can always be improved more. The more data you put inside it, the more you want to use it."
"The solution needs to focus on allowing for more integrations."
"I feel that the UML drawing capability needs to be improved."
"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 can be more user-friendly and easier to use, with better dashboards."
"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."
"Some aspects of the user interface lack a common navigational or functional framework."
 

Pricing and Cost Advice

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