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

"We can efficiently deploy business models into the databases and generate SQL scripts."
"I can send images in the PDF form, along with the relationships and the associations that are a very important part of what we do. It can show what is affected and what is impacted by a certain change in one area of the system architecture or enterprise architecture. I can very quickly draw those issues and topics to the fore."
"The initial setup was really straightforward and the deployment was done within one day."
"This product is a cross platform database designer, data inventory control and metadata library, and supports soft link integration."
"Customer Service: Outstanding Technical Support: Outstanding"
"By placing the data and the metadata into a model, which is what the tool does, you gain the abilities for linkages between different objects in the model, linkages that you cannot get on paper or with Visio or PowerPoint. That is a huge discriminator."
"Forward and reverse engineering were valuable features."
"I have not seen capabilities for web-sharing and interaction with the architecture from any other supplier. It's a great capability..."
"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 user interface is good. It's both clear and comprehensible. It's easy to work with."
"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 solution is pretty stable."
"We have seen ROI with this solution over the years that we have used it."
 

Cons

"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 way that we are using it for application management, we have several KPIs. We want to follow and monitor them regarding a number of solutions. We cannot calculate this today. We would like real-time calculations along with the KPIs in order to improve the user experience. We would like the tool to be able to display this, not only as signals, but as charts."
"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 feel that the UML drawing capability needs to be improved."
"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."
"The solution needs to focus on allowing for more integrations."
"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."
"Evolve is primarily focused on the entity's licenses diagrams, but it would be nice if erwin could integrate case development, so that it shows the ER diagram plus certain inputs on the use cases and how the data is used. That deviates somewhat from the overall scope, so maybe they could call it a different product."
"The solution needs to better integrate with other products, like Microsoft."
"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."
"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."
 

Pricing and Cost Advice

"On a yearly basis, our licensing costs are 50,000 euro. There are no additional costs because we are on a SaaS model."
"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."
"Yearly, our cost is €100,000."
"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."
"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."
