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.

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

"The ERwin tool helped to reduce the rate of design and deployment errors and increased the ease of validation."
"Its flexibility and scalability to support all stakeholders in making informed decisions are powerful capabilities."
"Evolve's reverse engineering ability is quite useful."
"Evolve is like a tank; you can do whatever you want with the solution, but you need to customize it."
"It is a customizable tool that allows you to do a lot of architectural modeling for customers, and you can use different kinds of diagrams to represent the architecture setting."
"Without this tool, we couldn't have made and defined all the new processes."
"Support for a broad range of data sources from relational to big data to the Cloud."
"Enterprise Architecture improved our organization by giving clarity over the data that is available."
"It has good end-to-end metamodel interrelationships."
"It is useful for creating build-outs and architecture views and for publishing reports and stuff like that for different programs."
 

Cons

"The solution needs to focus on allowing for more integrations."
"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."
"If it had fewer features to model all kinds of architecture, it would be less complicated."
"For what it says it can do, it does a good job, but using it is too difficult."
"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."
"Few clients looking are going with Evolve these days because I don't think they even appear on Gartner's Magic Quadrant."
"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."
"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."
"UNICOM System Architect is quite a dated tool. The usability needs to be improved."
"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

"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."
"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."
"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."
"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."
"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."
