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 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 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."
"The solution is pretty stable."
"The main advantage of the solution and its most valuable aspect is the customization of the meta-model."
"Integrating the Microsoft documents to the product and visualization matrix where we can see the end-to-end relationship of the network is of great importance to our company."
"I have to think less with this solution. It's simple."
"The solution has wide use within Microsoft products. The integration with Microsoft products, and, in particular, Microsoft Office, is great."
"From September 2014 through January 2015, I received help from the tech support staff of iServer, who were very prompt and almost instantaneously responded, and if it was something difficult, they brought three to four people to talk with me and then solved the problem within minutes."
"iServer is a solution that helps catalog enterprise architect solutions and catalog information."
"Tech support is very responsive. They solved issues within a prompt response time."
"This flexibility is the most helpful part in the standard version."
"This is a flexible tool compared to some other solutions."
 

Cons

"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."
"Some aspects of the user interface lack a common navigational or functional framework."
"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."
"We are not happy with this product and are not planning to continue with it."
"The performance is slow, which is something that should be improved."
"The one issue is that if you want to import predefined work, you need to put the licensing model in. So if you wanted to import work that was done before, you then need to buy a separate product for that."
"iServer should invest in enhancing the capabilities of the embedded drawing tool, draw.io."
"It's a very simple tool, which makes me concerned with the performance."
"iServer is a solid tool. Occasionally, we needed to contact the vendor to clarify details such as porting issues, missing components, and model specifics."
"Cannot see which activities are control activities."
"I do not find it friendly to use."
"The modelling needs improvement, specifically forecasting capabilities and scenarios."
 

Pricing and Cost Advice

Information not available
"The solution is cheaper than its competitors."
"The product has a moderate pricing."
"The price of iServer is reasonable compared to other solutions."
"It's about 13K to set up and 9K for the license for three months. I think it's about 20K a year, but we haven't firmed up on pricing yet because the price depends on how long we commit to the solution."
"Aim for the exact number of people who shall define/review approve and view the processes, as it will impact the cost."
"They offer annual subscriptions for developing countries, which are not affordable for small or medium businesses."
