IT/Business Architect at a financial services firm with 51-200 employees
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."
"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."
"The main advantage of the solution and its most valuable aspect is the customization of the meta-model."
"The user interface is good. It's both clear and comprehensible. It's easy to work with."
"The solution is pretty stable."
"The solution has wide use within Microsoft products. The integration with Microsoft products, and, in particular, Microsoft Office, is great."
"The most valuable features of iServer are the integration with Microsoft Office and the interface is similar to Microsoft applications making them easy to use."
"It has helped having data lineage in the business cluster, which is used as control artifacts."
"The most valuable feature is its reporting capability. It offers various packages for different types of reports, such as business and project management reporting packs."
"I love how there are no milestone swimlanes."
"The initial setup is easy."
"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."
"We like the governance."
 

Cons

"This solution can be more user-friendly and easier to use, with better dashboards."
"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."
"We are not happy with this product and are not planning to continue with it."
"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."
"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."
"It definitely needs help to improve the visual aspect of the solution."
"There could be features for process mining, process simulation, and analytics."
"I do not find it friendly to use."
"More visualization techniques and ways to report the data might be helpful."
"There are other solutions out there that have a better user interface."
"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."
"The migration tool needs to be included in the main package, and not as a separate license."
 

Pricing and Cost Advice

Information not available
"The price of iServer is reasonable compared to other solutions."
"Aim for the exact number of people who shall define/review approve and view the processes, as it will impact the cost."
"The solution is cheaper than its competitors."
"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."
"The product has a moderate pricing."
"They offer annual subscriptions for developing countries, which are not affordable for small or medium businesses."
