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

"The main advantage of the solution and its most valuable aspect is the customization of the meta-model."
"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."
"The user interface is good. It's both clear and comprehensible. It's easy to work with."
"The solution is pretty stable."
"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."
"Good and effective reporting features, which help in decision making."
"Process modelling through object creation and management is beneficial as a very effective change management of processes at the object level, because if you need to modify a process and it will impact other processes as well, the object changed automatically changes in other processes as well."
"This is a flexible tool compared to some other solutions."
"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."
"iServer is a very flexible platform for defining your own enterprise architecture 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."
"There were lots of different requirements, and collaboration and review is one of the biggest things. There is also Office 360 integration, and there's flexibility to use it as a database as well."
"The solution is easily modified to suit your needs."
 

Cons

"We are not happy with this product and are not planning to continue with it."
"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."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
"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."
"Some aspects of the user interface lack a common navigational or functional framework."
"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."
"Setting up the Portal was very complex. We required a lot of support from the vendor."
"There can be some performance issues using the solution that should be improved. When you make modifications modify to files there are embedded data within that can take a while to process."
"It definitely needs help to improve the visual aspect of the solution."
"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."
"Cannot see which activities are control activities."
"iServer is a solid tool. Occasionally, we needed to contact the vendor to clarify details such as porting issues, missing components, and model specifics."
"I haven't used this solution long enough to know what areas could be improved."
 

Pricing and Cost Advice

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