Executive SummaryUpdated on Nov 3, 2024

IBM Rational System Architect and iServer compete in the enterprise architecture tools category, each providing distinct advantages. IBM Rational System Architect has the upper hand in pricing and support, while iServer’s extensive features deliver significant value.

Features: IBM Rational System Architect offers comprehensive modeling with simulation, analysis, and reporting. Additionally, it supports meta-frameworks like Zachman and TOGAF 9, versatile plugin and data importation features, and effective application portfolio scoring models. iServer is strong in collaboration and integration, excelling in seamless interaction with Microsoft Office, adaptive model design, and intuitive interface similar to other Microsoft applications.

Room for Improvement: IBM Rational System Architect could improve by enhancing cloud deployment options, making the interface more intuitive for new users, and reducing the complexity of its metamodel customization. iServer could benefit from improving its on-premise deployment capabilities, expanding modeling features beyond current integration options, and enhancing reporting customization to support more diverse frameworks beyond Microsoft environments.

Ease of Deployment and Customer Service: IBM Rational System Architect provides a traditional on-premise deployment that effectively integrates into existing IT frameworks, supported by reliable customer service. iServer, with its flexible cloud deployment model, allows for quicker setup and easy scaling, providing a versatile user experience. Both providers offer strong customer support, but iServer’s flexibility can improve the overall user experience during the deployment process.

Pricing and ROI: IBM Rational System Architect presents higher initial costs due to its extensive features but ensures substantial ROI through in-depth architectural insights. iServer might demand higher setup expenses credited to its integrated approach, but it provides excellent ROI via time-saving features and efficiency improvements through enhanced collaboration and strategic alignment. The initial investment in iServer is often validated by its overall cost-effectiveness for various enterprises.

Modeling is useful, but many features need improvement and technical support is lacking

I find that almost every feature related to the models requires improvement. For example, I would like to see more trendy models, the look and feel of the models can be improved. This solution can be more user-friendly and easier to use, with better dashboards. The impact analysis feature is in need of heavy improvement. The is a standalone product that lacks integration with a business process automation engine. I would like to see the workflow improved, where it integrates seamlessly with the artifacts.

More iServer pros

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."

"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."

"This solution can be more user-friendly and easier to use, with better dashboards."

"I haven't used this solution long enough to know what areas could 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."

"It definitely needs help to improve the visual aspect of the solution."

"We could allocate permissions to use only specific components to the users rather than the entire instance."

"Enhancing integration options with ERP or ITSM-related solutions for triggering automated requests for process definitions, changes, and tracking them in the iServer."

"The migration tool needs to be included in the main package, and not as a separate license."

"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."

"Requirements management needs to be improved."
