Executive SummaryUpdated on Nov 3, 2024

IBM Rational System Architect and LeanIX are competitors in the enterprise architecture domain. While LeanIX stands out for its comprehensive feature set, IBM Rational System Architect offers notable advantages in pricing and support, presenting a clearer value proposition in these areas.

Features: IBM Rational System Architect is praised for its robust modeling capabilities, comprehensive integration with IBM tools, and its value in detailed architecture planning. LeanIX provides user-friendly collaboration, quick adaptability, and advanced features like cloud-based accessibility and streamlined data integration, making it superior for modern enterprise needs.

Room for Improvement: IBM Rational System Architect could enhance its deployment agility and update its user interface for better usability. It's also crucial to improve integration options with non-IBM ecosystems. LeanIX could benefit from reducing its high initial investment cost, expanding customization options, and enhancing offline capabilities for environments with limited internet access.

Ease of Deployment and Customer Service: LeanIX's cloud-native deployment offers quick setup and flexibility, with a strong focus on customer-centric support. In contrast, IBM Rational System Architect may involve a more complex deployment process, yet it benefits organizations with existing IBM ecosystems through its wide range of integration options and established support protocols.

Pricing and ROI: IBM Rational System Architect provides a cost-effective setup with favorable long-term ROI when used within IBM infrastructures, making it attractive for budget-conscious clients. LeanIX, while requiring a higher initial investment, justifies this with its scalability and advanced features, promising potentially higher ROI for dynamic organizations prioritizing operational agility.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"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 solution is pretty stable."

"The user interface is good. It's both clear and comprehensible. It's easy to work with."

"We have seen ROI with this solution over the years that we have used it."

"For the reporting capabilities, LeanIX provides dashboards for different levels, including CXO dashboards. There are plenty of dashboards for reporting."

"The most valuable features are the clean user interface and the fact sheet feature in Application Portfolio Management. The tool integrates well with ServiceNow, which is the usual CMDB platform."

"Interfaces well with downstream systems of data."

"Among the most valuable features are the easy-to-use interface and the ability to get quick results... Many tools that I have seen are great for technical people and for giving technical and business information as well, but they're not as friendly and easy as LeanIX... It works well for both technical and business users. It provides a good combination, enabling you to quickly put valuable information in for both technical and non-technical people and derive results."

"I like LeanIX's ease of use in general."

"LeanIX has a great application information architecture."

"Ease of use is the most valuable feature. From an enterprise architecture perspective, it's not too cumbersome with too many functionalities, yet it has a lot of attributes for the content it covers."

"The most valuable features include the reporting capabilities and the LeanIX Academy's educational resources."

More LeanIX pros

Cons

"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."

"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."

"Does a poor job of being able to allocate detailed costings to components within the network."

"Report generation could be more detailed. There are some shortcomings when creating reports. We can't create tag-based reports or go beyond basic technical reports."

"LeanIX should improve its support services."

"I think the tool's main issue might be direct integrations."

"Another area for improvement is that when you're starting to look into more advanced information, using the solution's APIs and its customizations, documentation for that specific aspect is not very good. There is not too much support built into the offering for that aspect, for a developer."

"The solution uses Gartner's time-based framework for application rationalization. One more thing that you can consider is having some add-on frameworks for the same, not just Gartner."

"I find LeanIX's pricing expensive for the functionality it offers. However, with the acquisition by SAP, the pricing might become more affordable due to scale and tiered application pricing. Currently, it offers different tiers for the first 400 applications: 400 to 600 and 600 to 1,000, making it expensive from a pricing standpoint."

"What would make LeanIX better is more variety in terms of reporting, and more flexibility with its data importing feature."

Pricing and Cost Advice

Information not available

"The solution's pricing is based on a licensing model that is competitive and in line with other products."

"It cost me $91,000 a year for 300 applications. For any enterprise, 300 applications are minimal, as many have well over 1,000 applications."

"I would rate the pricing a one out of ten, where one is cheap, and ten is expensive."

"As the tool is cloud-based, its cost is more affordable."

"The tool needs to include more flexible licensing options. We do not use the tool all the time. So pricing should be considered only when we use the tool."

"LeanIX uses application-based account licensing, where the cost is multiplied by the number of applications in the software implementation."

"There is a sweet spot of where they need to be on pricing right now. They could go up a little bit in pricing, but it has to do with the cost savings, and it has to do with the practitioners using it. I use it where I get cost savings and I can justify it, but they probably have the ability to flex a 10% up channel on their sales on that. So, they could increase their settle price, not their offering price, when they sell. They can probably hold that up a little bit higher than it is because there are cost savings that we can drive from it."

"The pricing is very good. We definitely get good value for the money."
