GM
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.

General manager of Enterprise Architecture at Metcash Trading
Has provided a structured way to align business capabilities with IT while showing potential for support improvements
What it does is it creates a register in the documentation of all your applications and technologies. When you align or map it to your business capabilities, this is how you identify duplication of technologies in your business and how you can potentially rationalize and standardize on them. In conjunction with my business policies, LeanIX is quite effective because using it as a tool to determine what is an endorsed technology can prevent other technologies from being used. I would call it effective in preventing technology sprawl in my environment if it is used alongside my business policies. It does assist in aligning IT with business goals.

Quotes from Members

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

Pros

"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."
"The main advantage of the solution and its most valuable aspect is the customization of the meta-model."
"The solution is pretty stable."
"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."
"LeanIX is one of the best solutions available and its strengths lie in its prescriptive nature, guiding businesses to identify gaps and manage IT resources effectively."
"The most valuable feature would be application portfolio management, which is where they came from, but over time, they have got artificial intelligence. They built up a very good repository. If I identify a system by name, from historical information, oftentimes, they can tell me that this is deployed with this number of CPUs and they can give me a really good profile of the application for me to put it into a change management database with very little effort."
"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."
"LeanIX has good usability and stability. This SaaS is intuitive, easy to use, and comes with a nice reporting feature."
"For the reporting capabilities, LeanIX provides dashboards for different levels, including CXO dashboards. There are plenty of dashboards for reporting."
"The solution has a very useful assessment tool that automatically populates from input data to produce a detailed analysis of customer's environments."
"I like the tool’s integration and maps."
"I do see some return on investment, some ROI, time saving, money saving; it's more than 30%, so ultimately, the work that I do in using LeanIX will pay for itself."
 

Cons

"Some aspects of the user interface lack a common navigational or functional framework."
"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 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."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
"We are not happy with this product and are not planning to continue with it."
"This solution can be more user-friendly and easier to use, with better dashboards."
"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."
"The challenge with support was probably the response time."
"What would make LeanIX better is more variety in terms of reporting, and more flexibility with its data importing feature."
"They could include a combination of LeanIX and some modeling extensions."
"The whole integration architecture view of interfaces/data exchange could be improved."
"LeanIX should improve its support services."
"LeanIX has limited in-build diagramming capabilities, requiring the purchase of another tool. That is the main drawback of LeanIX because they don't have a built-in add-on product for diagramming."
"They should improve the out of the box connectors that they provide. They should see if clients are really ready to adapt them."
"They're probably positioned pretty well. I hope that they would not focus that much on the business architecture, and they would focus more on the overall cloud strategy and how we can leverage multi-cloud and transition back and forth from other cloud providers. With a lot of current vendors, you get locked in with one cloud, and then you try to migrate to someone else, and it becomes very problematic. What they need to do is to look at the overall data strategy, and they probably need to amplify their data strategy, especially around multi-cloud."
 

Pricing and Cost Advice

Information not available
"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."
"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."
"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."
"I would rate the pricing a one out of ten, where one is cheap, and ten is expensive."
"LeanIX uses application-based account licensing, where the cost is multiplied by the number of applications in the software implementation."
"The pricing is very good. We definitely get good value for the money."
"The solution's pricing is based on a licensing model that is competitive and in line with other products."
