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.

Building Strategic Enterprise Architecture Journeys with Comprehensive Process Mapping and Risk Management
They will continue to improve LeanIX. I'm actually supposed to be at the SAP Sapphire this year. There are a couple of recommendations I know some of my colleagues have made. For me, I have not looked into additional recommendations for LeanIX because I've been held in really just utilizing it for the purposes it has. One of the things that I know I've had is being able to build it into decent process flows for changes. While LeanIX does have the capability, one of the challenges that I've found, even with working with Subway, was that being able to build that out into a detailed solution for a developer or for new process design was one of the challenges, just making that leap. But there's enough information that comes out of LeanIX to be utilized, and that would be one of the areas I would suggest.

Quotes from Members

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

Pros

"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."
"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 most valuable features include the reporting capabilities and the LeanIX Academy's educational resources."
"It offers neat visualization and referencing functionality while enabling the creation of landscape maps and showing the relationship between different applications."
"Interfaces well with downstream systems of data."
"I would rate LeanIX at an 8.5, trending towards nine."
"I like LeanIX's ease of use in general."
"One of the most valuable features of LeanIX is the Enterprise Architecture Management tool."
"We've been able to develop some nice looking reports, and the dashboard's capability to map is very easy compared to Enterprise Architect."
"My favorite feature of LeanIX is its ability to induct attribute-driven surveys."
 

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 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."
"The solution’s API integration needs to improve. I would like to see a digital screen watch feature also in the solution."
"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 think the tool's main issue might be direct integrations."
"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."
"The modeling could be improved."
"Does a poor job of being able to allocate detailed costings to components within the network."
"The whole integration architecture view of interfaces/data exchange could be improved."
 

Pricing and Cost Advice

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

What is your experience regarding pricing and costs for LeanIX?
My experience with pricing is not directly known, as it was handled by others, but it is subscription-based. The tool was part of the RISE license in a previous project.
What needs improvement with LeanIX?
From a pricing perspective, it is not a cheap tool. It is relatively expensive compared to some of its competitors. I can't really think off the top of my head at the moment about any features that...
