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 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."
"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 user interface is good. It's both clear and comprehensible. It's easy to work with."
"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 solution is pretty stable."
"Its overall ease-of-use plays a big role in adoption."
"My advice to others looking into implementing LeanIX is that it's a pretty good tool if they're looking to reduce costs, but still want better IT."
"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 ability to import data and generate reports from it. That's where its power lies."
"I like the tool’s integration and maps."
"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 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."
"LeanIX has a great application information architecture."
 

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."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
"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."
"This solution can be more user-friendly and easier to use, with better dashboards."
"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."
"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."
"Some aspects of the user interface lack a common navigational or functional framework."
"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 pricing is a bit painful in the sense that it depends on the number of elements you fit in the system."
"LeanIX should improve its support services."
"The initial setup has room for improvement."
"The solution’s API integration needs to improve. I would like to see a digital screen watch feature also in the solution."
"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."
"What would make LeanIX better is more variety in terms of reporting, and more flexibility with its data importing feature."
"It's hard to predict the pricing of the system."
 

Pricing and Cost Advice

Information not available
"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 pricing is very good. We definitely get good value for the money."
"As the tool is cloud-based, its cost is more affordable."
"The solution's pricing is based on a licensing model that is competitive and in line with other products."
"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."
"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."
