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."
"The solution is pretty stable."
"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 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 main advantage of the solution and its most valuable aspect is the customization of the meta-model."
"I like the tool’s integration and maps."
"LeanIX has good usability and stability. This SaaS is intuitive, easy to use, and comes with a nice reporting feature."
"The flexibility in the reporting has been extremely valuable, as we've been able to develop some nice looking reports and the dashboard's capability to map is very easy compared to Enterprise Architect."
"The ability to import data and generate reports from it. That's where its power lies."
"One of the product's most valuable features is its ability to configure hardware devices."
"I like LeanIX's ease of use in general."
"The usability is very high. It almost looks like a Facebook for Enterprise architecture, it's pretty nice. It's HTML5 based. The repository is very easy. It has 10 different ways of sorting the objects you have in your architecture repository. Maintaining new data or to add data to your repository is very easy."
"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."
 

Cons

"We are not happy with this product and are not planning to continue with it."
"Integration with all other software, like Microsoft, to facilitate an exchange, is not great."
"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."
"This solution can be more user-friendly and easier to use, with better dashboards."
"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."
"Some aspects of the user interface lack a common navigational or functional framework."
"The solution needs to better integrate with other products, like Microsoft."
"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."
"It would be beneficial to have additional features and capabilities to enhance mapping between applications, especially across domains where the relationships may not be direct."
"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."
"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."
"LeanIX experiences a lot of server timeouts. Nearly every transaction needs to be done twice due to these issues."
"Improvements in user interface simplicity could be made, particularly with the reporting and filtering capabilities."
"They could include a combination of LeanIX and some modeling extensions."
"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
"I would rate the pricing a one out of ten, where one is cheap, and ten is expensive."
"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."
"The pricing is very good. We definitely get good value for the money."
"LeanIX uses application-based account licensing, where the cost is multiplied by the number of applications in the software implementation."
"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."
"As the tool is cloud-based, its cost is more affordable."
