Transparency and Strategy for Your IT Architecture – with SAP LeanIX

Anyone who wants to successfully implement digital transformation projects needs one thing first: a complete, honest view of their own IT landscape. Without clarity regarding existing applications, their dependencies, and actual usage, it is impossible to assess risks or manage investments effectively.

The first step is often sobering: many companies simply do not know how many applications they actually run. LeanIX provides this overview – and abat ensures that it becomes a solid foundation for your transformation. 

What is SAP LeanIX – and how does Enterprise Architecture Management work?

LeanIX, part of the SAP portfolio as “SAP LeanIX” since 2023, is the leading cloud-based platform for Enterprise Architecture Management (EAM). It offers IT architects and CIOs a centralized, always up-to-date overview of the entire application landscape: Which systems exist? What dependencies are in place? Which applications are future-proof – and which are dispensable?

To achieve this, LeanIX uses a structured metadata model – known as fact sheets – to map applications, interfaces, IT components, and business capabilities in a standardized way. This creates transparent relationships between business, IT, and projects. At the same time, LeanIX identifies technology risks early on, such as when components are nearing end-of-support or critical dependencies rely on outdated technologies.

Furthermore, LeanIX supports companies not only in understanding their IT landscape but also in planning their transformation – for example, through scenario analyses and transformation roadmaps. LeanIX is an integral part of the SAP Integrated Toolchain and complements SAP Signavio (process level) as well as SAP Cloud ALM (project management). For companies planning an S/4HANA migration, developing a cloud- s strategy, or seeking to systematically reduce IT costs, this transparency is not optional – it is a prerequisite for informed decisions. 

How does abat work with LeanIX? An overview of our services

Step 1: IT Inventory and Assessment
Together, we map all relevant applications, interfaces, and dependencies in your IT landscape. LeanIX can integrate a wealth of information directly from existing systems – such as CMDBs, SAP landscapes, or cloud platforms – ensuring the inventory remains automatically up-to-date. The result is a complete, current application inventory – the foundation for all further decisions. Historically evolved structures become visible, responsibilities are clarified, and shadow IT is identified.

Step 2: Maturity Assessment and Areas for Action
Using the LeanIX framework and Business Capability Mapping, we assess the maturity level of each application: Which systems are future-proof? Where are there redundancies that drive up costs? Which applications can be consolidated or decommissioned? All results are documented in a structured manner within LeanIX – including responsibilities and architectural decisions—thus forming the foundation for clear IT governance. In the end, you’ll know which systems you should keep, consolidate, or decommission – based on sound reasoning, not gut instinct. 

Step 3: IT Target State and Roadmap 
Based on the assessment, we develop a realistic target vision for your IT architecture with a clear roadmap: timeline, priorities, and measurable milestones. This provides planning certainty for your management and IT teams. 

Step 4: Integration with SAP Signavio 
LeanIX reaches its full potential when combined with SAP Signavio: While LeanIX maps the technical IT architecture, Signavio optimizes the business processes built on top of it. Only this integration gives you a holistic view – of systems and the processes that support them. 

What exactly do companies use LeanIX for?

Identify migration risks before the project begins 

Determine which applications can be moved to the cloud – and which cannot 

Reducing license costs through targeted system consolidation

Manage IT investments based on usage data rather than estimates 

Clarify responsibilities and document architectural decisions in a transparent manner 

Planning transformations – for example, through scenario analyses and transformation roadmaps.

FAQs: Frequently asked questions about SAP LeanIX

SAP LeanIX provides a constantly up-to-date overview of your IT application landscape. The platform aggregates information from various sources, structures it, and reveals connections between applications. This creates a reliable foundation for understanding which systems are truly needed and which should be phased out in the long term. This sounds simple, but for many companies, it’s a critical blind spot. This transparency is especially crucial before an S/4HANA migration or when developing a cloud strategy. 

LeanIX operates at the IT architecture level: It shows which applications you have, how they are connected, and which of them fit into your future strategy. SAP Signavio, on the other hand, operates at the business process level: It analyzes how your processes actually run and where inefficiencies or deviations lie. abat uses both tools together because only this combination provides a complete view of IT and business.

LeanIX provides the answers that are crucial before an S/4HANA migration: Which legacy systems are linked to which processes? Which interfaces need to be rebuilt or adapted? Which applications can be phased out during the migration? Without this transparency, migration risks often only become apparent in the middle of the project – with LeanIX, they are known from the very beginning. 

Yes, LeanIX is scalable and not limited to large enterprises. Mid-sized companies in particular, with established IT landscapes planning an S/4HANA migration or a cloud strategy, benefit from the transparency that LeanIX creates in a short time. abat supports companies of all sizes and tailors the scope of implementation to your specific starting point.

Initial concrete results – such as a complete overview of your application landscape and initial maturity assessments – can typically be achieved with abat in four to eight weeks. The time required depends on the quality of your existing IT documentation and the number of systems to be captured. abat structures this process so that you quickly have actionable results in hand. 

No, LeanIX is system-independent and can map the entire application landscape – SAP systems as well as non-SAP applications, cloud services, and legacy systems. LeanIX is particularly valuable for companies in the SAP ecosystem because it is natively integrated into the SAP Integrated Toolchain and works with SAP Signavio and SAP Cloud ALM.
