Why use LeanIX and S4SensAI together for SAP programmes?
LeanIX gives you real-time visibility into your SAP landscape, showing what systems you have, how they connect, and what's at risk.
S4SensAI is Resulting's agentic AI platform that provides the SAP-specific expertise to turn that visibility into action: custom code verdicts, integration architecture designs, and board-ready business cases.
Together, they solve the two biggest SAP S/4HANA planning challenges: not knowing enough about your current landscape to make confident decisions, and not having the SAP expertise to act on what you discover.
Key benefits of using both:
- LeanIX: Live, structured map of your entire SAP estate
- S4SensAI: SAP knowledge engine that tells you what to do with that map
- Combined: Faster decisions, evidence-based plans, and genuine capability building versus consultant dependency
Why LeanIX, and why now
Most SAP estates weren't designed in one go. They were built up over years, sometimes decades, through a mix of deliberate decisions and pragmatic compromises made under pressure.
ECC sits at the centre. Around it, a constellation of satellite systems: third-party integrations, custom Z transactions, bolt-on solutions, and cloud applications that were procured outside of IT governance because a business unit needed something and needed it quickly.
Three forces driving continuous IT transformation
At the same time, IT organizations are being pushed into continuous transformation. Three forces are driving this:
- Business transformation including large-scale ERP transformations that touch every part of the business
- The rise of digital platforms and the organizational change needed to compete in software-centric models
- Generative AI accelerating change and increasing the need to re-architect products, services, and the technology landscape
As these forces compound, the IT landscape becomes more complex, often in ways that are hard to see. Much like an iceberg, the most dangerous dependencies sit below the surface.
The problem this creates
When a major decision lands (a migration, a system retirement, a re-architecture), the questions that matter most take weeks to answer:
- Which systems are actually in scope for the SAP S/4HANA migration?
- Which integrations need to be rebuilt from scratch?
- What breaks if you decommission that system you've been meaning to retire for three years?
By the time you've tracked down the answers, chased the people who know, and reconciled three different versions of the truth, the picture has already moved on.
What does LeanIX solve for SAP landscapes?
LeanIX is an enterprise architecture management (EAM) platform that provides enterprise architects, CIOs, and business stakeholders with a single, living source of truth for the IT landscape and its business interdependencies.
What LeanIX provides
It gives a 360° view of the software landscape, including SaaS and self-built software, and shows how that landscape relates to the business and transformation initiatives.
In practice, LeanIX supports organizations to:
- Inventory, document, and understand the current IT landscape
- Plan and design a target architecture and a roadmap from as-is to target
- Oversee implementation of architectural change and transformation execution over time
What this means for SAP S/4HANA programmes
For SAP technology leaders preparing for SAP S/4HANA, this means you can see, with current data, not last quarter's spreadsheet, exactly where you stand:
- Which parts of your landscape are affected by the migration
- Which integrations are at risk and where dependencies exist
- Which applications are candidates for retirement
- Which capabilities are currently served by custom SAP code that SAP S/4HANA may already cover in standard
How LeanIX operationalizes continuous transformation
LeanIX helps operationalize continuous transformation through three principles:
- Standardization: Aligning on a shared model and language so teams spend less time debating data structures and more time improving portfolios
- Simplification: Managing complexity without adding more complexity; focusing on usability and letting integrations do the heavy lifting
- Collaboration: Enabling business and IT to work with a shared language, with extensibility through open APIs and partner ecosystems
LeanIX differentiators that matter in practice
LeanIX is designed to drive fast time-to-value and sustained adoption through:
- A predefined, fully configurable meta-model based on best practices
- Built-in reference catalogues that support automation of previously manual enterprise architecture work
- Automatic SaaS discovery to improve visibility of SaaS growth and decentralized procurement
Baseline benefits LeanIX creates
A single source of truth for the architecture landscape:
- Democratizes architectural transparency
- Supports data-driven decisions
- Enables collaboration across often siloed organizations
- Drives better business outcomes: higher agility, reduced risk, and lower cost
What is the honest gap LeanIX leaves for SAP-specific decisions?
This is the part that doesn't always make it into the sales conversation, so we'll say it plainly.
LeanIX gives you the map. It doesn't make SAP-specific decisions for you.
That isn't a criticism. LeanIX is an architecture management platform. It's exceptional at giving you visibility, structure, and governance. It wasn't designed to be an SAP knowledge engine, and it shouldn't have to be.
The SAP expertise gap in detail
Custom code decisions: Knowing you have 3,400 custom Z transactions is valuable. Understanding which are redundant in S/4HANA, which need re-engineering on BTP, and which represent genuine business requirements S/4HANA can't meet requires deep SAP expertise LeanIX doesn't carry.
Integration architecture decisions: Knowing you have 47 integrations touching SAP core is valuable, but understanding the architecture implications of each and which integration patterns fit your scenario requires SAP-specific knowledge.
An interface list doesn't tell you what to fix first or what "good" looks like. You need something that turns inventory into action: risk heatmap, target pattern recommendations (point-to-point to API/event via hub), and a phased roadmap with quick wins.
Portfolio rationalisation decisions: Survey data doesn't create a plan. You need to convert functional-fit and technical-fit signals into rationalization decisions (retain/tolerate/migrate/eliminate), then produce a wave-based decommission roadmap with expected savings and next validation steps.
Mission-critical end-of-life planning: End-of-life signals need to become a migration plan: rank applications by risk (lifecycle + fitness + SLA/hosting), translate risk into estimated outage exposure so leaders can prioritise with financial clarity, and produce a wave roadmap showing what must move now versus what can wait.
How does S4SensAI complement LeanIX for SAP programmes?
S4SensAI is Resulting's agentic AI platform built specifically for SAP. It deploys a team of specialist AI agents, each drawing on a curated SAP S/4HANA knowledge base built over nearly a decade of independent SAP consulting.
It doesn't replace LeanIX. It sits alongside it as the AI knowledge and delivery engine that turns architecture insight into action.
| What you need | LeanIX provides | S4SensAI adds |
|---|---|---|
| Landscape architecture decisions | Visual map of what's in your landscape | SAP-specific guidance on what to do with each component, credible answers in minutes instead of weeks |
| Custom code strategy | Volume and lifecycle status of custom development | ABAPBanZAI: Classifies every Z object, maps to business processes, reconstructs functional specs, produces object-by-object clean core verdict |
| Integration architecture | Interface inventory and dependencies | SAP architectural expertise to design what integrations should look like in S/4HANA clean core model, risk heatmap, target patterns, phased roadmap |
| Portfolio rationalization | Survey signals on functional and technical fit | Converts signals into decisions (retain/tolerate/migrate/eliminate), wave-based decommission roadmap with savings estimates |
| Business cases | Capability gap identification | Basho: Converts gaps into quantified, CFO-ready business cases translating SAP functionality into tangible value |
| Delivery acceleration | Architecture governance structure | Puma: Builds project plans, risk registers, programme artefacts in minutes. Dev Dogen: Writes technical specs and first-draft code for BTP extensions |
How the integration works in practice
Your architecture team can interrogate S4SensAI on the SAP implications of specific landscape decisions and get credible, detailed answers in minutes rather than weeks. That analysis feeds directly into the architecture picture LeanIX is managing, creating a continuous loop from visibility to expertise to action.
How do LeanIX and S4SensAI turn portfolio signals into funded plans?
LeanIX gives you the picture. S4SensAI tells you what to do with it.
When your landscape data shows a high share of applications in "Migrate" and "Eliminate" status, it's a clear signal of technical debt, misaligned spend, and transformation urgency. In most organizations, converting that signal into decisions takes months of workshops, spreadsheets, and senior consulting time.
S4SensAI compresses that work into days by pairing two capabilities: BenefitsBasho and PlanPuma.
What BenefitsBasho produces from the portfolio picture
Using the portfolio picture as input, BenefitsBasho:
- Identifies rationalization themes (for example, end-of-life applications and duplicated regional capabilities)
- Quantifies savings drivers (licence termination, hosting decommission, reduced support overhead, simplified integration maintenance)
- Packages a board-ready narrative
Example outcome from a TIME-based portfolio picture:
- Eliminate end-of-life / unfit applications: £1.2M to £1.5M estimated annual saving, 6 to 12 months
- Consolidate duplicates + migrate legacy ECC modules: £500K to £800K estimated annual saving, 12 to 24 months
- Total: £1.7M to £2.3M estimated annual saving across 47 applications, 6 to 24 months
(These figures are an example of what a portfolio triage can surface when the underlying data is available.)
What PlanPuma produces: from business case to executable plan
PlanPuma takes the prioritized opportunities and produces delivery artefacts that move the programme from "analysis" to execution:
- A sequenced plan (quick wins first, dependencies made explicit)
- A workstream structure aligned to an SAP S/4HANA migration programme
- A risk register and governance-ready tracking
- A clear next-steps checklist (data gaps to close, validations to run, decisions to take)
The result: The portfolio picture becomes an approved business case and an executable plan without waiting for a long consulting cycle.
Net effect: architects spend time deciding, not compiling, and you get an executable transformation plan instead of another workshop cycle.
What do organizations get from using both platforms?
Organizations that use LeanIX alongside S4SensAI get something neither tool delivers alone.
Better decisions
LeanIX gives you the architecture visibility and governance structure to manage a complex SAP landscape with confidence. S4SensAI gives you the SAP knowledge and delivery capability to act on what you see, faster, at greater depth, and at a fraction of the cost of traditional consulting.
Faster programmes
The analytical and generative work that traditionally consumes months of senior consulting time gets compressed to days. Your programme moves faster because the bottleneck shifts from "waiting for analysis" to "making decisions with evidence."
Genuine capability building
Your organization builds real capability rather than growing dependent on external expertise for every decision. That matters long after the migration is done. Your team comes out the other side knowing more than when they went in.
Who this supports
This combined approach benefits:
- Enterprise architects and CIOs: Understand future readiness, tech risk, and cost
- Solution architects: Get guidance and accelerate architecture decisions
- IT security: Manage and reduce landscape risk and exposure
- Transformation managers: Create transparency across programmes and projects
- Application and business owners: Stay on top of responsibilities and decision impacts
The two biggest SAP S/4HANA challenges solved
For SAP technology leaders preparing for SAP S/4HANA, this combination addresses the two challenges that stall most programmes in the planning phase:
- Not knowing enough about your current landscape to make confident decisions
- Not having access to the SAP expertise you need to act on what you discover
LeanIX solves the first. S4SensAI solves the second.
Where should you start?
If you're planning an SAP S/4HANA migration or managing ongoing SAP landscape transformation, the combination of LeanIX and S4SensAI closes the gap between knowing and doing.
What you get from using both:
- LeanIX: A live map of your entire SAP estate, always current, always structured
- S4SensAI: The SAP knowledge to read that map and act on it with confidence
- Combined: Faster decisions, sharper analysis, and real capability built inside your team rather than rented from a consultancy
Your SAP S/4HANA programme moves faster. Your dependency on traditional consulting costs drops, and your team builds genuine expertise rather than consultant dependency.
