LeanIX — Application Portfolio & EA

Enterprise architecture visibility — application health, tech debt, capability mapping, and SAP landscape rationalisation.

SAP LeanIX Integration: LeanIX connects directly to your SAP landscape via the LeanIX + SAP integration for S/4HANA, BTP, and RISE. Application data, interface maps, and technology obsolescence signals flow bidirectionally into the Sierra Digital advisory platform — ensuring the EA model reflects the live system landscape, not a point-in-time spreadsheet.

Methodology (S18)
How every number here is derived
Data sources: Application count derived from client.systems + 0.45 × client.interfaces (LeanIX benchmark: 2.2 interfaces/app). Tech debt score = max(28, 82 − avgCompliance). Rationalisation target = 22% of portfolio (Gartner APM benchmark). Capability coverage scores are Sierra Digital benchmark averages across 47 ECC landscapes — for live engagements, pulled from LeanIX Fact Sheet API. Full methodology →
