Future-ready your application landscape with SAP LeanIX

Define your modernization strategy

  • Start with clarity, not complexity. Align on what "modern" means for your organization, whether that's cloud-first, API- enabled, or infrastructure renewal, so every modernization decision ties back to business outcomes.
  • Bring IT, business, finance, and compliance stakeholders together around shared objectives. Capture KPIs and OKRs in the Objective Fact Sheet and link them directly to transformation initiatives.
  • Set realistic timelines with built- in milestone planning, so leadership has a clear view of what's coming and when, from pilot rollouts to full-scale migration.
Define your modernization strategy
Assess your application portfolio

Scope and assess your application portfolio

  • Get a clear picture of which applications are candidates for modernization. Filter by lifecycle, hosting type, and TIME classification (Tolerate, Invest, Migrate, Eliminate) to quickly narrow scope and focus resources where they matter most.
  • Eliminate months of manual data gathering. Automated surveys, built-in to-dos, and integrations with tools like SAP Discovery and ServiceNow accelerate the path from unknown to actionable insight.
  • Connect applications to business capabilities to reveal which modernization decisions will have the greatest strategic impact, not just the easiest technical fix.

Evaluate and prioritize with confidence

  • Go beyond gut feel. The 6R framework (Rehost, Replatform, Rearchitect, Repurchase, Retire, Retain) gives every application a clear transformation path, and custom calculations can automate the classification based on your data
  • Understand what's connected before you change anything. Interface circle maps and data flow diagrams expose dependencies, while matrix and portfolio reports help you prioritize quick wins and flag high-risk moves.
  • Make decisions that stick. Document and govern architecture decisions directly in SAP LeanIX with Architecture Decision Records, giving review boards and future teams a clear rationale for every choice.
Evaluate and prioritize with confidence
Plan your target architecture and build a roadmap

Plan your target architecture and build a roadmap

  • Move from analysis to action. Use pre-defined transformation templates for common changes like technology upgrades or application decommissions, or create custom transformations tailored to your organization's specific architectural needs, each automatically linked to all affected applications and components
  • Structure complex modernization programs as a hierarchy of initiatives, from an overarching transformation program down to domain - or region-specific projects, with full visibility into milestones and dependencies.
  • Keep architecture planning connected to delivery. Native integrations with Jira and SAP Cloud ALM ensure your roadmap stays in sync with project execution.

Easily execute transformations and document changes

  • See the impact before you commit. Visualize how planned transformations will reshape your application landscape using landscape reports and circle maps with built-in time sliders.

  • Execute at scale. The Transformations Explorer gives you a centralized view of all planned changes. Execute individually or in bulk, with all modeled relationships and impacts activated automatically.
  • Keep your architecture repository current. As changes are executed, your as-is landscape updates with a single click, so your data stays trustworthy for the next planning cycle.

Use-Case-App-Mod-Track-progress-and-report-to-stakeholders

Track progress and report to stakeholders

  • Tell the modernization story with data. Build custom dash boards that bring together landscape views, portfolio analysis, and initiative roadmaps, tailored to what each stakeholder group needs to see.

  • Stay on top of what matters. A dedicated KPI dashboard tracks risk, complexity, cost impact, and cloud readiness in one place. Making it easy to spot when things go off track.
  • Give leadership a single view of the big picture. The Architecture Executive Dashboard provides a high-level, drillable overview of modernization progress from TIME assessment status to cloud migration completion.
