How to turn Architecture Transparency into Hard Savings

One of the biggest blind spots I see in large enterprises isn’t technology — it’s cost visibility.

Most organisations know what applications they have. Very few can confidently say what those applications truly cost, how that cost is distributed, or which ones are quietly eroding value.

That’s why the new Application Total Cost of Ownership (TCO) Extension in SAP LeanIX is an important step forward for enterprises serious about optimising their systems.

Why TCO visibility matters now

As organisations move through:

  • S/4HANA transformations
  • Application rationalisation programs
  • Cost optimisation mandates
  • Architecture simplification initiatives

Without trusted, structured cost data embedded into the architecture model, decisions become subjective. This extension changes that.

What the Application TCO Extension delivers

At its core, this extension provides a lightweight but trusted cost backbone across your application landscape.

It introduces:

  • Dedicated cost fields (maintenance, licensing, support)
  • Calculated total cost of ownership
  • Allocation of TCO across business capabilities and organisations
  • New landscape reports for cost-driven analysis
  • Executive KPIs for dashboards — built for decision-makers, not architects

An important clarification

SAP LeanIX is not a cost management or IT finance system. The objective is not accounting-level accuracy.

The goal is to establish:

  • A cost model that is easy to maintain
  • Data that is consistent and comparable
  • A level of accuracy that is meaningful for enterprise architecture decisions

This is exactly the right balance. Architecture doesn’t need perfect numbers — it needs decision-grade insight.

Fresh vs Stale Data and updates

Cost data must be actively maintained to remain credible. Organisations should either assign clear ownership for each cost object, with periodic reviews enforced through automated quality-seal break mechanisms, or integrate directly with an external cost management platform such as Apptio to ensure ongoing accuracy and currency.
