Clean Core
Challenges and Strategic Considerations for Modern Enterprise Architecture.Breaking the cycle of technical debt.
The Strategic Imperative
The traditional model of deep customization has generated a "vicious cycle of technical debt" that stifles innovation.
Intensive Customization
Adaptation of the core to legacy processes.
Costly Updates
Every new version requires re-validating all custom code.
Innovation Brake
Resources diverted to maintenance instead of value.
The Solution: Clean Core Philosophy

Keep the S/4HANA core standard and decouple innovations in SAP BTP.
Fundamental Pillars
Clear principles to ensure the integrity and agility of the SAP environment in the long term.
Side-by-Side Extensibility
Prioritize SAP BTP for complex developments. Decouple customizations from the core to facilitate updates.
Standard Processes
Adapt business to software, not the other way around. Maximize the value of SAP best practices.
Standard APIs
Secure and versioned communication. A "contract" that protects integrations from future changes.

Impact and Quantifiable Benefits
Clean Core adoption is not just technical, it's a transformation with clear ROI.
Strategic Migration Paths
| Approach | Cost | Duration | Innovation | Description |
|---|---|---|---|---|
| Brownfield | Medium | Medium | Low | Technical conversion. Maintains history and processes. |
| Greenfield | High | High | High | New implementation. Total redesign and native Clean Core. |
| Hybrid | Medium-High | Medium-High | Medium-High | Selective. Combines the best of both worlds. |

Recommended Action Plan
To move from analysis to action, we propose an initial phase of structured diagnosis.
Exhaustive Diagnosis
Analysis of current processes, applications, and technical debt.
Systems Plan
Definition of target architecture and prioritization of initiatives.
Business Cases
Qualitative and quantitative justification (ROI) for each initiative.
