Make Clean Core Actionable
Reduce complexity and enable sustainable innovation without compromising business differentiation.
The challenge
Clean Core Is Not the Elimination of Every Customization
No shared definition, no clear evidence
There's no shared definition of what Clean Core means for the organization, and custom developments lack usage, ownership, or business-value evidence.
Ungoverned extensions and coupling
Extensions are built without clear architecture guardrails, interfaces are tightly coupled and difficult to monitor or change, and data duplication increases complexity.
Rising upgrade cost and stalled governance
Upgrade and release cycles require excessive regression effort, and exceptions accumulate without lifecycle governance.
A successful Clean Core strategy requires explicit choices: what to standardize, what to extend, where to extend it, what to retire, and how to govern future change.
How we help
A Clean Core Strategy Built Around Business Value and Architecture Discipline
We convert Clean Core principles into a target model, prioritized backlog, and sustainable governance system.
Clean Core Baseline
We inventory custom code and modifications, analyze usage and business criticality, assess process deviations, and baseline integration, data, and operations lifecycle maturity.
Target Principles & Architecture
We define standardization principles, an extensibility decision framework, side-by-side and on-stack extension guardrails, and API, data, and analytics architecture principles.
Remediation & Modernization Roadmap
We make retire, retain, remediate, replace, or redesign decisions, prioritize custom code reduction and process standardization, and plan integration decoupling and upgrade-readiness work.
Governance & Controls
We establish the architecture review process, exception and waiver governance, development and release quality gates, and Clean Core KPIs and ownership model.
Enablement & Adoption
We run business and IT alignment workshops, provide developer and architect guidance and reference patterns, and support change communication and continuous improvement.
Business benefits
Build an ERP Core That Can Change Without Losing Control
Faster and Safer Upgrades
Reduce conflicts, regression effort, and uncertainty when adopting new SAP releases and capabilities.
Lower Technical Debt
Retire unused objects, reduce duplication, and prevent new unmanaged complexity.
Greater Innovation Speed
Use governed extension patterns and SAP BTP to introduce capabilities without destabilizing the digital core.
Improved Reliability
Simplify dependencies and operational practices to increase stability and supportability.
Better Architecture Decisions
Give teams clear guardrails for standardization, extension, integration, data, and operations.
Sustainable Transformation
Establish metrics and governance that preserve Clean Core after migration or go-live.

Engagement scenarios
Clean Core Engagements for Different Starting Points
Pre-SAP Cloud ERP Transformation
Use Clean Core to shape scope, target architecture, remediation, and migration decisions before implementation begins.
Brownfield Modernization
Reduce inherited complexity and establish a controlled path from technical conversion to continuous modernization.
RISE with SAP Preparation
Align extensions, integrations, data, and operations with the target cloud model and clean-core expectations.
Post-Go-Live Stabilization
Prevent the new environment from recreating legacy complexity after implementation.
Continuous Clean Core Program
Operate an ongoing governance and improvement model across releases, development, integration, and operations.
