Episode 17: An Enterprise Architects view on Clean Core - Michael Sokollek

Guest:
• Michael Sokollek - Chief Enterprise Architect - SAP SE
Host:
• Alexander Greb - Consulting Director - cbs corporate business solutions
• Johannes Langguth - Head of Business Transformation and Architecture - SAP SE

Today we dive past the buzzwords to treat Clean Core as an attitude and a practical operating model—from strategy to execution. We bust the “back-to-standard only” myth, map the five dimensions (processes, extensibility, data, integrations, operations), and show how governance and the right toolchain turn ERP from a cluttered basement into a system you can actually change.
You’ll learn:
• Why Clean Core is a spectrum (keep clean and get clean), not a binary state.
• How to run fit-to-standard with process deviation management and business-case-backed exceptions.
• Where partners, toolchains (incl. Signavio & EA content), and RISE architects fit in.
• How to align capabilities and custom code to decide what truly differentiates.
• The real risk of shadow IT—and how to prevent it with transparency and cadence.
If you’re staring at years of modifications, stuck on an S/4HANA move, or just want upgrades without nightmares, this episode gives you the guardrails, mindset, and first steps to get from talking to doing.
