From Developer Pain to Impact: Establishing Large Scale Refactoring at SAP

This session follows our journey at SAP from developer frustration to establishing the large scale refactoring capability. We’ll share how we moved from grassroots discovery and community workshops to building a robust business case for automation. Learn how we leveraged an InnerSource model to bridge the gap between central technology teams and product units, effectively “paving the road” for seamless upgrades, migrations, and recurring code changes.
