Decathlon x Datadog: The Marathon Prep. of Observability

How do you establish reliability standards and build alignment across a global engineering organization? Decathlon operates localized e-commerce stores in 54 countries, more than 1,900 physical stores worldwide, and hundreds of engineering projects supporting its business at scale. As teams grew, inconsistent SLAs and fragmented monitoring practices made it increasingly difficult to maintain a unified approach to reliability. In this DASH session, Gilles Di Guglielmo, Senior Staff Engineer, and Thomas Parle, Engineering Manager, share how Decathlon built and deployed its observability maturity model. Learn how the team codified observability into five progressive levels—from foundational logging, SLIs, and SLOs to distributed tracing and automated anomaly detection—and used the framework to drive adoption across e-commerce teams. Watch for practical insights on implementing observability at scale, aligning teams around common reliability standards, and building a monitoring strategy that evolves from basic logging to end-to-end user journey visibility.
