Feature Flag Driven Development - Seamlessly Integrate Feature Flags Into Your SDLC

Learn how to implement Feature Flag Driven Development (FFDD) to seamlessly integrate feature flags into your Software Development Life Cycle in this 24-minute conference talk from CNCF. Discover how feature flags decouple deployment from release, enabling safe rollouts and continuous delivery, while addressing the challenges that emerge at scale including drift between environments, inconsistent definitions, and runtime bugs from undefined or mistyped flags. Explore a real-world case study from one of the largest health systems in the US, where daily releases using feature flags boosted delivery speed but exposed risks due to poor flag hygiene. Master the FFDD workflow that treats feature flags as first-class citizens, built on the CNCF OpenFeature specification and tools like the OpenFeature CLI to eliminate manual coordination, reduce errors, and enable GitOps-driven promotion. Follow along with a comprehensive demonstration of the complete FFDD flow including defining flags, generating type-safe code, validating in CI, syncing flags, and promoting safely across environments using GitHub Actions.
