Engineering That Works: Inside GitHub’s System Success Playbook

In this episode of Code at Scale, we unpack the GitHub Engineering System Success Playbook (ESSP)—a practical, metrics-driven framework for building high-performing engineering organizations. GitHub’s ESSP reframes engineering success around the dynamic interplay of quality, velocity, and developer happiness, emphasizing that sustainable improvement comes not from isolated metrics but from system-level thinking.

We explore GitHub’s three-step improvement process—identify, evaluate, implement—and dig into the 12 core metrics across four zones (including Copilot satisfaction and AI leverage). We also highlight why leading vs. lagging indicators matter, how to avoid toxic gamification, and how to turn common engineering antipatterns into learning opportunities. Whether you're scaling a dev team or transforming engineering culture, this episode gives you the blueprint to do it with intention, impact, and empathy.
