monday.com's engineering team shares how a feature flags replacement project evolved into a full internal product called Ignite, now used by 600+ developers across 400 services. The post covers the build-vs-buy decision, adoption strategy, the introduction of a guided release wizard that codified release best practices, and the friction of migrating teams away from legacy behavior. Key lessons include using ADRs for decision documentation, involving heavy users early, and embedding guidelines directly into the tool's workflow rather than relying on documentation.
