How to grow and scale your feature management process

Break down feature flags into granular pieces rather than having one large flag controlling multiple features

Implement cleanup processes early - create cleanup tickets and reference them when features are fully rolled out to avoid feature flag debt

Use progressive rollouts starting with small percentages (2-10%) and gradually increase based on monitoring and feedback

Consider different axes for rollouts: by company, user type, region etc. instead of just random percentages

Make testing feature flags painless through dependency injection and making it easy to toggle states locally

Monitor metrics and set up alerting to quickly catch issues during feature rollouts

Treat feature management as part of the release process, not just shipping - includes planning, testing, monitoring and cleanup phases

Balance speed vs safety by using feature flags to enable continuous delivery while controlling risk

Consider using feature flags for performance testing by artificially slowing down load times

Keep feature flag lifecycle clearly defined - particularly for A/B tests which have specific start/end dates compared to general feature flags

Document the purpose and expected lifespan of feature flags to avoid confusion and make cleanup easier

Focus on making testing and validation easy - if testing is painful, people will avoid doing proper validation

Build resilience into the system by having the ability to quickly disable problematic features
