Testing in Production

Testing in production means trying changes on your live site or app in a safe and controlled way. You start small, watch closely, and expand only when things look healthy. Tools like feature flags, canary releases, and rollbacks make this approach practical. The benefit is faster learning with less delay between idea and impact. Example: Turn on a new search experience for 5% of traffic, monitor errors and speed, then grow to 50% if all looks good.
