Your question is Measuring Post-Launch Feature Success. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you evaluate the success of a new feature after launch for Liftoff? Explain how you would define the feature's intended outcome, select a primary KPI, and distinguish adoption from actual user or business value. Describe the data, comparison approach, segmentation, guardrails, and decision criteria you would use to recommend scaling, iterating, or removing the feature.
