How to answer measure success of feature with uncertain user adoption in PM interview

When asked how to measure success for a feature with unpredictable adoption, shift focus from volume to behavioral signals. Define early indicators like discovery rate, first-use latency, and completion of key actions. Segment usage by user type to identify early adopters and detect patterns. Use funnel analysis to spot drop-offs and qualitative follow-ups to understand hesitation. Emphasize phased evaluation—learning before scaling. Success isn’t mass adoption but validated utility for a meaningful cohort and clear insight into barriers for others.
