How to answer metrics for limited reach high impact feature in PM interview

For features serving a narrow but critical user segment, focus on outcome over output metrics. Measure success through depth of impact—e.g., time saved, error reduction, or satisfaction spike—within the affected cohort. Use qualitative insights alongside quantitative data to demonstrate value. Since broad metrics like DAU may not reflect impact, isolate the user group and track behavioral shifts, escalation drops, or workflow completion rates. Justify investment by linking the feature to system-wide efficiency or risk mitigation.
