How to answer measure success of a feature with no clear KPI in PM interview

Start by defining the feature’s core intent—what user behavior or business problem it solves. Break down success into proxy metrics that reflect engagement, adoption, or downstream impact. Use qualitative signals like user feedback or support tickets if quantitative data is sparse. Frame early success around learning velocity: how quickly insights are generated to guide iteration. Avoid vanity metrics; focus on signals that inform next steps.
