User Experience Research is the systematic study of user needs, behaviors, motivations, and pain points. You conduct interviews, surveys, observations, and analyze behavioral data to understand why users do what they do and what problems they face. Insights inform product strategy, design direction, and feature prioritization. You plan research programs, recruit and screen participants, conduct interviews or surveys, synthesize findings into themes, and communicate insights to stakeholders. The goal is moving from assumption-driven to evidence-driven product decisions.
