User research is the systematic study of the people who use — or will use — a product: what they need, how they behave, and in what context. The point is to ground UX design in evidence instead of the team’s hunches.
It is not a one-off kickoff workshop. Qualitative methods (interviews, usability tests, watching someone in their real setting) explain why. Quantitative methods (analytics, heatmaps, A/B tests, surveys) measure what and how many. Together they feed user personas, user journeys, and prototypes — and they should continue after launch, when real traffic shows where the product actually breaks.
A real-life example of user research
An Atlanta clinic assumes patients want a full “health portal.” Five interviews later, the pattern is different: people want to text to reschedule and see the copay before they book. Building the portal would have been expensive guessing. A short research pass is cheaper than a feature nobody asked for.
You don’t need a lab. A handful of honest conversations plus watching a user flow fail in the wild beats a 40-page slide deck. Start with What Is User Research?.
