The core research methods product teams actually use - what each is for, when to use it, and how to run one without a big budget or timeline.

TL;DR: UX research is how design decisions get made based on real user behavior instead of internal opinion. Most teams don't need every method - they need the right method for the specific question they're trying to answer, run at a scope that fits their timeline and budget. This guide covers the core methods, when to use each, and how to run research without a dedicated researcher or a large budget.
UX research is the systematic study of users and their needs, behaviors, and pain points, used to inform design and product decisions with evidence instead of assumption. It spans everything from watching someone use a prototype to analyzing usage data at scale, and it happens both before design starts (generative research, to understand the problem) and after something's built (evaluative research, to test whether the solution works).
Qualitative research (interviews, usability testing) answers "why" - it reveals the reasoning, confusion, and emotion behind user behavior, typically with a small number of participants studied in depth. Quantitative research (analytics, surveys, A/B tests) answers "how many" or "how much" - it reveals patterns at scale but doesn't explain the reasoning behind them. Strong research programs use both: qualitative to understand why something's happening, quantitative to confirm how widespread it is.
| Method | What It's For |
|---|---|
| User interviews | Understanding needs, motivations, and pain points before designing a solution |
| Usability testing | Watching real users attempt tasks to find where a design breaks down |
| Surveys | Gathering quantitative data or sentiment from a larger sample |
| Analytics review | Identifying where users drop off or behave unexpectedly at scale |
| Card sorting | Understanding how users mentally group and categorize information |
| A/B testing | Comparing two design variants against a specific metric at scale |
Match the method to the question, not the other way around. If you don't understand why users are struggling, run interviews or usability tests before jumping to a survey or A/B test - quantitative methods tell you what's happening but rarely why, and designing a fix without knowing why often produces the wrong fix. If you already understand the problem qualitatively and need to know how many users it affects, that's when surveys and analytics earn their place.
Research only creates value when it changes a decision - synthesize findings into clear themes and specific, actionable recommendations, not just a transcript dump. In Elysium's process, research findings get translated into design implications before they're presented, so stakeholders see the "so what" alongside the "what we found," which is what actually drives a decision rather than just informing one.
UX research doesn't require a dedicated researcher or a large budget to be valuable - it requires matching the right method to the right question and actually acting on what you learn. Start small, use the users and data you already have access to, and build the habit of testing assumptions before committing significant design or engineering time to them.
