"What features do you want?" feels like the obvious question to ask your users. It's also one of the least useful. People happily tick every box, nobody has to make a trade-off, and you end up with a wish list where everything is a top priority.
Here are four better ways to find out what to build next.
Why “what feature do you want?” fails
Wanting something costs nothing, so a direct feature question gives you no signal about priority. Worse, users tend to propose solutions rather than describe their actual problem.
Ask about problems, not features
Shift the question from the solution to the problem. Instead of asking which feature to build, ask what's getting in their way. You'll uncover the real need — and often a better solution than the one they'd have requested.
Importance × satisfaction: the gap map
For each item, ask two questions: how important is it, and how satisfied are you with it today? Plot the two and a clear picture appears. The corner that's high-importance but low-satisfaction is your roadmap — that's where users hurt and you're not delivering yet.
Don't pour effort into things people already love, or things they don't care about. Build where the gap between importance and satisfaction is widest.
Kano, in plain English
The Kano model sorts features into three useful buckets. It stops you from polishing delighters while a must-have is still broken.
Ranking forces the trade-off
When you do ask directly, don't use checkboxes — use a ranking question. Making people drag options into order forces the very trade-off a checkbox lets them dodge, so you learn what they'd give up.
Combine it with usage data
Surveys tell you what people say; your product analytics tell you what they do. Prioritize where the two agree — a highly-wanted, high-gap feature that also shows up in usage data is a safe bet. Where they disagree, dig deeper before you build.
Where to start
Replace “which feature?” with a problem question.
Run an importance × satisfaction survey and map the gaps.
Use ranking, not checkboxes, when you ask directly.
Cross-check the top candidates against your usage data.
💡 A quick start
Survio's ranking and rating questions make the gap map and prioritization surveys quick to build. Pair this with "How to Run Usability Testing Surveys" in this collection.
