The case for research
Most teams file user research under "nice to have." The evidence — and the biggest names in tech — say it's the highest-leverage money in the building. Here's the case, in plain terms, with the receipts. Even if you've never quite known what a UX researcher does, start here.
"We don't have budget for research" is almost always the wrong frame.
A forced "Register" step before checkout was killing first-time buyers. Research swapped it for a "Continue" button. +45% conversions, +$300M in the first year. One label, found by watching real users.
Jared Spool / Center Centre ↗An engineer's idea sat shelved for months until someone finally A/B-tested it: combine the ad's second line into the headline. +12% revenue — ~$100M a year from a change nobody thought was worth building.
Harvard Business Review ↗Amazon tested deliberately slowing pages: every 100ms of delay cost ~1% of sales. Google found half a second of added latency dropped search traffic 20%. The detail you can't feel, abandoning carts at scale.
Greg Linden (Amazon) / Google ↗Early on, the founders suspected bad listing photos — not pricing — were the real barrier. They went door to door shooting professional photos. The insight became a program that still lifts bookings ~19% and host earnings ~21%.
Airbnb ↗Usability testing is one tool inside it. The job is bigger: making sure effort lands on the right problem.
But that's just my opinion, right?
Decades of study across business and product converge on the same finding: teams that take user understanding seriously outperform the ones that don't — and most of what gets built is never even used.

Nielsen Norman Group — Usability ROI ↗NN/g has been running the numbers longer than almost anyone — and the takeaway is blunt: a little structured research, early, catches most of what would otherwise cost you later.

Nielsen Norman Group — UX Metrics & ROI ↗of a product's usability problems are exposed by testing with just five users — you don't need a big, expensive study to find what's actually broken.
Jakob Nielsen — Nielsen Norman Group ↗Translation: the cheapest study you'll ever run still catches most of the problem. Skipping it is the expensive choice.
A short, curated list of the people and ideas I actually draw on. Read top to bottom, they tell one story: find the assumption a bet depends on, and test it before it gets expensive.
The cheapest study still catches most of the problem. Rigor isn't a budget line item.
Research is a practical team sport — not ceremony you bolt on at the end to feel safe.
The facts you need aren't in the conference room — they're with the people you're building for.
Treat every plan as a stack of assumptions, and learn which are true before betting the quarter on them.
Map the assumptions a bet depends on, then test the riskiest first. The de-risk discipline in one field guide — and the closest thing there is to my own operating manual.
Make discovery a weekly habit, not a phase — and tie every idea back to a real, observed opportunity.
The biggest risk isn't building it wrong — it's building something nobody wants. Discovery is how you find out first.
Why you watch what people do, not just what they say — the gap between the two is where the money quietly leaks.
Same through-line as everything I ship: the riskiest assumption, found and tested while it's still cheap.
Theory's cheap. Does any of it pay?
The case studies above prove the discipline. These are mine — the same work, in rooms I was in. Real metrics; client specifics kept confidential.
