Five product pages were already live. Not one had ever been tested with customers.
The product detail pages had never been tested with real users.
Design followed internal opinions rather than observed behaviour.
Nobody could prove why conversion was weak. They could only guess.
Two people against a roadmap and against opinions with no evidence behind them.
Research, design, testing and analysis sat with Mirko Fazio and me.
The wider team had limited UX experience, so we had to make the case for both the process and the outcome.
Discussions without an expert basis cost weeks until we could put data on the table.
We replaced opinion with evidence and let users make the decision.
A UEQ study with more than 1,000 participants, including competitor benchmarking.
Selection through MaxDiff analysis instead of gut feeling or hierarchy.
Every version was validated against user feedback and sharpened before going live.
Mirko Fazio and I ran the full process from setup through analysis.

The conversion effect is measurable and proven, not a trend argument.
Five product teams adopted the approach as a shared way of working.


What I take away from it
MaxDiff ended in two weeks a discussion that opinions could have kept open for months.
Discussions without substance now get a deadline and a data basis, not another feedback loop.
Clearly structured comparisons help people decide. They almost always beat long explanatory copy.
With a clearer mandate the redesign could have gone live months earlier. I now clarify that frame before a project starts.
With a well-matched counterpart you can deliver in half the time. I plan for that rather than leaving it to chance.
5 products in 8 months instead of roughly 2 years per product. Conversion up to 3%.
Complete redesign within a strict brand framework. Strong mobile experience, followed by a job offer from the client.
Branding and website live in 6 weeks. Modular, maintainable and managed by the client himself.
