Frequent questions about UX/UI
Do you also do design only, without development?
Yes - concept, prototype and design system are handed over cleanly documented to your team. We are strongest, though, when design and development come from one team.
How do you test designs?
With clickable prototypes and real users: short test rounds, clear tasks, honest findings. Five tests before the build beat one expensive mistake after.
What is a design system - and do I need one?
A library of reusable components with clear rules. From the second product or the third developer on it saves real money - before that a clean UI kit is often enough.
