Structure That Makes Sense to Users
Card sorting and tree testing for information architecture.
The Problem
You are designing or redesigning navigation. Categories, labels, menu structure. You want it to match how users actually think, not how your org chart looks.
Users can't find what they're looking for, but you don't know why. Guessing at navigation labels and structures is expensive to fix after launch. Internal teams organize information by how they work, not how users search. You end up with navigation that makes sense to you but confuses everyone else.
The Solution
We run card sorting to discover how users group concepts, and tree testing to validate if they can find what they need. Data-driven IA decisions, not opinion-based debates.
Information architecture that matches user mental models. Navigation that works on first try.
What You'll Achieve
- Deep understanding of user needs and motivations
- Transcripts and highlight clips for stakeholder sharing
- Synthesized themes and patterns
- Actionable insights, not just raw data

Real feedback from teams we've worked with
Busch Labs/RUF have been an amazing partner for my team and THQ Nordic when it comes to qualitative studies for our video game projects. We were struggling to find partners that were able to adapt to our rapidly changing requirements and short timelines, but Busch Labs continuously went above and beyond our expectations. This is true for recruiting, play sessions, as well as reporting. On top of that, they also helped us strengthen our own internal knowledge and processes when it comes to UX. Marc and his team are very unique, and I strongly recommend them to anybody who has UX-related needs.
Frank Kofler
QA & UX Manager
Working with Busch Labs on usability research for our mobile inspection solution was extremely valuable. The user testing helped us identify key improvements and simplify the guidance, making the overall experience much more intuitive. We also saw a clear improvement in performance, as users now better understand how to use the solution as intended. Marc was great to work with! Very responsive, flexible to our needs, and able to recruit the right users for our specific use case.
Lucie Papelier
Product Manager
Working with Marc & his team is amazing — he is very client- & human-centric, and makes the impossible happen when it comes to deadlines, finding a panel, supporting the research design, etc. He immersed himself in the topic, and supported our project with outstanding engagement, delivering results on time, with deep, actionable insights.
