Why rough works
The roughness isn’t a limitation - it’s doing something important. When something looks unfinished, users are more honest. They’ll tell you the flow doesn’t make sense, or that they’d never look there for that button. Show them a polished design and they’ll comment on the font choice. Lo-fi also signals internally that nothing is decided yet. A pixel-perfect mockup in a stakeholder meeting implies finality. A hand-drawn sketch invites challenge - which is exactly what you want in early discovery 💡What lo-fi is best for
- Exploring multiple concepts fast - sketch three different approaches to the same problem in an afternoon, test directional preference with users
- Validating structure and flow - does the information architecture make sense? Can users find their way through the journey?
- Early-stage problem framing - before the solution is defined, lo-fi helps visualise the problem space
- Internal alignment - getting a team pointing in the same direction before investing in design
