Prototyping & Testing

Test Before You Build

The most expensive design mistake is building the wrong thing. Interactive prototypes allow you to test your product with real users before investing in development. A well-built prototype in Figma looks and feels like the real product — users interact with it naturally, revealing usability issues, navigation confusion, and missing features before they become expensive development problems.

Prototype Fidelity Levels

Low-Fidelity Prototypes

Clickable wireframes that test information architecture, user flows, and content hierarchy. Used in early discovery to validate product structure. Quick to build, quick to change. We use these to answer the question: can users find what they need?

High-Fidelity Prototypes

Pixel-perfect interactive mockups with real content, animations, and realistic interactions. Used to validate the complete user experience before development. We use these to answer the question: do users enjoy using this product?

Usability Testing Protocol

5 participants per round (identifies approximately 85% of usability issues). Task-based testing with realistic scenarios. Think-aloud protocol to understand user reasoning. Sessions recorded and analyzed. Key findings documented with video evidence and specific design recommendations.

What We Measure

Task completion rate, time on task, error rate, System Usability Scale (SUS) score, and qualitative feedback. These metrics provide objective evidence of design quality — not just opinions, but measurable usability performance.

Deliverables

Interactive Figma prototype with realistic flows and transitions. Usability test plan, recordings, and analysis report. Prioritized list of design improvements based on evidence. From 164,70 EUR per prototype + testing cycle.
