Prototype Walkthrough
Does this make sense at a glance?
This test catches navigation problems, dead ends, and wrong assumptions at the prototype stage — when fixing them is fast and cheap, not after you've built the real thing.
See what this costs →Why It Matters
Fixing a flow problem after development costs ten times more than fixing it in a prototype. But most teams skip prototype testing because it feels "too early."
Here's what you miss when you skip it:
- Users expect a different flow than the one you've designed — and get lost immediately
- Critical steps feel obvious to your team but confuse everyone else
- Dead ends and missing navigation paths only surface after development
- Stakeholders disagree on the user journey but nobody has user evidence to resolve it
Every flow problem you catch in a prototype is a development cycle you don't waste.
Prototype Walkthrough gives you real user navigation data before you write a single line of production code.
What You'll Learn
Navigation Instinct
See where users naturally expect to go next — and whether your flow matches their mental model.
Expectation Alignment
Discover whether each screen delivers what users expected to find — or whether the journey feels disjointed.
Confusion Points
Identify exact moments where users hesitate, backtrack, or express uncertainty about what to do next.
Missing Elements
Find out what users look for but can't find — the gaps in your prototype that would become expensive gaps in production.
What This Test Does Not Measure
This is not a full usability test on a finished product. It evaluates flow and navigation at the prototype stage — not task completion performance on production software.
Looking for that instead? Try a Task-Based Usability Test.
Frequently Asked Questions
Any tool that produces a shareable link — Figma, InVision, Adobe XD, Marvel, Framer, or even a series of linked images. As long as testers can click through a flow, it works. See our dedicated Figma prototype testing page for details.
It doesn't need to look polished. What matters is that the key flow is clickable and navigable. Low-fidelity wireframes work just as well as high-fidelity mockups — the test is about navigation, not visual design.
A full usability test measures task completion, error rates, and efficiency on a working product. A Prototype Walkthrough tests navigation flow and user expectations at an earlier stage — when changes are still cheap to make. See our Task-Based Usability Test page for details.
We recommend at least 8–10 testers to identify clear navigation patterns. With fewer, individual navigation styles can obscure the real flow issues. For complex flows, 15+ testers give stronger signals. See our guide on how many testers you need for details.
Yes, but we recommend focusing on one primary flow per test for the clearest results. If you have multiple flows, running separate tests gives you cleaner data for each journey.
Most tests complete within 24–48 hours. Each tester spends around 8–12 minutes walking through the prototype and providing commentary, with multiple testers running in parallel.
