Guerrilla Testing

Guerrilla testing is a lightweight, informal usability research method in which researchers approach people in public settings and ask them to spend a few minutes interacting with a product or prototype. It prioritizes speed and accessibility over methodological rigor.

Researchers typically need no recruitment process, no lab setup, and no scheduling. They approach willing participants, briefly explain the study, observe how the participant interacts with the product, ask a few questions, and collect their feedback. Sessions are usually 10–15 minutes long.

Guerrilla testing is best suited for early-stage design validation, quick gut-checks on navigation or layout, and situations where speed matters more than a perfectly representative sample. It is not appropriate for sensitive topics, specialized products requiring domain knowledge, or studies requiring statistical significance.
