This document discusses guerrilla research methods for mobile UX testing. It recommends testing early and often using low-fidelity prototypes like paper prototypes. Participants should be real users performing realistic scenarios. Observers should focus on expectations, behaviors and interactions rather than opinions. The document provides an example assignment where participants test a mobile tax app using a paper prototype or HTML demo. Roles like moderator and observer are defined. The goal is to understand how people interact with the app and identify areas for improvement.
