The document describes a user prototype test method to get early feedback on concepts from users before fully developing them. The key steps are: 1) Create quick, low-fidelity mockups or prototypes of a concept in 2-3 versions using methods like role plays or storyboards. 2) Invite users to test and interact with the prototypes, observing how they use it and what challenges they face. 3) Capture structured feedback from users on what's working well, opportunities for improvement, questions, and new ideas using a feedback grid. The goal is to fail early and improve the concept.
