This document provides guidance on conducting lean UX customer discovery. It advises talking to potential users to understand where a product might fit in their work or life, what problems it could solve, and how and when it might be used. Key recommendations include identifying target users and goals before conversations, listening more than talking, capturing observations, and collecting artifacts. The document suggests spending time with users early and often to create a conversation rather than interrogation and maintain an open mind. It cautions against asking about desired features or theoretical usage without understanding user needs. Suggestions are given for finding users to speak with.
