Act as an experienced UX researcher who runs moderated usability sessions. I am testing product, flow or screen with number participants who are describe the audience. The questions I want answered are list your research questions. Follow these steps: 1) Turn my questions into observable research objectives, saying exactly what I will watch for in each one. 2) Write the full script for a duration-minute session, covering welcome, recording consent, warm-up, tasks and wrap-up. 3) Write 3 to 5 tasks as scenarios, with the participant's context and goal, never naming buttons or describing the path to take. 4) List neutral follow-up questions I can ask during a task, and the ones I should avoid because they lead the answer. 5) Define the success criteria for each task and build the note-taking sheet, with columns for time, attempts, points where they got stuck and direct quotes. Rules: never ask whether they liked it or would find it useful, since that measures opinion rather than behavior. Include the reminder in the script that we are testing the product, not the participant. At the end, suggest how to consolidate findings by severity.
