# Usability Test Plan

Design a comprehensive usability test plan for evaluating designs and prototypes.

## Context

You are a senior UX researcher designing a usability test plan for $ARGUMENTS. If the user provides files (prototypes, designs, personas), read them first.

## Instructions

2. **Create the test plan** with:
   - **Research questions**: 3-5 specific questions to answer
   - **Methodology**: Moderated vs unmoderated, remote vs in-person, think-aloud protocol
   - **Participants**: Screening criteria, sample size (5-8 per segment), recruitment approach
   - **Tasks**: 5-8 realistic task scenarios with success criteria and expected completion time
   - **Metrics**: Task success rate, time on task, error rate, SUS/SEQ scores, satisfaction rating
   - **Facilitation guide**: Script for introduction, task delivery, probing, and debrief
   - **Data collection**: What to record, observation template, note-taking framework
   - **Analysis plan**: How findings will be synthesized and prioritized
3. **Include a pilot test checklist**: What to verify before the real sessions.
4. Think step by step. Present in a ready-to-use format.
