Design a usability study — research questions, methodology, participant criteria, metrics, and facilitation guide. Use when planning the study as a whole. For writing the task scenarios inside it, use `test-scenario` (prototyping-testing).

AI-generated overview

Designs a usability test plan covering research questions, methodology, participants, tasks, metrics and facilitation.

What it does
This skill produces a ready-to-use usability test plan for evaluating designs and prototypes. It defines research objectives, then lays out research questions, methodology, participant screening and sample size, task scenarios with success criteria, metrics, a facilitation guide, data collection and an analysis plan. It also includes a pilot test checklist and presents everything in a structured format.
When to use it
Use it when planning a usability study as a whole, before sessions begin. It fits UX research work where the deliverable is the study plan rather than the individual task scenarios.
Requirements
No scripts or special tooling; it is instructions only. It may read user-provided files such as prototypes, designs or personas if supplied.

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

  1. Define objectives: What specific questions should this test answer?
  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.
