Usability Testing

Scope

Covers

• Designing task-based usability studies tied to a specific product decision
• Testing live flows, prototypes, and “faked” implementations (fake door, Wizard of Oz)
• Running moderated sessions (remote or in-person) and capturing high-quality evidence
• Turning findings into a prioritized fix list (including high-ROI microcopy/CTA improvements)

When to use

• “Create a usability test plan and script for .”
• “We need to test a prototype with 5–8 users next week.”
• “Validate a value proposition before building (fake door / Wizard of Oz).”
• “Help me synthesize usability findings into a prioritized backlog.”

When NOT to use

• You need statistically reliable estimates or causal impact (use analytics/experimentation)
• You need open-ended discovery (“what problems do users have?”) without a specific flow to evaluate (use conducting-user-interviews)
