Usability Testing

Plan and run tests that find usability problems before users hit them in production. Stack-agnostic. Tool-agnostic.

This skill is for testing existing designs or prototypes. For broader discovery research, use ux-research. For conversion testing in production, use cro-optimization.

When to use

Before launching a new flow or major redesign
After a redesign to verify it doesn't introduce new problems
When analytics show drop-off but you don't know why
When customer support tickets pattern around specific UI areas
Pre-launch user validation
Comparing two design directions

When NOT to use

Discovery / generative research (use ux-research)
Live conversion optimization (use cro-optimization)
Mapping the broader experience (use journey-mapping)
Pure quantitative measurement (use analytics-strategy)

Required inputs

The design or prototype to test (functional or near-functional)
Specific tasks users would do
The audience (who should be tested)
Testing infrastructure (moderated tool, unmoderated tool, in-person setup)

The framework: 5 phases

1. Define what to test

Don't test the whole product. Test specific tasks.
