usability-testing
Conduct effective usability testing using frameworks from 11 product leaders.
- Choose the right test fidelity: fake doors and Wizard of Oz tests for concept validation, prototypes for design feedback, production testing for optimization
- Small sample sizes (10 random users) reveal core friction points; direct observation of user behavior uncovers needs that surveys miss
- Test multiple design options simultaneously to measure relative performance, not single designs in isolation
- Bring cross-functional teams (PMs, engineers, designers) into live sessions to build shared understanding and overcome creator bias
- Progress through testing stages from internal fish fooding to early adopter programs to alphas, increasing confidence iteratively before full launch
Usability Testing
Help the user conduct effective usability testing using frameworks and insights from 11 product leaders.
How to Help
When the user asks for help with usability testing:
- Clarify the goal - Determine if they're validating a concept, finding friction points, or optimizing conversion
- Choose the right fidelity - Help them select between Wizard of Oz tests, fake doors, prototypes, or production testing
- Design the test - Guide them on recruiting users, creating scenarios, and what to observe
- Plan for iteration - Discuss how findings will flow back into the product development process
Core Principles
Fake it before you build it
Itamar Gilad: "Initially you fake it - fake door test, smoke test, Wizard of Oz tests. We showed the tabbed inbox working to people, but it wasn't really Gmail, it was just a facade." Validate core value propositions before writing production code using faked versions where humans perform the automated task behind the scenes.
Small samples reveal big friction
