Usability inspection is the name for a set of methods where an evaluator inspects a user interface. This is in contrast to usability testing where the usability of the interface is evaluated by testing it on real users. Usability inspections can generally be used early in the development process by evaluating prototypes or specifications for the system that can't be tested on users. Usability inspection methods are generally considered to be cheaper to implement than testing on users.
Usability inspection methods include:
- Cognitive walkthrough (task-specific)
- Heuristic evaluation (holistic)
- Pluralistic walkthrough
Famous quotes containing the word inspection:
“Thus the orb he roamed
With narrow search, and with inspection deep
Considered every creature, which of all
Most opportune might serve his wiles, and found
The serpent subtlest beast of all the field.”
—John Milton (1608–1674)
