Document Summary
Determines whether a site is easy to use by target audience. Designer may know principles of good design, but end user is the one who really counts: you can"t tell the user how to use your site. Particularly important because designer has little or no control over end user"s situation. With paper mock-ups before site is implemented. After the "real" prototype has been created, but before the final system is rolled out. Experts in interface design and usability: look for violations of usability guidelines. Members of the target audience: look for problems related to the knowledge domain and task completion. Experts are more attuned to general usability issues but less to the knowledge domain. Steps in testing: recruit representative audience members, provide a setting, collect the data, evaluate and incorporate the feedback. Provide a suitable reward for incentive: reward depends on status of user and their interest in the process.
