The person(s) requesting the usability test.
The usability evaluation of one version of the product or procedure. An iteration typically consists of several test sessions.
Sometimes also called a prototype, this is a version of the product that contains user interface attributes but very little (if any) coding. Paper screen captures are an example of a mockup.
Mockups are often usability tested because they are inexpensive, contain the essential user-apparent features (and thus provide accurate usability data), and are available early in the design process.
A run-through of a test session conducted before the sessions with the users. This rehearsal is often conducted with a ULab staff member unfamiliar with the product acting as a user, and allows the correction and fine-tuning of test procedures before an actual test session.
The attempt by a user to complete pre-assigned tasks with the product or procedure to be usability tested.
Usability (ISO Definition)
The effectiveness, efficiency, and satisfaction with which specified users achieve specified goals in particular environments.
A facility specifically designed for evaluating the usability of a product. The OCLC Usability Lab contains video, audio, and computer equipment for the archiving and analysis of a user's behavior while using OCLC products.
The person(s) who attempt to complete a set of pre-assigned tasks using the product or procedure. The user matches as closely as possible a set of user characteristics developed by the client and the ULab.
