Usability Testing

Definition

Usability testing is the measurement of the usability of a product or service. The definition from usability.gov succinctly describes the process.

In a usability test, representative users try to do typical tasks with the product, while observers, including the development staff, watch, listen, and take notes. The product can be a Web site, Web application, or any other product. It does not have to be a finished product. You should be testing prototypes from early paper-based stages through fully functional later stages.

Note that the process of usability testing differs from usability engineering, which is concerned the research and design of usable products, rather than testing a product's usability.


Recruiting

You will need to find usability test participants. To source them, you have different options ranging from selecting from your pool of current users, to recruiting them yourself or through an outside service.
