Usability testing is the process of assessing how well people can use a particular product or interface. This involves having test subjects complete specific tasks while being observed and monitored.

The goal is to identify any areas where users experience difficulty or confusion, so that these can be addressed and corrected.

Usability testing can be conducted on both websites and software applications. It is an important step in ensuring that a product is easy to use and does not cause frustration for the end user.

By identifying potential usability issues early on, it is possible to save time and money down the road by avoiding costly redesigns later on.
