Usability testing is a technique of evaluating the user experience of a web product or service by testing it with representative users. It is an approach to identify issues that users may encounter when using the product and to collect feedback about how to enhance the product's usability.
Over the years, with increasing competitors, organizations are actively researching and spending on understanding usability. And, merely design and content aren't adequate; the software or website's engaging, intuitive, and responsive user experience, which an average person can use to achieve specific goals, has become important too.
