Usability testing is one of the most effective methods of verifying whether the applied solutions are comfortable and understandable for users and whether they translate into the implementation of business goals. This technique is useful for getting rich information about users— their workspace, personal preferences, and habits. Usability testing works best when you need to have in-depth information on how real users interact with your product and what issues they face. It will help you investigate the reasoning behind user behavior In an industry devoted to creating a great experience for people who use products, services, and apps, usability testing is paramount. This type of user research is exceptionally important with new products or new designs. Your in-depth knowledge of, and familiarity with, your website might prevent you from seeing its design or usability issues. When you run a website usability test, users can identify issues with your site that you may have otherwise missed. For example website bugs, missing or broken elements, or an ineffective call to action (CTA). Conducting such a test on a pre-prepared prototype, before submitting the project to programmers for coding, saves time and money. It is easier to change a model than a finished product. A breakdown of the main usability testing methods (includes lab testing, session recordings, card sorting) and when/why you should use them allow to draw conclusions and prepare a report, which is a valuable element, of, e.g. board presentation.
