What does usability testing involve?

Usability testing is primarily concerned with evaluating how real users interact with a product or document to identify any issues or areas for improvement. In this context, involving the general public allows for a diverse range of feedback from actual users who represent various demographics and usage scenarios. This broad perspective helps uncover usability problems that may not be evident when only a limited set of users, such as document creators or authors, engage in testing. By collecting insights from the general public, usability testing provides valuable data that can inform refinements to enhance the effectiveness and user-friendliness of the document or product.
