Usability testing serves three main purposes. Firstly, it helps in discovering problems that users may encounter while interacting with a product or interface. By observing and analyzing user behavior, usability testing uncovers any obstacles or issues that hinder a smooth user experience, enabling companies to make necessary improvements and optimize user satisfaction.
Secondly, usability testing allows for comparisons against benchmarks. By establishing a set of predefined standards or objectives, companies can assess the effectiveness and efficiency of their product or interface. Usability testing measures how well a design meets these benchmarks, providing valuable insights to refine and enhance the usability of the product.
Lastly, usability testing aids in comparing against other interfaces. By testing a product against similar competitors' designs, companies can gain a better understanding of where their product stands in terms of usability and user experience. This evaluation allows for learning from competitor successes and failures, enabling companies to stay competitive and continuously improve their own product.
