The term "usability testing" refers to the process of evaluating a product or service by putting it to the test with real people. Participants will typically complete everyday activities during a test while observers observe, listen, and take notes. The purpose is to find any usability issues, collect qualitative and quantitative data, and assess how satisfied the participants are with the product. To conduct a successful usability test, you must first create a robust test plan then recruit participants, before analysing and reporting your results. Usability testing allows designers and developers to spot issues before they are coded. The earlier errors are found and corrected, the less costly the remedies will be in terms of both staff time and potential schedule disruption.
