Kasutavatustestid, often translated as usability testing, is a method for evaluating the ease of use and learnability of a product or service. It involves observing real users as they attempt to complete tasks with the product. The primary goal is to identify usability problems, gather qualitative and quantitative data, and ultimately improve the user experience.

During a usability test, participants are typically given a set of predefined tasks to perform. Researchers observe their actions, listen to their comments, and may ask follow-up questions. This observation can reveal where users struggle, what causes confusion, and what aspects of the design are successful. The data collected can include task completion rates, time on task, error rates, and subjective satisfaction ratings.

Usability testing can be conducted in various settings, from controlled laboratory environments to naturalistic field studies. It can also be performed remotely or in person, and can involve moderated sessions where a facilitator guides the participant, or unmoderated sessions where participants complete tasks independently. The methods and scope of testing are often tailored to the specific goals of the project and the stage of development.

The insights gained from usability testing are invaluable for designers and developers. They provide concrete evidence of user behavior and preferences, guiding iterative design improvements. By identifying and addressing usability issues early in the development cycle, organizations can reduce the risk of product failure, enhance customer satisfaction, and decrease support costs. It is a critical component of user-centered design.
