Käytettävyyskokeilu

Käytettävyyskokeilu, often translated as usability testing, is a method for evaluating a product's usability by observing real users interacting with it. The primary goal is to identify problems and areas for improvement in the design, ensuring the product is easy to learn, efficient to use, and satisfying for the target audience.

During a usability test, participants are given specific tasks to complete using the product, which could be a website, application, software, or physical device. Researchers observe their actions, listen to their comments, and sometimes ask follow-up questions to understand their thought processes, difficulties, and overall experience. This hands-on approach provides direct feedback on how users actually engage with the product, rather than relying on assumptions.

Key aspects measured in usability testing include task success rates, time taken to complete tasks, number of errors made, and user satisfaction. By identifying these metrics, designers and developers can pinpoint specific pain points in the user journey. This allows for data-driven design decisions, leading to a more intuitive and user-friendly final product. Usability testing is an iterative process, often conducted at various stages of development to refine the design before launch and even after release to address any emerging issues.
