Käytettävyyskysely

Käytettävyyskysely, known in English as a usability questionnaire, is a research tool used to gather user feedback on the ease of use and overall experience of a product, system, or service. It typically consists of a series of questions designed to elicit subjective opinions from users about their interaction with the subject under study. These questions can range from rating scales, where users indicate their agreement or satisfaction with statements, to open-ended questions that allow for detailed qualitative responses.

The primary purpose of a käytettävyyskysely is to identify usability issues, measure user satisfaction, and understand user perceptions. By collecting this data, designers, developers, and product managers can gain valuable insights into how users interact with their creations, what aspects are working well, and what areas require improvement. This feedback is crucial for iterative design processes and for ensuring that a product meets the needs and expectations of its target audience.

Commonly, käytettävyyskyselyt are administered after users have had an opportunity to interact with the system or product. This can be during or after a usability testing session, or after a period of using a live product. The data collected from these questionnaires can be analyzed quantitatively, for example, by calculating average scores, or qualitatively, by categorizing and interpreting open-ended responses. The results help inform design decisions, prioritize changes, and ultimately lead to more user-friendly and effective solutions.
