Kujunditest

Kujunditest is an Estonian term for the systematic testing and evaluation of design concepts, products, or interfaces. It covers practices aimed at assessing usability, accessibility, aesthetics, and overall effectiveness of a design.

The practice typically involves planning and conducting experiments, recruiting participants, and collecting qualitative and quantitative data to inform design decisions. Common methods include usability testing, heuristic evaluation, A/B testing, card sorting, and user surveys, often using clickable prototypes or mockups.

The process generally follows stages: define objectives, develop tasks, observe and record behavior, analyze findings, and report recommendations for iteration. Metrics such as task success rate, time on task, error rate, System Usability Scale (SUS), and Net Promoter Score (NPS) are used to quantify results.

Applications span user interface design, product design, graphic design, web design, and architecture. Kujunditest emphasizes user-centered design and early feedback to catch usability and accessibility issues before final production, helping reduce costly changes later.

History and related fields: The concept grew with the rise of human-centered design and UX research from the late 20th century onward. Related terms include usability testing, user research, prototyping, and design validation.
