PECULIARITIES OF UI TESTING

Abstract

The modern development of information technologies significantly affects the formation of demand and causes the appearance of digital products. For any digital product to be successful, a user-centric approach must be taken. User experience research is a key component of this development approach. UX research is the process of finding out how people interpret and use products and services. It is used everywhere from websites to mobile phones, consumer electronics, medical equipment, banking, and more. In UX design, research is a fundamental part of solving relevant problems. Today, when all existing processes are greatly accelerated, users quickly lose loyalty to a product, because they know that there are many other options and do not hesitate to look for them, so a bad user experience with an application, site or product in general can mean the end of the interaction. UX research is very useful for developing a product strategy and algorithmizing solutions that would meet the needs of users. The issues of optimal choice of research methods, both quantitative and qualitative are considered. Both the methods themselves, such as the interview method, focus groups, card sorting, tree testing, preference assessment, eyetracking, proof of concept, A/B testing, and their areas of application are examined. The advantages and disadvantages of the methods, as well as their features, are considered. The method of analyzing hierarchies to calculate criteria such as efficiency, price, time, and sample size was used. Based on the conducted analysis, it was established that the most important criterion when choosing a research method is its effectiveness. Further calculation of the weighted average scores for each decision option allowed to identify the best research methods and provide recommendations for their effective use at different stages of digital product development. Thus, the optimal choice of testing method can significantly improve the quality of the user interface.
