This is a well-known meme that sums up how dispensable design can become without user testing. We updated it according to our understanding. Source: @vinniequinn, twitterAs mentioned in the beginning, customers today have very high demands on digital products. Outstanding usability can therefore decide whether a customer opts for product A or product B.Against this background, it is essential that UX designers do not create functionalities and user interfaces on the basis of their own assumptions, but rather collect research results and findings, aggregate them and carry out user tests.
