Abstract:This study was conducted gain insight into the value of usability testing by both users and experts of a personalized website. Literature study shows that comparing the two methods of research has often been a subject of research. There is no research known that specifically focuses in particular on the value of both research methods regarding personalized websites. The main question of this study is: "What is the value of user testing and testing by experts to improve the usability of personal websites? ". The research in this thesis focuses specifically on the personalized website of Ziggo. As research methods are compared on the one hand heuristic evaluation by experts, in which of the common heuristics of Nielsen are supplemented with heuristics Jameson (heuristics specifically for personalization) and on the other hand as a user test the thinking aloud method supplemented by a post-interview. Six experts and 18 users have participated in the investigation. The results of this study show that adding heuristics specifically aimed at finding problems associated with personalization in an expert examination adds no value in relation to the number of found problems, the average degree of severity of the problems, the thoroughness and validity of this evaluation method. Furthermore, it appears that problems found by experts don’t score higher on the degree of severity of the problems found by users. Within the group of users the target groups don’t contribute in the same degree to the real problems found and the average degree of severity of the, the average of the detected problems difference. In its totality, the results of this study support the hypothesis that the value of heuristic evaluation in the testing of a personalized website is relatively lower than when testing a nonpersonalized website.
