Thereby, the process of integrating diverse user data poses several challenges. The aim of our research project AndProtect is to develop a usable tool that provides users a risk evaluation of their apps. Therefore, we captured requirements of smartphone users and applied diverse methods and questioning techniques. For this, we conducted a survey (N = 227) and a user experience assessment (N = 31). Thereby, challenges with regard to the feasibility of user requirements, the consideration of the frequency of responses, and contradictory statements occurred. As a result, we present how we dealt with these challenges and purpose strategies for the requirements integration. Our purposes can guide other researchers, since different methods, techniques and samples commonly used in a user-centered process. Moreover, the discussion on this article could support the identification of new approaches to integrate diverse user data.enqualitativequantitativeuser research methodsuser experiencemobile application10.18420/in2017_2351617-5468
