Abstract. Eliciting user requirements at an early stage of software development can safe development time and effort. However, identify requirements for adaptivity, such as inter-individual differences in needs or preferences is not trivial. In this paper we revisit results reported in a previous paper from a methodological point of view. Using an example, we argue that scenarios in combination with structured interviews are not able to adequately identify adaptivity requirements due to reasons inherent to the method, such as the users ’ trust and their ability to anticipate system funtionality. We suggest that more implicit methods must be used at early development phases to obtain unbiased results. 1 User-Centered Design and Adaptivity User-adaptive systems are by definition interactive systems. While there is only little literature on guiding the development of user-adaptive systems from a software engineering point of view (e.g., [8]), user-centered design techniques seem to be an obvious process to be adopted for the design of this kind of systems. The rational of
