Design Science Research (DSR) has been practiced for decades and is an accepted and wide spread research approach in the discipline of Information Systems (IS). DSR is The huge popularity of DSR has lead to that DSR has become the research paradigm within the IS discipline. One purpose of DSR is to guide design and evaluation of artifacts. However, popular DSR methodologies lack empirical evidence based on primary data. This lack is also recognized by several authors of DSR methodologies. Using secondary data for answering new questions implies an analytic expansion which means that methodological issues have to be considered. The purpose of this work-in-progress paper is to justify the need of empirically grounded DSR methodologies by using primary data.
