The inner and the outer model in explanatory design theory: the case of designing electronic feedback systems

Both Information Technology (IT) artifacts and design theories are important elements for knowledge capture in design science research in information systems. Building on a rich tradition of constructing and evaluating artifacts, recent design science research has made significant advances toward better understanding the explanatory aspect of design theory. Researchers have stressed the importance of mid-range theories that relate IT artifact features (causes) with measures and goals (effects). Against this background, design theorizing reveals certain commonalities with theorizing in the behavioral science field. In this paper, we explore differences and similarities between theorizing in these areas. We develop a framework that allows for a better understanding of the relationships between manifest design decisions, kernel theory constructs and their evaluation metrics. We identify common issues that arise from conceptual distances between these ideas and show their potential impact on both the design and evaluation of artifacts. The field of electronic feedback systems is used as an illustrative example.
