Although the role of theories in design research is recognized, we show that little attention has been
paid on how to use theories when designing new artifacts. We introduce design principles as a new
methodological approach to address this problem. Design principles extend the notion of design
rationales that document how a design decision emerged. We extend the concept of design rationales
by using theoretical hypotheses to support or object to design decisions. At the example of developing
a new conceptual modeling grammar we demonstrate two main benefits of using design principles.
First, the link between theory and design decision enables the design researcher to reason about the
resulting behavior of the IT artifact prior to instantiation. Second, design principles allow deducing
empirically testable hypotheses to foster the rigorous evaluation of IT artifacts.
