Even though the practice of integrating evaluative features into the artifact has long been applied in commercially available software, it is still under represented in IS community. This paper presents a design theory for built-in evaluation support. We seek to incorporate the idea of 'the self-evaluating artifact' into the design science research. We are aware of the challenges in designing built-in evaluation features in socio-technical systems and take this issue into consideration in our framework. While the theory draws from the literature on evaluation in DSR, we also provide an expository instantiation of the theory demonstrating a built-in evaluation support mechanism designed and used in DSR research in the Swedish healthcare sector.
