Smart services offer great innovation potential by incorporating digital technologies into non-digital value-creation processes. As smart service innovation poses significant challenges to organizations, existing research has contributed to understanding and addressing this phenomenon by developing various methods, tools, and processes. Yet, the academic community often still fails to bridge the “last mile” and help practitioners apply this knowledge in their specific application contexts. This article outlines how research can empower practitioners by systematically providing methodological knowledge for smart service innovation. We review and contrast existing methodologies and present a conceptual framework for value co-creation through smart service innovation methodologies. In addition, we identify six essential resource types required in these methodologies and propose emergent research avenues to guide future contributions to smart service innovation research.
