Information systems (IS) increasingly expand actor-to-actor networks beyond their temporal, organizational, and spatial boundaries. In such networks and through digital technology, IS enable distributed economic and social actors to not only exchange but also integrate their resources in materializing value co-creation processes. To account for such IS-enabled value co-creation processes in multi-actor settings, this research gives rise to the phenomenon of digital value co-creation networks (DVNs). In designing DVNs, it is not only necessary to consider underpinning value co-creation processes, but also the characteristics of the business environments in which DVNs evolve. To this end, our study guides the design of DVNs through employing servicedominant logic, a theoretical lens that conceptualizes value co-creation as well as business environments. Through an iterative research process, this study derives design requirements and design principles for DVNs, and eventually discusses how these design principles can be illustrated by expository design features for DVNs.Drawing on and integrating into extant value co-creation and S-D logic research, we give rise to the phenomenon of DVNs, briefly synthesize DVNs' conceptual constituents (i.e., digital infrastructure, value co-creation, and actor-to-actor networks), and introduce S-D logic as employed kernel theory. Digital value co-creation networksStill, little light has been shed on how actors engage in contexts of dyadic and physical resource integration (Breidbach

Crossing the line: overcoming knowledge boundaries in enterprise transformation Teaser Enterprise transformations are fundamental changes in an organization. To succeed, shared understanding between many diverse stakeholder groups like program managers or business managers is essential. We analyze which properties of enterprise architecture models are beneficial for creating shared understanding. We assess the differences between stakeholders through the lens of knowledge boundaries, and enterprise architecture models through the lens of boundary objects. We develop and empirically test a research model. Our findings show which boundary object properties contribute to a syntactic, semantic and pragmatic capacity needed to overcome the respective knowledge boundary.

Enterprise architecture management (EAM) has become a widely acknowledged approach for guiding the continuous change of increasingly complex organizations. While methods and models for describing and analyzing enterprise architectures (EA) have been extensively discussed, principles guiding an EA's design and evolution are hardly covered in existing research. The paper at hand therefore analyzes the mechanisms of EA principles (EAP), that is EAP grounding, EAP management, and EAP guidance and their effects on EA consistency and EAM utility. Specifically we aim at understanding the role of organizational culture for the mechanisms and effects of EAP. Based on empirical data we find that all relations describing EAP mechanisms and their effects are significantly moderated by organizational culture. Based on our findings we give recommendations on how to deal with selected design decisions when introducing and developing EA principles in an organization.

According to Kuhn, science and progress are strongly interrelated. In this paper, we define criteria of progress for design theories. A broad analysis of the literature on information systems design science reveals that there is no consensus on the criteria of progress for design theories. We therefore analyze different concepts of progress for natural science theories. Based on well-founded criteria stemming from the philosophy of science and referring to natural science theories, we develop a set of criteria of progress for design theories. In summary, our analysis results in six criteria of progress for design theories: A design theory is partially progressive compared to another if it is ceteris paribus (1) more useful, (2) internally more consistent, (3) externally more consistent, (4) more general, (5) simpler, or (6) more fruitful of further research. Although the measurement of these criteria is not the focus of this paper, the problem of measurement cannot be totally neglected. We therefore discuss different methods for measuring the criteria based on different concepts of truth: the correspondence theory of truth, the coherence theory of truth, and the consensus theory of truth. We finally show the applicability of the criteria with an example.
