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.

Enterprise Architecture Management (EAM) is a prominent discipline for purposefully guiding the complex, coevolutionary business-IT relationships in organizations. Means to realize such guidance are, among others, mechanisms to coordinate heterogeneous and potentially conflicting stakeholder concerns. Yet, organizations face challenges to successfully leverage their EAM initiatives, often as a result of coordination mechanisms that only reach specific stakeholders or selected contexts.In the paper at hand, we aim at introducing coordination as a research lens for analyzing and designing EAM approaches. To this end, we substantiate the abstract notion of coordination through its underlying formal and informal mechanisms, which are implemented by artifacts, as well as through artifact modalities in an analysis framework. For illustrative purposes, we apply the developed analysis framework to The Open Group Architecture Framework (TOGAF). We find informal mechanisms (lateral relations, communication, and socialization) comparably underrepresented, which limits not only coordination effects but may also limit the success of the overall EAM approach. Our findings call for an extended and more comprehensive perspective on coordination in EAM, motivating the complementarity of informal mechanisms as an avenue for future research.

Information systems analysis and design (ISAD) ensures the design of information systems (IS) in line with the requirements of a business environment. Since ISAD approaches follow the currently dominant logic of business, the rise of a new and thriving business logic may require revisiting and advancing extant ISAD approaches and techniques. One of the prevailing debates in marketing research is the paradigmatic shift from a goods-dominant (G-D) to a service-dominant (S-D) logic of business. The cornerstone of this reorientation is the concept of value cocreation emphasizing joint value creation among a variety of actors within a business network. With the aim of introducing value co-creation as a new discourse to ISAD research, this research note argues that (1) the lens of S-D logic with its core concept of value co-creation provides a novel perspective to ISAD. The authors also assert that (2) value co-creation-informed IS design realizes the paradigmatic shift from G-D to S-D logic. Building on this mutual relationship between value co-creation and ISAD, they propose a research agenda and discuss the ISAD artifacts that prospective research may target.

Simulations provide a useful methodological approach for studying the behavior of complex socio-technical information systems (IS), in which humans and IT artefacts interact to process information. However, the use of simulations is relatively new in IS research and the current presence and impact of simulation-based studies is still limited. Furthermore, simulation-based research is quite different from other approaches, making it difficult to position and evaluate adequately. Therefore, this paper first analyses the particularities of simulation-based IS research that distinguish this approach from other, more conventional approaches. Based on this analysis, we then conduct a structured literature review of the status quo of simulation-based IS research, to understand how IS researchers currently employ simulation. In combination, a comparison of the theoretical potential of simulation-based research in IS with its current status quo enables us to derive a set of propositions, which provide guidance for prospective simulationbased research.

Abstract. Enterprise Architecture (EA), which has been approached by both academia and industry, is considered comprising not only architectural representations, but also principles guiding architecture's design and evolution. Even though the concept of EA principles has been defined as the integral part of EA, the number of publications on this subject is very limited and only a few organizations use EA principles to manage their EA endeavors. In order to critically assess the current state of research and identify research gaps in EA principles, we focus on four general aspects of theoretical contributions in IS. By applying these aspects to EA principles, we outline future research directions in EA principles nature, adoption, practices, and impact.

Perspectives in organizations differ to which extent information systems (IS) should be tailored towards local (e.g., business unit) needs or toward organization-wide, global goals (e.g., synergies, integration). For contributing to overall IS performance success, the harmonization of different perspectives becomes essential. While many scholars have highlighted the role of IS management approaches, institutional studies argue that harmonization is not solely the result of managerial action, but a consequence of institutional pressures that guide organizational decision-making. In the paper at hand, we follow the call for adopting institutional theory on the intra-organizational level of analysis and study the logic of attaining harmonization along institutional pressures. By means of a revelatory case study, we find harmonization attained in a dynamic interplay between different institutional pressures. Mimetic pressures influence normative pressures, which in turn influence coercive pressures. Our findings as well as our implications for enterprise engineering guide prospective research in studying the attainment of harmonization through an institutional lens.
