Abstract: Agent-Based Models (ABMs) have long served to study self-adaptive systems and the emergence of population-wide patterns from simple rules applied to individuals. Recently, the rules for each agent have been expressed using a Fuzzy Cognitive Map (FCM), which is elicited from a subject-matter expert. This provides a transparent and participatory process to externalize the `mental model' of an expert and directly embed it into agents. However, software technology has been lacking to support such hybrid ABM/FCM models at scale, which has drastically limited the scope of applications and the ability of researchers to study emergent phenomena over large populations. In this paper, we designed and implemented the first open-source library that automatically accelerates ABM/FCM models by leveraging the CUDA cores available in a Graphical Processing Unit. We demonstrate the correctness and scaling of our library on a case study as well as across different networks representing agent interactions. Collapse

Abstract: Different from previous cloud adoption studies that focus on the benefits and concerns of cloud computing from a technology point of view, this study takes a deeper look at two additional firm-specific forces that could better explain firms’ cloud adoption trajectory and dilemma: Path dependency and Institutional forces. Path dependency theory argues that if a firm has invested intensively in traditional IT, it may be more capable of adopting and utilizing new IT since it has accumulated knowledge. However, the firm could also be trapped in its previous path and reluctant to migrate to cloud to avoid sunk costs and switching costs. On the other hand, institutional theory provides an external view and posit that a firm facing more institutional forces from its trading community will have more incentives, as well as pressure, to adopt cloud. We developed a cloud adoption model that features benefits, concerns, path dependency, and institutional forces as prominent antecedents to understand their competing and complementary effects, and empirically tested the proposed model using 177 firms. The results show that, path dependence is indeed an important factor affecting firms’ cloud adoption behaviors; a firm with a better IT position and more satisfying IT outsourcing experiences will have greater cloud adoption intention. Institutional forces do not directly affect cloud adoption intention. Instead, institutional forces increase perceived benefits, through which, indirectly influence cloud adoption intention. The findings delineate the trajectory and dilemma that firms face when migrating to cloud and provide insights to cloud vendors in choosing their target market. Collapse

Abstract: The internet of things (IoT) and digital platforms have offered industrial companies new opportunities to compete against digital platform-native companies. To succeed in this competition, industry incumbents must learn to extend their traditional product and service business through platforms. However, extant research has focused primarily on the ability of platform owners to govern mature platforms for innovation but has largely ignored how industry incumbents can build these capabilities internally during the establishment of their platform ecosystems as part of larger transformational journeys. To address this gap, we conduct a multiple case study of three incumbent organizations, drawing on a dynamic capability lens. We identify 11 practical microfoundations of sensing, seizing, and reconfiguring dynamic capabilities that aided three incumbents in establishing their IoT platform ecosystems. Besides the transformational activities, our findings contribute to the literature on platform establishment through three IoT-related shifts that deviate from known digital platform paradigms.

Abstract: We suggest an emergent change framework for enterprise architecture. Drawing on Leavitt’s Change Model of Organizations, our framework focusses on socio-technical changes in tasks, structures, actors, and technologies. By applying the framework to a medium-sized company from the media industry and drawing on a relatively unique panel data set (2014, 2016, 2018), we demonstrate the amount of emergent changes and confirm three patterns of change. These findings help to advance the study of change and its propagation across different components of an enterprise over time. Collapse

Abstract: In software development vendor contexts, asset specificity is commonly thought to lead to vendor lock-in. But asset specificity in the context of software development is not one thing. It could involve specific functional assets, specific knowledge assets, and specific technical assets. Based on Transaction cost economics (TCE) and IT outsourcing literature, we theorize about the ways that different forms of software development asset specificity interact to influence lock-in in software vendor relationships. We develop three hypotheses about (1) the moderating effect of knowledge asset specificity on the relationship between functional asset specificity and lock-in; (2) the moderating effect of technical asset specificity on the relationship between functional asset specificity and lock-in; and (3) the moderating effect of software popularity on the relationship between knowledge asset specificity and lock-in.

Abstract: This article focuses on the determinants influencing organizational adoption of vendor-supported open-source software applications or open-source office applications (OSOAs). We employed a plural investigation with QUAL/QUAN sequence. Empirical analysis of the data obtained from 257 IT managers identified various technological, organizational, and environmental determinants that influence the OSOA adoption either positively or negatively. These findings offer valuable insights for IT managers and OSOA vendors which can guide them in formulating appropriate strategies for OSOA adoption. Collapse

Abstract: Herding in open platform adoption decisions appears to prevail even when the systems adopted represent high risks with enterprise-wide impact. We present a model of organizational open platform adoption that integrates six different theoretical mechanisms based on a technology-organization-environment framework that drives herding: network effect benefits, new platform benefits, new platform risk, organizational learning, mimetic pressures, and competitive pressures. To find which mechanisms work significantly in organizational IT decision-making in accordance with IT diffusion and rival precedence, we empirically test the model by splitting the samples according to the proportion of rivals that have already adopted innovations. The empirical results demonstrate that among the six herding mechanisms, new platform risk and organizational learning drives herding in the earlier stage of diffusion and new platform benefits and competitive pressure drives herding in the later stage of diffusion. The results imply that organizations react conservatively to new platforms when they perceive less platform diffusion. However, as diffusion increases, organizations react more strategically to maintain competitive parity with rivals by imitating rival decisions. Collapse

Abstract: The incentive for IT service and infrastructure providers to participate in cloud ecosystems lies in the generation of rents that cannot be generated individually by either alliance partner – i.e. the opportunity to co-create value. The IS literature on cloud ecosystems is scarce and provides only limited insights on value co-creation in cloud ecosystems. Based on an in-depth case study, we develop a framework which serves as an organizing and simplifying device explaining how value is co-created in different types of cloud ecosystems and what success factors of these different types of cloud ecosystems are.

Abstract: Cloud computing is drawing attention from both practitioners and researchers, and its adoption among organizations is on the rise. The focus has mainly been on minimizing fixed IT costs and using the IT resource flexibility offered by the cloud. However, the promise of cloud computing is much greater. As a disruptive technology, it enables innovative new services and business models that decrease time to market, create operational efficiencies and engage customers and citizens in new ways. However, we are still in the early days of cloud computing, and, for organizations to exploit the full potential, we need knowledge of the potential applications and pitfalls of cloud computing. Maturity models provide effective methods for organizations to assess, evaluate, and benchmark their capabilities as bases for developing roadmaps for improving weaknesses. Adopting the business-IT maturity model by Pearlson & Saunders (2007) as analytical framework, we synthesize the existing literature, identify levels of cloud computing benefits, and establish propositions for practice in terms of how to realize these benefits.

Abstract: a b s t r a c tCloud computing is a new information technology (IT) paradigm that promises to revolutionize traditional IT delivery through reduced costs, greater elasticity, and ubiquitous access. On the surface, adopting cloud computing requires a firm to address many of the same concerns they face in adopting any enterprise IT. However, cloud technologies also offer new pricing and deployment strategies that are unavailable in traditional enterprise solutions. It is unclear how previous research frameworks of enterprise IT adoption relate to these new adoption strategies. To bridge this gap in the literature, our study uses the technology-organization-environment (TOE) framework of innovation diffusion theory to develop a cloud service adoption model that deals with not only adoption intention, but also pricing mechanisms and deployment models. Our research model has been empirically tested using 200 Taiwanese firms. We found that: (1) Cloud adoption is still at its initial stage, since the adoption rates are very low; (2) the perceived benefits, business concerns, and IT capability within the TOE framework are significant determinants of cloud computing adoption, while external pressure is not; (3) firms with greater IT capability tend to choose the pay-as-you-go pricing mechanism; (4) business concern is the most important factor influencing the choice of deployment model, with higher concerns leading to private deployment options.
