Service-oriented architecture (SOA) is one of the most discussed topics in the information systems (IS) discipline. While most computer scientists agree that the service-oriented paradigm has clear benefits in terms of technical quality attributes, it has been difficult to justify SOA economically. The few studies that have investigated the strategic and economic aspects of SOA are mostly exploratory and lack a more comprehensive framework for understanding the sources of its economic potential. Based on IS and SOA literature, our work goes further in suggesting the SOA economic potential model, which describes the causal relationships between the SOA's style characteristics and value it can provide on the business side. Using this model, we investigate 164 SOA cases published between 2003 and 2008 to explore the economic rationale for adopting SOA. Our findings suggest that SOA's business benefits are currently mainly driven by operational and information technology infrastructural improvements. However, enterprises also realize strategic benefits from SOA; for example, by electronically integrating with their business partners by means of SOA. We use the results of our study to derive propositions and suggest a research model for future studies on SOA's economic potential. © 2010 M.E. Sharpe, Inc.

Dynamic phenomena are key concerns of IS researchers. However, the methodological approaches usually selected to investigate IS phenomena often rely on variance theory. Underlying factor models represent a rather static approach to the phenomenon by focusing on independent and dependent variables and explaining the degree of the relationships between them. Process theory has been suggested to overcome this problem. Process theory provides a complementary, dynamic perspective on IS phenomena by explaining how independent and dependent variables are linked in terms of event sequences. Although applying both approaches provides more complete pictures of IS phenomena, a lack of research methods focusing on process theories may hinder this goal. This article seeks to help closing this gap by examining how case research can be applied to develop process theory. We analyzed IS case research as well as process research literature and consolidated inputs from both sources toward a single methodology. The results highlight that the development of process theory benefits from a consistent methodology and quality measures that have been suggested in general case research. However, we also found that each step requires specific consideration of process theory characteristics in order to develop rigorous process theory.

The emergence of the Internet as a global communication infrastructure has dramatically reduced interaction costs within and across organizations, with significant impact on inter-organizational relationships, vertical industry structures, and markets. More recently, service-oriented architectures (SOA) and Web services have introduced the next paradigm shift and foster the idea of dynamic business networks with quick connect and disconnect relationships. However, little research has systematically analyzed how companies leverage SOA to improve their inter-organizational relationships and reshape their business networks. In addition, the mature research stream on inter-organizational information systems (IOS) has not yet sufficiently considered SOA. In order to close this gap, our research seeks to improve the fundamental understanding of how SOA is applied in business networks and how it differs from prior forms of IOS. Using an exploratory research approach, we investigate 33 SOA cases to identify focus areas and patterns of SOA adoption in business networks. Our case analysis builds on a multidimensional classification scheme which we derived from prior literature. While our empirical findings do not confirm all promising propositions related to SOA, they underline the specific contribution of SOA compared to prior forms of IOS. We conclude by suggesting five clusters of SOA adoption in the inter-organizational domain, each of those introducing new aspects in the coordination of distributed business networks. © Institute of Information Management, University of St. Gallen 2010.

Competence-based learning (CBL) is an appropriate approach to systematically develop dwindling human resources. The close interrelation between the knowledge and competence concepts suggests the conjoint development of knowledge management (KM) and CBL. We specifically focus on the question of how KM can support CBL processes. This article describes the potential synergies, as well as KM instruments that can facilitate the implementation of CBL. In conclusion, we introduce our current research projects and propose a research agenda that address the raised research question. © 2012 IEEE.

Recent research endeavors have shown that knowledge sharing improves not only organizational idea development and innovation, but also work performance. In that matter, IS researchers have mostly focused on macro level analyses. We address this by developing a multilevel model for investigating the impact of organizational social web site (SWS) usage on individual and team performance. Our paper addresses this gap by drawing on existing guidelines for multilevel theorizing. We propose that team SWS usage impacts individual and team performance through its improved structural collaboration capabilities. Organizational learning, social capital, and network theories serve as the theoretical basis. Ultimately, we present a multilevel model as the foundation for future empirical research. Our research's contribution lies in the theoretical derivation of a multilevel model. © 2012 IEEE.

Enterprise architecture management (EAM) is acknowledged as a discipline to drive organizational change, to improve IT landscapes' transparency, and to align business and IT. Despite its increasing popularity in practice, many EAM initiatives are confronted with substantial challenges, as demonstrated by the low usage level of enterprise architecture (EA) documentation and enterprise architects' lack of authority, and often fail. This motivates our research, which aims at developing a design theory that may guide organizations to successfully implement EAM. Based on three field studies, we first analyze the issues that arise when implementing EAM in practice. We find that EAM often suffers from being regarded as a separate and parallel initiative, although it needs to be embedded in established management processes and organization. We then suggest a design theory for architecture-driven IT management (ADRIMA) that synthesizes prescriptive knowledge related to embedding EAM practices, artifacts, and roles in the existing IT management processes and organization. By consolidating both IT management and EAM perspectives, our research goes beyond existing EA literature and EA frameworks which describe EAM as a stand-alone management concept focusing on EA models and the EA life cycle. © 2013 Springer-Verlag Berlin Heidelberg.

Today's omnipresence of technology leads to individuals using similar technology inside and outside of organizations. We suggest that the aspects of this technological co-presence might affect technology-induced organizational change processes. We argue that the implications for organizations will require new theories and appropriate methods. Structuration Theory (ST) represents a powerful lens to address the complexities of technological co-presence. Based on Orlikowski's (2000) practice lens, we develop a new lens, which we believe is an appropriate perspective to study this phenomenon. This perspective enables us to include employees as nested entities within organizational boundaries and as individual agents outside organizational boundaries. A case study in an organization using Wild technology is used to study the technological co-presence of an organizational Wild and Wikipedia. We provide preliminary results, which underline our theoretical considerations, and outline future work. © (2011) by the AIS/ICIS Administrative Office.

Project management information systems (PMIS) are an important building block of efficient and effective project management. They have changed considerably in the last decades, starting as mere scheduling applications and now serving as complex systems covering a wide range of project processes and addressing a multitude of stakeholders. Vendors of PMIS frequently claim that these systems yield numerous benefits on the individual, workgroup and organisational level. To date, however, there is no empirical support for this claim. Also, there is still considerable uncertainty with regard to the factors influencing the success of a project management information system. This paper proposes a model for PMIS success based on the revised IS Success Model by DeLone and McLean (2003). We also suggest an accompanying survey instrument which was extensively validated using qualitative interviews, a Q-sorting/item ranking procedure and a quantitatively evaluated pre-test with 45 participants.

From the IT governance point of view, one central project portfolio management task is to ensure that official projects draw upon assigned human resources. However, a common phenomenon is that resources thought to be available often turn out to be actually unavailable. Previous research indicates that numerous unofficial initiatives are a typical cause of this observation. These un-enacted projects are those projects that have not been officially evaluated but do exist although they are not known to a company's project portfolio. The result is that unofficial initiatives compete for scarce resources. Despite these resource issues, previous research has barely investigated unenacted projects. By building on four in-depth case studies, this exploratory study investigates the major drivers of the occurrence of un-enacted projects and their specific characteristics and found a great variety in respect of the type of un-enacted projects and the reasons for them being triggered in organizations.

Social software has recently attracted the attention of organizations. Nowadays organizational social software applications are often bundled within enterprise social software platforms (ESSPs). Given the popularity of social software in the private realm (e.g., Facebook), organizations expect their employees to use the ESSPs in the same frequency right after rollout. However, employees do not always meet this expectation, leading to internal social software platforms that starve for attention. While there is some research investigating users' motives to adopt social software in the private realm, empirical research on social software adoption in an enterprise setting is still scarce. As a step towards closing this research gap, we collected a rich set of qualitative data aiming at investigating the determinants of employees' ESSP usage. Based on theory and the collected qualitative data, this paper proposes a conceptual ESSP adoption model combining the theoretical perspectives of innovation diffusion theory and social capital theory.
