Over the past few years, enterprise architecture management (EAM) has become increasingly popular in academia and in practice. One reason for this is that organizations seek to make use of various benefits that have been associated with EAM. However, researchers have stressed that EAM research has mainly focused on prescriptive frameworks and methodologies, whereas these concepts and associated impacts and outcomes have seen little generalization and verification to date. In this paper we explore this claim. Based on a comprehensive literature analysis, we found that prescriptive research does indeed dominate the field. However, we also found that few researchers have analyzed and generalized EAM phenomena, whereas the share of contributions to explanation and prediction is negligibly small. We summarize common EAM processes as well as impact and outcome factors that have emerged from this research and show to what extent the relationship between these components has thus far been explained.

Organizations invest considerable resources in the development and implementation of IT project management (IT PM) methodologies to increase productivity and quality as well as to save time, effort, and resources. However, such methodologies are often rejected outright by users. Our research analyzes the determinants of individual usage behavior in order to enable organizations to engineer IT PM methodologies that not only provide strategic benefits but also meet the needs of actual users. The existing literature, especially Triandis' Theory of Interpersonal Behavior as well as initial case study results from a number of organizations are used to construct a conceptual model. This research model includes four dimensions: a) Value, b) workgroup influence, c) self-beliefs, and d) organizational characteristics, which are all considered to positively influence the development of the intention to use a methodology. Additionally, we find that the effect of intentions on actual usage can be weakened by an individual's automatic behavior such as habits. Source

Widely discussed in the mass media, Web 2.0, or social software, has also drawn the attention of researchers, developing into a whole new research area. With Web 2.0's further development, corporations aim to adopt its technologies and transfer its benefits, such as enhanced collaboration and knowledge sharing, to their organizations. Whether any of these benefits also apply in an organizational context and whether there are further, still uncovered, benefits remains unclear. Furthermore, research in this area is still in its early stages, thus hampering progress towards qualitative and quantitative models that could provide answers. In order to encourage further progress in this area, we reviewed the existing research on corporate blogging and identified 24 articles that investigate the topic. Using the framework by Ives et al. [18], we categorized the articles for further analysis. By means of process theory, we build a conceptual model and identify the antecedents and consequences of internal corporate weblog usage. Our findings suggest that usage is driven by organizational culture, as well as by attitudes towards blogging. In addition, the benefits of weblog usage are centered on community benefits. © 2010 IEEE. Source

Supply Chain Risk Management has become a key concern for organizations, which is even further emphasized by the current economic and financial crisis. Against this background, this paper investigates successful approaches and experiences by companies in dealing with this new reality, especially as it concerns the supply side. Using in-depth case studies conducted among eight European enterprises, we develop a set of propositions about how companies manage supply risks in financial crises, highlight how their risk management approaches have shifted, and illustrate how they are related to Enterprise Risk Management. Our framework is further differentiated based on whether firms are predominantly engaged in manufacturing or services - a factor influencing how supply chain risk is managed. Transaction cost economics serves as our main theoretical anchor. By rigorously grounding our research in both theory and empirical evidence, we provide valuable insight for both academia and practice. © 2011 Elsevier B.V. Source

Widely discussed in the media, Web 2.0 systems have drawn the attention of corporations, many of which now seek to adopt Web 2.0 technologies and transfer its benefits to their organizations. Organizations often struggle with the adoption of information systems, and Web 2.0 systems are certainly no exception. As an empirical foundation, we studied three organizations that successfully adopted Web 2.0 systems. We conducted a narrative analysis of the case study material to produce a process theory for Web 2.0 system adoption. Finally, we compare it to the enterprise system experience cycle of Markus and Tanis (2000). Our results indicate that the adoption of Web 2.0 systems differs from larger enterprise system adoption projects. This is rooted in the lower implementation and maintenance costs as well as lower technical complexity of Web 2.0 systems. Furthermore, its voluntary characteristics lead to an adoption process that focuses mainly on convincing users of its benefits. Source
