Insights from practice indicate that the crucial aspect regarding the success of IT standards is their implementation and enforcement. Thus, we derive the following research question: Which factors influence the intention to accept and use organizational IT standards on an individual level? Embedded as a deductive study in the acceptance research stream, we also conducted a supplementary field study incorporating nine interviews to answer this question. Our main result is a conceptual model covering the most influential factors regarding the acceptance of organizational IT standards. Our work has a twofold contribution: First, we advance the research field on organizational IT standards by establishing links to the field of acceptance research and offering explanations for individual acceptance of those standards. Second, our developed model serves as a basis for managing organizational IT standardization.

The resulting lack of methodology usage by individuals fails to deliver the expected advantages of better quality, control, less time, and less effort in IS development projects. We analyse the technical as well as non-technical aspects of an individual's use of ISDM methodologies, in order to enable organisations to engineer those that meet the needs of actual users and are actually used by them in a productive manner. We construct a conceptual model, based upon which, we posit that: technical methodology attributes such as relative advantage, complexity, compatibility, demonstrability, visibility, triability, and reinventability influence an individual's methodology usage behaviour. We also propose that the strengths of these relationships depend on non-technical, deeply rooted psychological needs of the people.

Die erste Einsicht lautet: Die Entwicklung elektronischer Lehr-Lernangebote darf nicht, wie lange geschehen, allein vom Primat der Technik getragen werden. Die zweite Einsicht lautet: Methodisch-Didaktische Ansätze sind eine tragende Säule bei der Entwicklung von E-Learning-Angeboten. E-Learning soll Unternehmen die Möglichkeit bieten, die Kosten der Weiterbildung durch kürzere Abwesenheit vom Arbeitsplatz sowie Einsparung von Reisekosten zu minimieren. Just-in Time-Learning soll es dem Arbeitnehmer ermöglichen, aktuelle Wissenslücken individuell und schnell zu schließen. Diese Vorteile, um nur einige Beispiele zu nennen, werden immer wieder mit dem E-Learning verbunden (siehe bspw. [LaPä02, S. 17ff.; HaOt02, S. 21ff.; Witt95]). An der systematischen und umfassenden Beantwortung der Frage allerdings, wie

Hence, organizational managers must identify and apply user influence tactics (UIT), to ensure adequate and appropriate use of these methodologies within their organizations.

The research described in this paper is based on a combination of interviews and a survey in two phases and aims to investigate the organizational practices in dealing with this risk, and how it is influenced by the adopted project execution strategy with regard to process model selection decisions.

This research points out the expectations, the realized benefits and -more importantly -the major differences between them. For this purpose, it compares ex-ante expectations of their respective users and compares them in turn with ex-post realised benefits. The results of the study are based on the statements made by 234 participants in an online survey conducted in 2006. Generally, standards are only rarely used in project management in Germany and Switzerland. And if standards are indeed used, they are rarely used ''as is"; in fact they are usually modified or adapted before application. Moreover, it can be observed that most participants expect consistent communication in the projects and better process quality to be the primary benefits of standards. However, it is often impossible to realize expected benefits. Benefits are offset by deficiencies, such as the lack of acceptance, administrational overheads and associated costs. Based on the results of this study, recommendations for standard-giving organizations and standard-applying organizations are put forward.

They no longer focus on scheduling and resource management alone. Instead, they have become comprehensive systems that support the entire life-cycle of projects, project programs, and project portfolios. In this context, project-oriented organizations are facing a new challenge: the design, implementation, and operation of project management information systems have become increasingly complex. Numerous processes have to be considered, diverse stakeholder interests taken into account, and corresponding software systems selected. The reference information model (Ref-Mod PM ) presented in this article addresses this challenge and aims to accelerate the set-up of project information systems. RefMod PM was developed with the help of 13 domain experts from German and Swiss enterprises. Furthermore, it is based on an analysis of 28 commercial project management software systems. RefMod PM has already been applied in several projects and is the basis of the forthcoming German DIN norm for a standardized project management data model.

The model, initially based on a literature review, was thereafter refined by means of empirical evidence collected in the automotive distribution sector and the banking industry. The authors suggest that the economic potential of this new information systems architecture depends on its fundamental characteristics as well as on the individual business models and IT strategies of the companies wishing to use SOA. In addition to presenting a comprehensive model, this paper also presents selected examples from the fieldwork that illustrate how SOA can be used to create economic potential in the considered industries.

Since SOA concepts and technology are maturing, companies have started to engage in projects that will fundamentally transform IS landscapes over the next decade. While the growing body of SOA research is mostly technology-oriented, there is a need to review the current state of research in light of the strategic, organizational, and managerial issues associated with SOA implementation. This paper profiles SOA and Web services research since 2000 with a focus on practices, adoption, and impact. Drawing on a sample of 175 papers in academic journals and conference proceedings, we establish transparency of the current state of SOA research. Our analysis finds that the science base for SOA research from an IS perspective is still under construction thereby reflecting the novelty of the underlying technologies. We conclude that business aspects remain underserved and derive a number of recommendations for the IS community on how to proceed with SOA research.

PROMONT models project management specifications from a number of sources, most notably the upcoming DIN 69901 model for the exchange of project data. As a reference ontology it helps to build a common understanding of project related terms and methods thus facilitating the management of projects conducted in dynamic virtual environments. It is especially well suited for cross-enterprise project related business processes such as integration management, communication and controlling. A distributed project scenario is used to illustrate how a project plan is broken down for individual partners, and how activities are coordinated in a heterogeneous group.
