Die dauerhafte Funktionsfähigkeit der IT-Infrastruktur stellt eine notwendige Bedingung für die Verstetigung von E-Learning in den Hochschulen dar. Um die IT-Organisation zu einer Serviceeinrichtung umzubauen, gehört neben der stärkeren Kundenorientierung auch eine Definition der zu erbringenden Services, anhand derer sich auf Basis von Kennzahlen Aussagen über Qualität und Vergleichbarkeit abl...

The rapid evolution of the Internet and its business tools is enabling the transformation and deployment of business processes as highly modular e-services that can be flexibly and dynamically composed to form ad-hoc workflow. This research prepares for the proliferation of automated, Internet-based workflow, by contributing a suite of protocols for self-organizing brokering communities that en...

e-Services represent a new model in the utilization of the network, in which self-contained, modular applications can be described, published, located and dynamically invoked, in a programming language independent way. Research on e-Services spans over many interesting issues, including description, discovery, composition. Our research focuses on automatic composition synthesis. More specifical...

Today's web-based E-services do not handle system failures well. One of the most prominent examples is unintentional purchase of multiple copies of the same item (e.g., a DVD) in an online store. This may happen when the user sees a browser timeout for the final “checkout” (“place order”) request caused by a short outage or overload of the network or the backend servers (typically during peak l...

Nowadays, application of Service Oriented Architecture is increasing rapidly; especially since introduction of distributed electronic services on the web. SOA software has a modular manner and works as a collaboration of independent software components. As a result, e-service approach is sufficient for software with independent components, each of which may be developed by a different company. ...

The convergence of mobile communication and mobile computing technologies opens up new horizons for mobile interaction and mobile working. The use of mobile technology in the government sector not only provides an alternative channel of communication and public service delivery, but more importantly, it can address the mobility of the government itself and in this way transcend the traditional ...

The purpose of this article is to examine the theoretical foundations of e-service quality and develop a conceptual model for it. Even though e-service quality has increasingly attracted the attention of researchers, the existing research in this area is mostly focused on identifying quality dimensions of e-services without any deeper attention to the mechanism behind the quality perception. Th...

User experience (UX) is difficult to quantify and thus more challenging to require and guarantee. It is also difficult to gauge the potential impact on users’ lived experience, especially at the earlier stages of the development life cycle, particularly before hi fidelity prototypes are developed. We believe that the enrolment process is a major hurdle for e-government service adoption and badl...

B2B interaction requires new forms of coordination between participating organizations. Indeed, the main requirement is that the autonomy of each participating partner is preserved during the interaction, guaranteeing at the same time that the overall goals of the common process are reached. Mechanisms for regulating distributed workflow evolution when the workflow is composed of the invocation...

Until recently, the Internet was dominated by web sites and storefronts. We have now entered the next Internet evolution: e-services. E-services are modular, nimble, electronic services that perform work, achieve tasks, or complete transactions. The first step to turn an existing asset or service into an e-service revolves around accessibility. The virtualisation of the service provides communi...
