This case describes major management and technology issues which arise when designing advanced service-oriented architectures in distributed networked environments used for e-learning. The organization at hand uses a mixed funding model and is preparing for a large expansion of its services and capacity. This case takes place after the initiation of a project and during the design phase where s...

Information and Communication Technology (ICT) has helped to drive increasingly intense global competition. In turn, this intensity increases the need for flexibility and rapid changeability in ICT to support strategies that depend on organisational agility. We report a comparative, cross-cultural case study of the implementation of Service-Oriented Architectures (SOA) at a Scandinavian bank an...

In the context of service-oriented computing, time has been extensively studied in literature. We present a survey on possible problem statements for timed services, and give an overview of state-of-the-art approaches. Thereby we identify which problems are already thoroughly researched and which problems warrant further research.

Despite the growing acceptance of SOA, service-oriented computing remains a computing mechanism to speed-up the design of software applications by assembling ready-made services. We argue that it is difficult for business people to fully benefit of the SOA if it remains at the software level. We propose a move towards a description of services in business terms, i.e. intentions and strategies t...

The energy sector, which has traditionally been an oligarchic closed one, is undergoing major changes at all levels. On the one hand, more and more players are authorized to produce, deal and transport energy (unbundling of the sector), while on the other hand, the traditional energy consumers are now in the position to also produce and trade energy. This new trend can be supported by Service-O...

This document presents the Soability model, which assesses on a strategic level how well an IT environment is able to support an SOA based on Web Services. The model is designed to support the answering of typical questions that decision makers in companies face. By so doing the model addresses a lack of methodological support for stakeholders who need to plan an SOA holistically.
