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 organizational agility. We report a comparative, cross-cultural case study of the implementation of Service Oriented Architectures (SOA) at a Scandinavian bank an...

SUMMARY In this paper, we present two descriptive case studies covering the re-engineering and further evolution of adopting service oriented architecture (SOA) in industry. The first case was carried out for a company in the transport sector with an application portfolio of over 700 systems. The second case study was conducted for an organization in the public sector. The goal of both case stu...

This paper describes and discusses a Plackett-Burman experiment aimed at increasing supermarket sales of a top-selling national magazine. The experiment involved 10 factors relating to in-store advertising and the location of the magazine within the store. We discuss issues including choice of factors, alternative designs, sample-size determination (number of test stores and the length of the t...

Service Oriented Architecture (SOA) is emerging to be the predominant architectural style of choice for many organizations due to the promised agility, flexibility and resilience benefits. However, there are currently few SOA metrics designed to evaluate complexity, effort estimates and health status of SOA solutions. This paper therefore proposes a SOA metrics framework which includes both ser...

The paper proposes a metric based framework for evaluating service oriented architecture. Different models and metrics have been proposed in different perspective for evaluating service oriented architecture, but it has been recognized that the available models and metrics are insufficient. This paper gives a software standard based way to identify measurable attributes to propose metrics. This...

Service-oriented architectures (SOA) offer a conceptual and technical solution for many problems. However, the realization and even more the management of a SOA often remains a very hard task. A continuous evaluation of existing services and service candidates is necessary to implement, maintain and enhance a SOA. This is far from being trivial because of the semantic gap between requirements a...
