Goal-Oriented RE for E-Services

Current research in service-oriented computing (SoC) is mainly about technology standards for SoC and the design of software components that implement these standards. In this paper we investigate the problem of requirements engineering (RE) for SoC. We propose a framework for goaloriented RE for e-services that identifies patterns in service provisioning and shows how to compose business models from them. Based on an analysis of 19 business models for e-intermediaries we identified 10 intermediation service patterns and their goals, and show how we can compose new business models from those patterns in a goal-oriented way. We represent the service patterns using value models, which are models that show which value exchanges business patterns engage in. We conclude the paper with a discussion of how this approach can be extended to include business process patterns to perform the services, and software components that support these processes.
