TOWARDS REQUIREMENTS ELICITATION IN SERVICE-ORIENTED BUSINESS NETWORKS USING VALUE AND GOAL MODELLING

Due to the contemporary trends towards increased focus on core competences and outsourcing of non-core activities, enterprises are forming strategic alliances and building business networks. This often requires cross enterprise interoperability and integration of their information systems, leading to widespread adoption of Service Oriented Architectures (SOA). In this paper we present an approach to guide the development and evolution of service-oriented business networks. Our approach combines value models and goal models, where the former are used to represent and analyse the economic sustainability of a business network and the latter are used to represent and analyse the goals of the participants within the business network. Systematic guidelines are proposed to derive a goal model from a value model. In addition, a preliminary discussion is presented on how to refine goals and operationalize goals as services rooted in a SOA. The approach is illustrated using an example of a business network in the electricity sector.
