approche orientée but pour le développement de systèmes à base de services

The connectivity generated by the Internet is opening opportunities of services composition. As a consequence, organisations are forming online alliances in order to deliver integrated value-added services. However, due to the lack of methodologies and tools, the development of such composite service across organisations is usually ad-hoc and poses problems especially in the identification, composition and orchestration issues. In this paper, we propose a goal driven approach to understand the needs of different organisations for a new added-value composite service and to model the cooperative process supporting this service provision in a declarative, goal driven manner. The goal model called Map, is then used for service identification, distribution and orchestration. The paper presents the approach and illustrates it with an E-Pension cooperative service.
