Service-oriented modeling and analysis is a promising approach to manage context-aware cooperation among organizations belonging to the same value chain. Following this approach, a value chain is modeled as a composition of services provided by different partners and coordinated in a way that their interactions can be reorganized according to changes in the environment. However, so far, most of the research work in this area has been focused on the design of architectures handling service discovery, compatibility and orchestration. Little attention has been given to the specification and verification of context-aware composition of services during the requirement engineering process. The goal of this paper is to fill this gap through a methodological approach based on the strict coupling between a social and a process model. The methodology is discussed through a simple example.
