Supporting context — Aware service evolution with a process management requirements model

Context-aware services concern with reasoning about surrounding context and adapting services accordingly have attracted much research attention during recent years, whereas the relation between context-aware service evolution and requirements evolution has not caught many researchers' eye. Conventionally, requirements engineering particularly focuses on users' needs, we argue though that developers' needs must be discovered in the course of services evolution process. In this case, the connection between context-aware service evolution and requirements evolution will be fully discovered, in turn, it will better the guide as to how to evolve exiting context-aware services in order to benefit the best from current service assets. To build this connection, we propose a process management requirements model with requirements elicitation techniques to support context-aware service evolution. A medium sized open source case study is carried out for evaluation.
