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.
