Reconciling Requirements and Implementation via Reengineering for Context-Aware Service Evolution

In modern software development, software requirements and implementation are not always reconciled. This leads to difficulties for evolution tasks in future. Specifically, for modern context-aware systems, changes in stakeholders´ requirements disclose that existing implementation is insufficient to meet the new requirements due to the limitations of the traditional techniques. In this paper, we propose a context-aware requirements elicitation approach to reconcile the gap between software requirements and implementation for context-aware service evolution based on a novel reengineering framework approach. To validate our approach, we carry out a case study of a medium sized open-source location-aware legacy system.
