A Reengineering Approach to Reconciling Requirements and Implementation for Context - Aware Web Services Systems
… software development, the gap between software requirements and implementation is not always conciliated. Typically, for Web services-based context-aware systems, reconciling this gap is even harder. The aim of this research is to explore how software reengineering can facilitate the …

Visual language representation for use case evolution and traceability
… to assist non-technical stakeholders involved in requirements engineering with a comprehensible method for managing changing requirements within a specific domain. An important part of managing evolving requirements over time is to maintain a temporal ordering of the changes and to support …

Requirements Documents Evolution and Synchronization with Activities in the Refined Requirements Generation Model
Over the past few years the real importance of requirements engineering has surfaced; hence, much research is now being directed towards generating quality requirements. However, the existing requirements generation models do not sufficiently stress the importance of identifying intermediate …

Efficient Reasoning with Constrained Goal Models
… used in Computer Science to represent software requirements, business objectives, and design qualities. Existing goal modelling techniques, however, have shown limitations of expressiveness and/or tractability in coping with complex real-world problems. In this work, we exploit advances in …

Managing the Uncertainty of the Evolution of Requirements Models
Evolution is an inevitable phenomenon during the life time of a long-lived software systems due to the dynamic of their working environment. Software systems thus need to evolve to meet the changing demands. A key point of evolution is its uncertainty since it refers to potential future changes to …
