Supporting requirements model evolution throughout the system life-cycle

Ernst, Neil; Mylopoulos, John; Yu, Yijun and Ngyuen, Tien T. (2008). Supporting requirements model evolution throughout the system life-cycle. In: 16th IEEE International Requirements Engineering Conference, 08-12 Sep 2008, Barcelona, Spain.




Requirements models are essential not just during system implementation, but also to manage system changes post-implementation. Such models should be supported by a requirements model management framework that allows users to create, manage and evolve models of domains, requirements, code and other design-time artifacts along with traceability links between their elements. We propose a comprehensive framework which delineates the operations and elements necessary, and then describe a tool implementation which supports versioning goal models.
