Supporting Requirements Model Evolution throughout the System Life-Cycle
Neil Ernst, John Mylopoulos, Yijun Yu, Tien N. Nguyen · 2008
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.
