A matrix-based tracing approach and analysis of software requirements changement

Abstract

In software development, the requirements changement is inevitable. First, according to the ripple effect, scenario, use cases, objects and components are related according to their contribution rate together with the matrix. Secondly, according to the value of the size of the matrix determine the impact of cost of the change. Third, according to the interface matrix delineated the extent of change and get the area of change
