The initial model for change impact analysis of requirements focuses on identification of requirement level dependencies, which helps in predicting the scope (intensity and depth) of change impact. The change impact analysis model is a multidimensional concern-slicing approach that facilitates understanding of requirements dependencies and impact of requirements change. The concerns are sliced as temporal, conditional, task-oriented, and business rules. Based on stakeholders’ preferences and system requirements the four concern slices are assigned to particular weight bands. Dependency graphs for each concern slice are constructed from semi-formal dependency equations, which assist in analyzing the consequential change impact.
