| In this research, we present a lightweight approach to identify the impact of requirement changes at the specification level. We use specification information included in Use Case Maps to analyze the potential impact of requirement changes on a system. We propose dependency definitions and algorithms to identify Use Case Map scenario and component relationships. Also, techniques for ripple effect analysis at the scenario, component and element levels of abstraction are presented. Further, we present our tool that implements the proposed approaches showing the possibility of automation. A simple case study makes use of this tool to analyze an existing Use Case Map to show the information that is returned by our approach and its applicability in change impact analysis.
