The technique relates to a system and method for estimating an impact of changing one or more source files in a software based on a clone dependency graph. This technique involves extracting the source files from a repository and detecting code cones present in the source files. After detecting the code clones the clone dependency graph is created. Several graph metrics are calculated and applied to the clone dependency graph to estimate the impact of changing a source file on other source files of the software. Finally, the output is visualized with the help of graph visualization technique.
