The present invention describes a method and a computer program product for finding an impact of a change on a computer generated code. The method includes the generation of a dependency graph for the computer generated code. The dependency graph includes a plurality of nodes that are connected logically by one or more edges. The method enables an expert to assign nodal weights to the nodes, based on their importance. The method also enables the expert to assign edge weights and distribution ratios, based on the criticality of the relationship between the nodes and their distance from the root node. Thereafter, the impact of the change is found by implementing a spreading activation technique on the dependency graph. The output gathered after the activation represents the impact of the change on the computer generated code.
