The work titled "Measuring Software Reengineering: A Framework Based on Metric Sets" explores software reengineering, focusing on improving existing systems' performance and maintainability. It proposes a novel approach that employs metrics to guide the reengineering process and enhance software quality. The study recommends practical software measurement practices for evaluating the feasibility of enhancing system maintainability. Three case studies demonstrate the approach's effectiveness, transforming software with issues into more organized, efficient, and maintainable versions. The Rainfall model, incorporating metrics, serves as a structured method for reengineering, addressing different scenarios. The study emphasizes empirical validation, comparing the metric-based approach with traditional methods in real-world projects. Overall, it underscores metrics' potential in managing risks, optimizing reengineering efforts, and providing a systematic approach to software evolution and improvement.
