Metric Framework for Software Reengineering Process to Improve the Efficiency with a Case Study

The reengineering process is used to transform or improve existing software so that it can be understood, controlled and reused as new software. Software metric can help the reengineering process to make the process easy, economical and efficient. Information given by metrics can be used to make a more efficient study of the source code based on the points of interest indicated by the metrics result. In this paper, a metric framework has been proposed for reengineering process to make the reengineering process easy, economical and efficient. In the framework, metrics have been selected that can be used to find the cost of upgradation of software. On the basis of result obtained, a decision can be made regarding maintenance / reengineering / retirement need of the software / part of software. Metric set is also used to find which parts of the software require reengineering. A case study has been undertaken to validate this metric framework.
