Reestruturação de Software Dirigida por Conectividade para Redução de Custo de Manutenção

Most of the software cost is due to maintenance. In the last years, there has been a great deal of interest in developing cost estimation and effort prediction instruments for software maintenance. This work proposes that module connectivity is a key factor to predict maintenance cost and uses this thesis as the basis to develop a Connectivity Evaluation Model in OO Systems (MACSOO), which is a refactoring model based on connectivity whose aim is to minimize maintenance cost. We describe experiments whose results provide an example of the model application and expose the correlation between connectivity and maintainability.
