Fuzzy Logic Based Revised Defect Rating for Software Lifecycle Performance Prediction Using GMR

Software service organizations have adopted various software engineering process models and are practicing it earnestly. Even though this has helped the organizations to improve the quality and the profit margins; there exists a need to compare different groups within it so as to concentrate on the weaker sections. In this paper, the authors propose a revised model for defect rating that can be used for calculating group maturity within the organization. Fuzzy logic approach is used for the proposed model considering the linguistic or imprecise nature of the software measurements. The output of this model can be used as one of the parameter for predicting different software parameters within the software lifecycle. . Index Terms - Defect rating, Fuzzy logic, Historical data.
