Improving Defect Removal Efficiency(DRE) for a leading telecom player

Improving Defect Removal Efficiency(DRE) for a leading telecom player

One of the largest enterprise and mobile communication providers across the globe was in need of a sound Defect Removal Efficiency (DRE) solution that would help overcome testing challenges and rectify defects simultaneously. 

Prior to being acquainted with HCL’s iTF, the client was grappling issues while they were going live. With limited time on their hands, it was critical to resolve any kind of repetitive failures/defects. HCL adopted a three pronged approach to meet the client requirements. We started off with a test sufficiency analysis to determine the level of test count and orphan defects. Then, we executed bug segmentation that detected trends in defect pattern, and finally we conducted a code analysis to find out code complexity. Download this case study to know more.
