In order to prevent more defects from escaping to end-users for a V-model development process, independent testing team needs a predicted total number of defects for any software under test at the start of system testing so that defects can be fixed as early as possible. Metrics from requirement to coding phases are required to develop this defect prediction. Thus, this research introduces and explains the systematic approach to predict system testing defects for a V-model by using prior phases metrics. By applying regression analysis as part of the approach, it demonstrates that total number of defects in system testing can be predicted by using requirement, design and coding metrics. The approach produces a mathematical equation which is used to predict defects in system testing. The equation is then verified on new software projects so that it is fit for final implementation and integration into software development process.
