Weighted Hybrid Defect Content and Effectiveness Model
Hua Yin Zhang, Jian Long Ding · Advanced materials research · 2013
Requirements analysis phase is an important step which is at the earliest stage of a software lifecycle. If defects are found out at early stage, the cost of a project can be considerably minimized. A weighted method with higher accuracy is developed, based on a Hybrid Defect Content and Effectiveness Model (HDCE) used at requirements analysis phase. In this model, the defects of requirements are classified and every level has different weight value. Moreover, comparison of actual case data clearly indicates that prediction made from this model is more accurate than the prediction made from just using historical data model.
