摘要：“Discovering the unexpected is more important than confirming the known [7]. In software development,the “unexpected” one relates to defects. These defects when unattended would cause failure to the productand risk to the users. The increasing dependency of society on software and the crucial consequences that afailure can cause requires the need to find out the defects at the origin itself. Based on the lessons learntfrom the earlier set of projects, a defect framework highlighting the 5 Dimensions (Ds) of defect origin isproposed in this work. The defect framework is based on analyzing the defects that had emerged fromvarious stages of software development like Requirements, Design, Coding, Testing and Timeline (defectsdue to lack of time during development). This study is not limited to just identifying the origin of defects atvarious phases of software development but also finds out the reasons for such defects, and defectpreventive (DP) measures are proposed for each type of defect. This work can help practitioners chooseeffective defect avoidance measures.In addition to arriving at defect framework, this work also proposes a defect injection metric based onseverity of the defect rather than just defect count, which gives the number of adjusted defects produced bya project at various phases. The defect injection metric value, once calculated, serves as a yardstick tomake a comparison in the improvements made in the software process development between similar set ofprojects.
