Fault Proneness of Classes in Object-oriented Systems

Predicting fault proneness of classes in object oriented systems (OOS) is one of the fault management activities and may be considered as one of the cost effective ways to deal with faults. Prediction of faults needs identification and measurement of various factors that affects fault proneness of classes in OOS. In this paper, several design oriented factors have been identified that help in codetermining the fault proneness of a class in object oriented systems. Fault proneness is finally aimed at indicating the risk levels associated with the classes so as to focus on these classes in design of object-oriented systems accordingly. Further, existing relevant object-oriented metrics have also been suggested for measuring the fault proneness.
