This study demonstrates an objective method used to evaluate the ‘enhanceability’ of commercial software. It examines the relationship between enhancement and repair, and suggests that enhancement be considered when developing formal models of defect cause. Another definition of ‘defect-prone software’ is presented that concentrates attention on software that requires unusually high repair considering the magnitude of planned enhancement.
