1. A processor-executed method for providing a predictive model of an automated fix release process, the method comprising: tagging a defect indicating attributes of the defect and a feature associated with the defect, wherein the feature is included in a fix for the defect; assigning a value to each of the attributes; establishing a mapping of the defect and the feature based on the tagging; storing codes implementing the fix in directories, wherein the code directories are structured to indicate features of the fix; adding to the mapping an association of the features and the fix derived from the code directories; adding an association of a test case with the features to the mapping; and calculating a vulnerability of the fix, the features, and the codes using the value assigned to each of the attributes of the defect and the mapping; decomposing each of the features to sub-features; adding an association of the features and the sub-features to the mapping; calculating an individual value for each of the sub-features as a function of the values assigned to attributes of defects associated with the sub-features derived from the mapping; and calculating an overall value for the each of the features as a function of the individual value for each of the sub-features.
