Developing Fault- Prediction Models: What the Research Can Show Industry

CODE FAULTS ARE a daily reality for software development companies. Finding and removing them costs the industry billions of dollars each year. The lure of potential cost savings and quality improvements has moti-vated considerable research on fault-prediction models, which try to iden-tify areas of code where faults are most likely to lurk. Developers can then focus their testing efforts on these areas. Effectively focused test-ing should reduce the overall cost of finding faults, eliminate them earlier, and improve the delivered system’
