In engineering, defect tracking is the process of finding defects in a product, (by inspection, testing, or recording feedback from customers), and making new versions of the product that fix the defects.
Defect tracking is important in software engineering as complex software systems typically have tens or hundreds of thousands of defects: managing, evaluating and prioritizing these defects is a difficult task. Defect tracking systems are computer database systems that store defects and help people to manage them.
