A defect life cycle is an important part of Quality Assurance (QA) in software engineering. It is a process used to detect, isolate, and document defects in software applications. Through this cycle, testers identify, validate, and manage their defects with the goal of delivering bug-free software applications. The life cycle generally follows four steps: initiation, analysis, fixing and closure. The goal of the process is to identify and eliminate software defects in order to enhance the user experience.
