The Defect Lifecycle, also known as the bug life cycle, is the sequence of stages a defect goes through from its initial discovery to its closure. This lifecycle begins when a defect is first identified and reported, and it proceeds through various phases including verification, analysis, assignment to a developer, correction of the defect, retesting by the QA team, and finally, closure of the defect if it is resolved satisfactorily. If the problem persists, the defect can be reopened and the cycle starts again. The lifecycle provides a structured framework for managing and tracking the progress of defects, ensuring they are addressed efficiently and effectively.

Defect tools, also known as bug tracking or issue tracking tools, are software applications designed to help teams manage and track defects, bugs, or issues in their software development projects. These tools enable the recording, reporting, and monitoring of defects throughout the development lifecycle, facilitating a systematic approach to identifying, categorizing, prioritizing, assigning, and resolving software bugs. By providing a centralized platform for tracking the status of identified issues, defect tools enhance collaboration among team members, improve efficiency in the debugging process, and contribute to the overall quality of the software product. They are integral to maintaining project timelines, ensuring product reliability, and optimizing development workflows.

In Agile development, managing defects efficiently is crucial for maintaining high-quality software.
