How does the 'defect lifecycle' manage bugs?

The 'defect lifecycle' refers to the series of stages that a defect undergoes from the moment it is discovered to when it is resolved and closed. This lifecycle typically includes various phases such as identification, reproduction, analysis, resolution, verification, and closure. Each phase provides specific insights and actions that need to be taken to effectively address the bug.

Understanding the defect lifecycle is crucial for managing bugs systematically. It helps in tracking defects, ensuring they are resolved in a timely manner, and confirming that the resolution has successfully eliminated the issue. By defining these stages, teams can systematically monitor progress and improve their quality assurance processes over time.

The other choices, while related to the broader context of software testing and quality management, do not accurately reflect the specific function of the defect lifecycle. For example, outlining generic testing procedures, generating test plans, and providing historical records are important aspects of software development and testing but do not focus on the dynamic process of managing individual defects throughout their lifespan.
