Defect Lifecycle

The defect lifecycle, also known as the bug lifecycle, is a structured process that tracks the progression of a defect from when it is reported to its resolution and closure, ensuring that no defects are overlooked and all stakeholders remain informed about the defect status. This lifecycle consists of multiple stages, including identification, assignment, analysis, resolution, retesting, and closure, with roles such as QA engineers, developers, test leads, test managers, and project managers playing crucial parts in managing and resolving defects. Severity and priority are critical attributes in defect management, guiding teams on where to focus their resources based on the defect's impact and urgency. Effective defect lifecycle management relies on key metrics like defect density, defect leakage, resolution time, and closure rate to identify process bottlenecks and improve software quality. Adopting best practices, such as defining clear workflows, utilizing metrics, promoting collaboration, and training teams, can streamline the defect management process and align it with organizational goals, ultimately enhancing customer satisfaction.
