Defect Management is a systematic process used in software development to identify, track, and resolve defects or bugs in a product. It involves various stages, including defect detection, reporting, prioritization, and resolution. The goal is to ensure that the final product meets quality standards and functions as intended. Effective defect management relies on tools and methodologies, such as Agile or Scrum, to facilitate communication among team members. By maintaining a clear record of defects, teams can analyze patterns, improve processes, and enhance overall product quality, ultimately leading to higher customer satisfaction.
