Great job on starting a new lesson! After reading this lesson, click Next button at bottom right to continue to the next lesson.

Defect Management is the process of creating, categorizing, analyzing, resolving and tracking defect reports. It helps to organize, and manage the defect reports and get reports on the current status of defect reports.

Defect Management Example

• The tester finds that the login button on their website does not work. He reports the defect with a unique auto-generated ID, summary, description, steps to reproduce, test data used, severity, priority, and screenshots.
• The developer analyzes and fixes the defect, and marks it as resolved. She also provides the version of the software where the defect was fixed.
• The tester verifies that the defect is fixed by retesting the login button on the their website. He marks the defect as closed if it is fixed or reopens it if it is not.
• The test manager analyzes the defect data and generates reports on defect trends, root causes, and quality metrics.

Tips for Defect Management

• Use the standard defect tracking tool to record and track defects throughout the software development lifecycle.
• Use the standard defect report template to provide clear and consistent information about defects.
• Prioritize defects based on their impact and urgency. Fix and re-test high-severity and high-priority defects first.
• Communicate effectively with the developers to resolve defects quickly and efficiently.
• Review the defect reports to learn how to prevent them from recurring in the future.
