What is a system used for recording and managing software defects to improve team efficiency?

The system referred to for recording and managing software defects that directly contribute to enhancing team efficiency is best described as bug tracking. This method involves documenting issues and bugs found during the software development process, allowing teams to manage these defects systematically.

Bug tracking systems facilitate clear communication among team members about the status of different issues. They help prioritize bugs based on severity, track the progress of fixes, and ensure that no issues are overlooked. By providing a structured environment to report, assign, and resolve software defects, bug tracking contributes significantly to improving productivity and maintaining software quality over time.

While bug reporting refers to the act of reporting individual defects and might be part of the bug tracking process, it does not encompass the management aspect essential for team efficiency. An issue tracker could be considered overlapping with bug tracking but is broader in scope, as it may not focus solely on software defects. Quality control, on the other hand, pertains to broader quality assurance practices and does not specifically address the management of software defects. Thus, bug tracking stands out as the most accurate answer in the context of the question regarding a system specifically designed for this purpose.
