Virhehallintajärjestelmä

Virhehallintajärjestelmä, often translated as a defect tracking system or bug tracking system, is a software application used to manage and track defects or bugs that are found in software development projects. Its primary purpose is to provide a centralized repository for reporting, prioritizing, assigning, and resolving issues identified during the testing phase or reported by users.

These systems typically allow users to log new defects with detailed information, including steps to reproduce the issue, expected versus actual results, severity of the problem, and any relevant attachments like screenshots or log files. Once a defect is logged, it can be assigned to a specific developer or team for investigation and resolution. The system then tracks the status of the defect through its lifecycle, which might include states like open, in progress, resolved, or closed.

Virhehallintajärjestelmät play a crucial role in improving software quality by ensuring that all identified issues are systematically addressed. They facilitate communication between testers, developers, and project managers, providing transparency into the defect resolution process. By maintaining a historical record of defects, these systems can also help identify trends, recurring problems, and areas where the development process might need improvement. Popular examples of such systems include Jira, Bugzilla, and MantisBT.
