Bugzilla is a robust, featureful and mature defect-tracking system, or bug-tracking system. Defect-tracking systems allow teams of developers to keep track of outstanding bugs, problems, issues, enhancement and other change requests in their products effectively. Simple defect-tracking capabilities are often built into integrated source code management environments such as Github or other web-based or locally-installed equivalents. We find organizations turning to Bugzilla when they outgrow the capabilities of those systems - for example, because they want workflow management, or bug visibility control (security), or custom fields.
