Issue tracking allows organizations to manage changes and bugs in an ordered way. An issue can represent any query, occurrence, or task that may impact a project, such as a software bug, request for change, or action item from a meeting. When an issue is reported, it goes through a typical workflow of being assigned, accepted, worked on, and eventually closed or reopened. Popular open source bug trackers include Bugzilla, Trac, and JIRA, with Trac being a good example of a lightweight yet powerful option that allows cross-referencing with wikis and version control systems.
