In business Bug Tracking is the system used by developers
to record defects and changes in software products. Bug-tracking
solutions are designed so that any member of the development team
can access the bug database to log bugs and make changes.
A record of all changes is kept, including time of original bug
identification, bug description, changes / fixes applied, as well
as the developer who made the entry or change. Bugs can be
categorized based on criteria such as urgency or location, and hence
can be quickly sorted according to query.
