A bug tracking system is a software application that is

designed to help quality assurance and programmers keep

track of reported software bugs in their work. It may be

regarded as a sort of issue tracking system.

Many bug-tracking systems, such as those used by most open

source software projects, allow users to enter bug reports

directly. Other systems are used only internally in a

company or organization doing software development.

Typically bug tracking systems are integrated with other

software project management applications.

Having a bug tracking system is extremely valuable in

software development, and they are used extensively by

companies developing software products.
