Bug Assignment
Bug tracking is the process of capturing, reporting, and managing data on bugs that occur in software (also called errors and exceptions). The goal is to maintain high product quality, using two types of services: task management systems and bug capturing tools.
Backlog Management
A backlog is a high-level list of everything that the team needs to work on. Backlog Management is therefore the “What” that needs to be accomplished, sorted by importance. The backlog is used in the release and iteration (sprint) planning sessions as the source of features and work to draw from and plan for completion within the time period.
Issue Tracking
It is a method for keeping a record of open problems that, depending on their content, must be solved within the next task, before the next milestone, or before the change effort can be successfully completed.
