Backlog (agile)

A backlog is a queue that contains all of the potential work items that could be built, including actual work, proposed features, good ideas, or discovered defects. The items in a backlog should cover the entire product's lifecycle, from the current release (and the current sprint) to future releases (and future sprints). All items in a backlog can be viewed as an ordered list (sorted by rank), in a table, or by in a tree (grouped as parent/child work items, as defined by your organization's work breakdown structure).
