Items in the project backlog are commonly arranged in a hierarchy that reflects the overarching model of the project. This model is usually determined by how the team, and the product, is structured. Complementing this, parts of the backlog can be delegated to users or user groups. This is indicated by the "Delegated to" label next to a subproject label.
Tip: In addition to the default columns, custom columns can be added that cover a large spectrum of agile needs. Please see the customize columns page for more information.
