A Sprint is a container of a set of Items for delivery that have been agreed to during Sprint planning by the Team and the PO.
It typically has three states for an Item: “To do”, “In Progress” and “Done”. Sprints are executed one after the other (1-4 weeks length).
Items or cards exist in lanes within a Sprint lane. Each of these lanes can be reordered by dragging the grab menu at the beginning of the lane in the To Do column.
Tasks can be created directly in the lane a Story is in, using the 
icon.
