 Scrum is one of the methodologies under the Agile umbrella. The name is derived from a method of resuming play in the sport of rugby, in which the entire team moves together to make ground. Similarly, a scrum in Agile involves all parts of the team working on the same set of goals. In the scrum method, a prioritized list of tasks is presented to the team, and over the course of a "sprint" (usually two weeks), those tasks are completed, in order, by the team. This ensures that the highest-priority tasks or deliverables are completed before time or funds run out.
