Scrum is a framework for project management that focuses on iterative development, self-organizing teams, and frequent inspection points. It originated from rugby where players pack closely together with heads down to gain possession of the ball. In Scrum, a product owner prioritizes a backlog of work for self-organizing development teams to complete in iterations called sprints. Daily stand-up meetings provide transparency and help teams course correct. Scrum values include focus, courage, openness, commitment, and respect.
