This document outlines the Scrum Guide, which defines Scrum and its roles, events, artifacts, and rules. Scrum is an agile framework for managing complex work. Key aspects of Scrum include short "Sprints" of work, daily stand-up meetings, sprint planning and review sessions, and artifacts like the Product and Sprint Backlogs to track work. Scrum values self-organizing, cross-functional teams and transparency through its defined process of iteration and inspection.
