Scrum, as originally outlined in the Scrum Guide, is a framework for developing, delivering, and sustaining complex products by a single team. Since its inception, its usage has extended to the creation of products, processes, services, and systems that require the efforts of multiple teams. Scrum@Scale was created to efficiently coordinate this new ecosystem of teams. It achieves this goal through setting up a “minimum viable bureaucracy” via a “scale-free” architecture.
