Scrum is the most widely adopted framework for implementing 📝Agile software development, co-developed by Ken Schwaber and Jeff Sutherland in the early 1990s and first formally presented at the OOPSLA conference in 1995.

Scrum is built on empiricism — the idea that knowledge comes from experience and decisions should be made based on what is observed — and organizes work into fixed-length iterations called Sprints, the container event around which all other Scrum events (planning, daily coordination, review, and retrospective) are structured. Rather than fixed roles, current versions of the framework define three sets of accountabilities that replaced the earlier Product Owner, Scrum Master, and Development Team role labels, reflecting the framework's continued evolution since its original definition three decades ago.
