TL; DR: The Scrum Guide Reordered
The Scrum Guide Reordered 2020 is based on about 95 percent of the text of the Scrum Guide 2020, extending its original structure by adding additional categories, for example, on self-management, commitments, or accountability.
The Scrum Guide–Reordered allows you to get an understanding of Scrum-related questions quickly. For example, it is good at relating a specific topis — say “stakeholder” — with Scrum’s first principles such as Scrum Values, or empiricism.
