Ken Schwaber and Jeff Sutherland, the co-founders of Scrum, have been working together and with the Scrum community on updating the official Scrum Body of Knowledge, the Scrum Guide. The core principles of Scrum remain, but misunderstandings have been clarified and techniques have been removed. The “Definitive Guide to Scrum,” focuses on the framework, rules, and ceremonies of Scrum. Emphasis is placed on the roles of the Scrum Team and understanding of their responsibilities, as opposed to the strategies and techniques involved in fulfilling those roles and responsibilities.
The new scrum guide was announced on July 15 but the reasoning behind the changes are not always clear to everyone. To remedy this scrum.org is releasing a series of Scrum Guide Explanations. These explanations are really good, not only do they explain the specific change in question but reading the explanations will also give you a deeper understanding of the core principles of scrum.
