Scrum was first developed 15+ years ago, and it has been evolving and adapting ever since. Informed by their experiences and those of the Scrum community, Jeff and Ken have carefully codified the framework in the Scrum Guide, which documents the basic rules, artifacts, and events of Scrum.
Today's announcement marks a new era in Scrum's evolution by making available a public mechanism for providing feedback on the Scrum Guide and a model for proposing extensions to the basic framework.
The formal process for proposing and integrating changes into Scrum is available online at Scrum.org. To learn more about Scrum, or proposing your own contribution to Scrum, you can use the following links:

Extend It - http://www.scrum.org/scrum-extensions/
We look forward to hearing from you.
