In last few days I have compiled some information on SCRUM in separate articles. Here is the consolidation of all the links:
Scrum has been successfully used for projects with 500+ team members lots of time. As SCRUM can only last for 15 minutes and some other similar rules hence in order to scale the SCRUM for bigger team we can use SCRUM OF SCRUMS. Based on the type of work the scrum team is constituted for every 7 to 10 team members having a Scrum master and the Product Owner. After the first lever team SCRUMS we have SCRUM of SCRUMS and there could also be more level of SCRUM OF SCRUMS.
I have listed all these and also linked them to wiki as it has one of the very good definitions and details about every agile methodology.
Once I am done with the Scrum series I will touch the other ones. Hope this helps!

Everyone answers 3 questions and the Scrum Master documents this:
