Some Good Scrum References

There is a ton of stuff out there on Scrum. About 6,350,000 hits on Google! Our small core team has been scouring this stuff; here are few of the best we've found:

1. http://www.crisp.se/henrik.kniberg/ScrumAndXpFromTheTrenches.html
   

   This is an excellent article which chronicles some real-life Scrum experiences, highly recommended reading.
   

2. http://scrumforteamsystem.com/ProcessGuidance/Scrum/Scrum.html
   

   Nice pictorial overview.
   

3. http://www.scrumalliance.org/
   
4. http://www.mountaingoatsoftware.com/
   

   The last two are just good general sites, containing lots of articles.
