This report provides some excellent information about the state of Scrum based on a survey of over 500 professionals. I hope that the scope of this survey grows to include many more people over time so that the results are more reliable.
Here is one interesting quote from the report:
Insight #3: The long-term success of Scrum is about creating a culture and making Scrum principles and practices the “new normal.”
Lots of interesting data in the report that backs that up!
The link to the report as well as a webinar and presentation deck are available on the Scrum Alliance site.
