InfoQ: have a interesting discussion about the value of the
Certified Scrum Master certification.
I've always been trouble by the value of CSM certification, not because of the course per say, but the fact everyone who turns up for the course is awarded it, and the the certification is being used by people to suggest that are experienced at running Scrum projects.
However the big players in Scrum are starting to take notice and are discussing the need for a test at the end which would ensure that every candidate has the required level of understanding of Scrum before they can use the CSM certification
