I am now a Certified ScrumMaster.
I returned from the two day course in Sydney tonight. I wholly recommend that if you're interested in Scrum that you attend a course like this.
What did I learn? Lots - and it's great to interact whilst learning. I had read the book and have been trying to get something like Scrum implemented for a while now. But to be able to talk with those that have is refreshing.
(And no, I didn't receive any gifts or payments for this recommendation. In fact, I had to fund the entire cost myself, including losing 2 days pay!)
