Now I have become a certified ScrumMaster after a course by Jeff Sutherland. I really like scrum since it makes development fun and is a tool that helps the team communicate. I believe that scrum can make a difference for development teams but at the same time it is not a silver bullet that will write your code. Think of it as a very simple tool for you and your team that makes it fun to work and also will help you increase your development velocity. I am looking forward to work with scrum and would really like to build an expert team that will reach the hyper speed of development and deliver, deliver, deliver :).
