Scrum Master roles: Some scrum coaches rank among the nicest and most thoughtful people that I ever met. However, the general concept is very suspicious. A scrum master is not supposed to lead the team, code, or take responsibility for deliverables. What do they do? Massage? Get a real job. We use tech leads, who can understand the code that flies around a distributed team, and take responsibility for deliverables. I shed more light on this back in Novemeber with a popular post – Tech Leads will Rule the World.
