A sign of team self-management success is when the Scrum Master is out or busy and someone just fills in. I’ve known one of our Scrum projects was moving along pretty well, but our organization still has a tendency to try to have another PM fill in at the daily standup. In the old command and control phase this made sense, but with a self-managing team it just becomes a minor impediment. Today I left a Scrum meeting with a big smile as one of the business analysts on the team had facilitated the standup.
Next step is having a rotating facilitator instead of always looking for the Scrum Master to lead.
