From Essential Scrum by Kenneth S. Rubin:
[…]the ScrumMaster observes how the team is using Scrum and does anything possible to help it get to the next level of performance. When problems arise that the team can and should be able to solve, the ScrumMaster’s attitude, like that of any good coach, is “I’m not here to solve your problems for you; instead, I’m here to help you solve your own problems.”
