For those not familiar with agile development and Scrum, a ScrumMaster may sound like a new term for project manager.
Those familiar with Scrum, however, know that the truth is very different. In many ways, a ScrumMaster is the antithesis of an old-school project manager. Instead of telling, the ScrumMaster coaches. Instead of directing, the ScrumMaster guides. Instead of being the authority, the ScrumMaster serves.
