A Scrum Master Is Not A Project Manager By Another Name / quote 1 of 5
The ScrumMaster supports the product owner
The ScrumMaster is there to help, coach, provide a consultancy role, and look at the project from all angles. The project remains the responsibility of the product owner, and it's up to him or her to make the final decisions. However, the product owner can look to the ScrumMaster to help answer questions about user experience, functionality issues, user feedback, and any need to realign the development to fit with changes outside the business. The ScrumMaster helps the product owner understand how to effectively manage the work of the team, using the product backlog and the planning and review meetings.
