Agile Software Development

Scrum Master is specialized in ensuring the scrum process is implemented as intended. He is the one who takes care of the different agile practices to reach the team. Project Manager is the one who takes care of the planning, project deliverables, billing, process, QA, etc...
And now the question for many is can a project survive without the Scrum Master. Its often the case that a traditional project manager takes training as scrum master and he takes the role of a scrum master.
