My understanding. Please correct if wrong.
The delivery ownership of end solution lies with development team and not scrum master. In traditional method, the project manager is responsible for tracking of product and share the plan to the management. The PM prepares daily plan and has control on the project.
In agile, there is no such concept. There is no commitment to deliver on certain date from development team. Only rough estimation is done and if it is not completed in a sprint, the user stories can be moved to next sprint. Even though we can track the hours spent on daily basis, We can't surely say when the project will be completed?
Every one does their job and update the tasks. If it succeeds, all will get the credit. If it fails, every one sees others faces.
Others view on this please. Thanks
