Which outcome is expected as Scrum Teams mature?
A. They will improve their definition of "Done" to include more stringent criteria.
B. The Sprint Retrospectives will grow to be longer than 4 hours.
C. There is no need for a time-boxed Sprint, since time-boxes are only for new Scrum Teams.
D. Sprint Reviews will no longer be needed.
E. A Scrum Master is no longer needed since they are a mature team now.
