Sprint
The heart of Scrum is the sprint,
a time period[Time Box] of maximum
one month, within which a
finished["Done"], a usable and
potentially deliverable product
increment is produced.All sprints within a development
project should have the same
duration. The new sprint starts
immediately after finishing the
previous sprint.Asprintincludessprintplanning,daily
