A story is a brief statement of a product requirement or a business case. A story should
be small enough to be completed in one sprint.
The estimated effort required to complete a story is measured in story points, with more points
being assigned to stories requiring more effort. Story points are arbitrary measurements of the
effort (not necessarily the time) required to complete a story, based on the estimates of group
members. The work required for a story can be broken down into discreet scrum tasks.
After creating stories and tasks, manage and track them
to completion through the story and scrum task progress boards.
