Estimation & Velocity

User stories are estimated using story points

Story points are relative, as relative estimations are easier for humans

Story points are estimated in a relative size and compared to relative sizes of other user stories

The estimation takes into account

• The amount of work

• Uncertainity

• Dependency

• Complexity

Velocity is the amount of work a team finished in one sprint

It provides an index on how much the team should add or remove in the next sprint

Only fully completed user stories are added to the velocity calculation

Velocity is also used as an input to retrospectives

Velocity of a team is unique and can not be compared to other teams

Sprint Burndown Charts are graphical representations of the remaining work in a sprint

Burndown Charts can be tracked in:

• Story Points (Stories)

• Time (Tasks)

• Issue Count (Stories & Tasks)

Release Burnup Charts are used to track the progress of the team within a realease

They are measured in Story Points or amount of Stories completed

Partially completed stories are not added to the chart

Burnup Charts are used for accommodate chanigng scope
