Average Velocity
Purpose
Average Velocity shows an amount of value (in story points or items) delivered within 1 - 3 - 6 - 12 months/sprints or 4 - 13 - 26 - 52 weeks.
How metric helps
Average Velocity helps to compare the productivity of a team on a long-term versus a short-term time interval - it reveals if an overall performance improves or degrades.Â
Questions it answers:
how much work the team can take on/commit to
how much effort your team can handle in next Sprints
how many items from the product backlog to select for a sprintÂ
how total work is consistent with past sprints
what is overall project velocity
what is tendency of teams velocity (improvement or degradation)
what numbers of SP/items could be used for planning proposes
what is the rate at which User Stories are being completed by the team
How metric works
Chart overview
Chart shows a number of items/story points - Axis Y delivered in time - Axis X (1 - 3 - 6 - 12 months/sprints or 4 - 13 - 26 - 52 weeks).
On hover over a column, a hint appears with the following information:
Period of the calculation;
Average Velocity in story points or items;
Median velocity in story points or items.
Chart legend shows the latest values for the metric in story points and items.

Calculation
Velocity calculation | Time period | ||
Units of Measure | Week | Month | Sprint |
---|---|---|---|
Item | Number of items got a 'Done' status before the week end within 4/13/26/52 weeks divided by a number of weeks | Number of items got a 'Done' status before a month end within 1/3/6/12 months divided by a number of months | Number of items got a 'Done' status before a sprint end within 1/3/6/12 sprints divided by a number of sprints |
Story Point | Amount of story points for the items got a 'Done' status before the week end within 4/13/26/52 weeks divided by a number of weeks | Amount of story points for the items got a 'Done' status before a month end within 1/3/6/12 months divided by a number of months | Amount of story points for the items got a 'Done' status before a sprint end within 1/3/6/12 sprints divided by a number of sprints |
Calculation notes
'Done' status is a status placed in 'Done' bucket in Project Configuration>Data Sources>Task Tracking System>Workflows;
a calculation depth value is a value for the setting in Project Configuration>Data Sources>Task Tracking System>Scope Management>Calculation depth for average team velocity estimation;
sub items are included into the calculation if "Include sub items into metrics calculation" setting is on.
only completed week/months/sprints are shown in the chart;
items/story points delivered in already completed weeks/months/sprints are included into the calculation;
story point value at the moment of the assignment to a sprint is taken into the calculation;
week/month /sprint end is the last day of a week/month/sprint at 23:59:59;
end of a week/month is Saturday according to USA calendar.
Data Source
Data for the metric can be collected from a task tracking system (Jira, TFS, Rally, etc.).
