Purpose

Velocity shows an absolute amount of value (measured in story point or items) delivered within a week or month.

How metric helps

Velocity helps to determine the amount of work a current project team can process within a particular period. Typically this is calculated based on historical iterations e.g. last 3-5 sprints. With this information, a project manager will be able to make an accurate delivery forecast for future iterations. 

How metric works

Chart overview

Chart shows a number of items or story points (Axis Y) delivered in a week/month (Axis X).

On hover over a column, a hint appears with the following information:

  • Week/month dates;

  • Velocity in story points or items.

Chart legend shows the latest values for the metric in story points and items.

Calculation



Iteration Type

Units of Measure

Week 

Month

Item

Number of items (e.g. Stories, Tasks, etc.) which got a 'Done' status within a week

Number of items got a 'Done' status within a month - i.e. between 1st and last day of a month

Story Point

Amount of story points for the items got a 'Done' status within a week

Amount of story points for the items got a 'Done' status within a month - i.e. between 1st and last day of a month



Calculation notes

  1. 'Done' status is Definition-of-Done i.e. any workflow status specified in 'Done' bucket in Project Settings>Data Sources>Task Tracking system>Workflows;

  2. sub-items (i.e. sub-tasks, sub-bugs in JIRA) are not included into the calculation;

  3. only completed week/months are shown in the chart, no future ones;

  4. end of a week is a UTC midnight between Saturday and Sunday (i.e. as per US notation);

  5. end of month is the last day of month at 23:59:59;

  6. If an item is developed during several weeks or months - it is included into the calculation in the week/month it is actually completed.

  7. PERF does not display versions without "start date" and/or "end date", although JIRA allows creating them in this way. Reason for not taking versions without a start/end date in PERF: dates are required for correct calculations and presenting data on the timeline.

  8. Trend line (blue dotted line) calculation (its inclination to axis x) ignores an incomplete iteration in the chart to reveal an accurate tendency.



FYI

Velocity difference between PERF and JIRA

Data Source

Data for the metric can be collected from a task tracking system (Jira, TFS, Rally, etc.).
