Analytics
=========

Each project have an analytics section. Depending on how you are using Kanboard, you can see those reports:

User repartition
----------------

![User repartition](screenshots/user-repartition.png)

This pie chart show the number of open tasks assigned per user.

Task distribution
-----------------

![Task distribution](screenshots/task-distribution.png)

This pie chart gives an overview of the number of open tasks per column.

Cumulative flow diagram
-----------------------

![Cumulative flow diagram](screenshots/cfd.png)

- This chart shows the number of tasks cumulatively for each column over the time.
- Every day, the total number of tasks is recorded for each column.
- If you would like to exclude closed tasks, change the [global project settings](project-configuration.markdown).

Note: You need to have at least two days of data to see the graph.

Burn down chart
---------------

![Burndown chart](screenshots/burndown-chart.png)

The [burn down chart](http://en.wikipedia.org/wiki/Burn_down_chart) is available for each project.

- This chart is a graphical representation of work left to do versus time.
- Kanboard use the complexity or story point to generate this diagram.
- Everyday, the sum of the story points for each column is calculated.

Average time spent into each column
-----------------------------------

![Average time spent into each column](screenshots/average-time-spent-into-each-column.png)

This chart shows the average time spent into each column for the last 1000 tasks.

- Kanboard uses the task transitions to calculate the data.
- The time spent is calculated until the task is closed.

Average Lead and Cycle time
---------------------------

![Average time spent into each column](screenshots/average-lead-cycle-time.png)

This chart show the average lead and cycle time for the last 1000 tasks over time.

- The lead time is the time between the task creation and the date of completion.
- The cycle time is time between the specified start date of the task to the completion date.
- If the task is not closed, the current time is used instead of the date of completion.

Those metrics are calculated and recorded every day for the whole project.

Note: Don't forget to run the [daily cronjob](cronjob.markdown) to have accurate statistics.
