About the Control Chart
-
The Control Chart shows the Cycle Time (or Lead Time) for your product, version, or sprint. It takes the time spent by each issue in a particular status (or statuses), and maps it over a specified period of time. The average, rolling average, and standard deviation for this data are shown.
-
A Control Chart helps you identify whether data from the current sprint can be used to determine future performance. The less variance in the cycle time of an issue, the higher the confidence in using the mean (or median) as an indication of future performance.
-
Here are some of the ways that you could use a Control Chart:
- Analyze your team’s past performance in a retrospective,
- Measure the effect of a process change on your team’s productivity,
- Provide external stakeholders with visibility of your team’s performance, and
