What is standard deviation in agile?

Well, they denote one standard deviation from the Mean. ‘One standard deviation’, aka one sigma, shows the boundaries between which the majority (68%) of your data sits – by referencing a margin either side of your Mean. Our example has a mean of 15, with one standard deviation of 2.67.

What is the control chart in JIRA?

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:

How to calculate the rolling average in Jira?

For example, in the screenshot below, at the point of time where an issue (green dot) is shown, the rolling average is calculated as follows: Take the issue plus four issues before and four issues after (nine issues total). Average the cycle times for the nine issues. Map the blue line to the calculated average.
