Cycle Time Control Chart(2.7.12)

Individual delivered-issue cycle times plotted by delivery date, with a rolling mean and upper / lower control limits (mean plus or minus two standard deviations). Points outside the control limits are statistically unusual and worth investigating. Click a point to open the issue in Jira. Use the date and project filters to focus the view.

How this chart works

Scatter plot of individual delivered issues plotted by delivery date (X) and cycle time in days (Y). Issues closed into an abandoned or duplicate status are not plotted and do not move the mean or the control limits. Three reference lines run horizontally per project: the mean (solid gray), the upper control limit μ + 2σ (dashed coral), and the lower control limit μ − 2σ (dashed green). Points are colored by their statistical signal — coral above the UCL (statistically slow outliers), green below the LCL (statistically fast), blue for in-control.

Use the date, project, and issue-type filters to focus. Hover a point for the issue key, cycle days, and signal.
