Cycle Time Control Chart

Individual issue cycle times plotted by completion 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 completed issues plotted by completion date (X) and cycle time in days (Y). 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.
