Making metrics visual
One of kanban's core values is continuous improvement. But how do teams ensure they're continuing to improve? One word: visuals. When the team can see data, it's easier to spot bottlenecks in the process (and remove them!). Two common reports kanban teams use are control charts and cumulative flow diagrams.
A control chart shows the cycle time for each issue as well as a rolling average for the team.
ProTip: The team's goal is to reduce the amount of time an issue takes to move through the entire process. Seeing the average cycle time drop in the control chart is an indicator of success.
