The Cycle time breakdown summary graph displays the percentage of the total time invested for each step of your process and the average time spent.
Depending on the display mode selected, it calculates the average time to go from one step to another (e.g. from QA to deployment) and calculates the percentage based on the specified cycle time.
The data displayed on the right side of the graph represents the three stages of the workflow with the most significant portion of time invested for the given period. This graph is interactive, so you can hover over it with your mouse to get more information about the other stages of the cycle.
