The Delay Amount section of the Schedule Health page displays the planned duration of the project (solid blue color) as well as the predicted duration which can represent either a delay or early finish (striated red color). The predicted duration is calculated with a 10% probability and an 80% probability.
In the above example, the Haitang Corporate Park project has a Planned Duration of 521 days. The Predicted Duration with a 20% probability of delay is 526 days that includes a delay of 5 days whereas the Predicted Duration with an 80% probability of delay of 718 days, with a predicted delay of 197 days.
Note: If there is no delay (zero), then the planned duration is identical to the predicted duration of the project.
