Duration Uncertainty Tab of the Activity Details Pane

This tab includes information about remaining duration, duration uncertainty, and risk notes.

Note: If you are working with cost uncertainty, then this tab is disabled.
Field Description
Remaining This field displays the remaining duration for the selected activity.
Probability of Existence If you are not 100% certain that a task is going to happen in your schedule, you can assign a probability to the task to reflect this confidence level. You can either enter a percentage in this field or in the % column on the S3 // Risk Activity grid.
Enable Duration Uncertainty Select this check box to enable duration uncertainty for the selected activity. When you select the check box, the following additional fields display:
  • Distribution Type
  • Minimum Remaining Duration
  • Most Likely Remaining Duration
  • Maximum Remaining Duration

Acumen includes three distribution types when modeling uncertainty: Triangle, Normal, and Uniform. The uncertainty values are displayed using both an absolute and a percentage value. If you change the one value, Acumen automatically recalculates the other. For example, if you change the percentage value, Acumen will automatically recalculate the absolute value as soon as you move off the field, and vice versa.

Use the fields to edit the percentage or duration for the selected activity.

Risk Notes Use this text box to enter any additional notes about the activity risks. These notes are only available for reference on this tab and the Cost Uncertainty tab.
