Build Scenario Command on the S3 // Risk Tab

Click this command to build a new scenario based on the current risk model or use the options in the drop-down menu to specify the scenario settings.

Copy

Field Description
Create Copy Select this command to copy the current risk analysis model to evaluate alternate scenarios. A new scenario called <current model name> scenario is added to the Projects pane.

Risk Inputs

Creating scenarios based on risk inputs is useful when needing to re-calibrate a schedule based on the project's team uncertainty rankings.

Field Description
Scenario based on Risk Inputs Use these commands to specify whether you want a scenario built using a weighted average or an average value. You can achieve this using one of the following modes:
  • PERT Method uses the PERT algorithm ((max+4*most likely+min)/6 to re-calibrate the schedule/cost model.
  • Distribution Median takes the median value between min, most likely, and max to re-calibrate the schedule/cost model.

Risk Outputs

Field Description
Scenario base on Risk Outputs Select a number in the P Schedule field to create a scenario based on any P-Value from the risk analysis. After creating the scenario, you can publish the risk-adjusted schedule back to the scheduling tool or use it as the basis for building a new risk model.
Note: When you select Scenario based on Risk Outputs while Run CPM Automatically is on, a warning prompt displays to confirm if you want to run CPM. Running CPM on a risk scenario may change the dates.
Field Description
Run CPM Automatically When you select this option, Acumen runs the Critical Path Method automatically. Use the fields on the S3 // Risk Activity Pane Settings tab to specify how you want Acumen to perform the CPM.

For example: You have two activities, Activity A and Activity B. There is a finish-to-start link between them which means that Activity B can't start before Activity A is finished. For some reason, Activity B has started before Activity A has finished, that is, Activity B is now out of sequence.

  • If you select a Retain Logic scheduling mode, Activity B cannot finish until Activity A is finished. The system schedules the remaining duration of Activity B to begin after Activity A is finished. That is, Activity B is put on hold until Activity A is finished.
  • If you select a Progress Override scheduling mode, the system ignores the start-to-finish link between Activity A and Activity B and the activities finish in no particular order.
  • If you select an Actual Dates scheduling mode, the system sets the late finish date of Activity A to one day before the actual start of Activity B which creates negative float.
