Running a Simulation vs. Historical comparison
You can compare analysis scenarios in the Optimizer.
Procedure
To run the Simulation vs. Historical (What if) analysis that was automatically generated by the wizard in the preceding sample, follow these steps:
- Go to the Analysis Scenarios view in the Optimizer to see the settings established by the wizard. Notice that the simulation data for the revised process (with the built-in service to bypass the approval step) will be compared to the Historical Analysis Scenario that originally revealed the wait time issue.
- Click Calculate in the Analysis Scenarios view.
Results
The heatmap now shows that the Approval Activity is no longer bottlenecked.
What to do next
You can run similar what-if comparisons by doing one of the following actions:
- Creating different versions of your process with additional services or other workarounds.
- Creating a simulation profile for each version of the process.
- Creating a Simulation Analysis Scenario in which you can pick and choose from the profiles created in the preceding step.
- Running a Simulation vs. Historical (What if) comparison using a default Historical Analysis Scenario (like All Available) for the baseline and the Simulation Analysis Scenario from the preceding step as the sample.
