Comparing scenarios

After you create multiple scenarios of a schedule, you can compare them visually.

About this task

You can compare any two scenarios of the same schedule in the Compare Scenarios window. You can compare the work dates and the labor load for each scenario. Two Gantt charts show when work is scheduled, or you can switch views to compare resource loads. Differences between the two scenarios are highlighted, including work records that are scheduled for different dates, or that appear in only one scenario. You can also compare the current schedule with a baseline, or snapshot, of the original schedule. When you compare a scenario to your baseline, you can see break-in and break-out work. Break-in work is work that was not in the original schedule, but was later added. Break-out work is work that was included in the original schedule, but was later removed.

Procedure

  1. In the Gantt view in the Scheduler application, view a scenario (or snapshot) that you want to compare.
  2. Click Compare Scenarios. The Compare Scenarios window opens, listing all scenarios and snapshots for the schedule. The current scenario is automatically selected. Choose another scenario from the list to compare it to.
  3. Click OK. The scenario window displays the Gantt view of both scenarios, with work dates. Break-ins, break-outs, and differences in work dates are highlighted. You cannot move or modify any dates in the Gantt chart when you compare scenarios.
  4. From the Select Chart menu, choose Load to view the differences in resource loads between scenarios.
  5. Click the Compare Costs tab. Click Calculate Cost to update the costs for both scenarios. Select a tab to display the weekly, monthly, or yearly costs for each scenario.
  6. Click the Compare Costs Chart tab. From the Additional Charts menu, choose the comparison chart that you want to view. For example, click Saved Estimated Total (Weekly) to view the comparison chart for total costs for the week the work is scheduled for.
  7. Click the Gantt View tab. Click the scenario name to return to the Gantt view of the original record.
