This portion of the Baseline Comparison provides summary performance measures, much
like the Performance Metrics window. The number of Late, Early, On Time, and
Incomplete orders are absolute measures. Note that the values for both the Baseline and

Average Late and Average Early provide the average time a late order is late and the
average time an early order is early. There are six additional panels in the lower portion of
this window, which are currently blank. This area will be used to show the detailed
differences between two schedules once we are doing comparisons.

update the statistics in this window. Now select the Sequence > Unallocate All Orders
menu option to clear the planning board. Note the changes in the Baseline Comparison
window. Now let’s try the Sequence > Forward > By Due Date menu option.
The statistics in the Baseline Comparison window now show the data for the schedule
generated using due date, as well as additional statistics comparing this schedule to the
base case schedule. The upper portion of the Baseline Comparison window is shown
below.
The data in the left column are the statistics for the base schedule (in this case, the
schedule generated using the sequence forward by release date method). The data in the
second column are for the new schedule (the schedule generated using the sequence
forward by due date method). The data in the far right column show the absolute
difference between the current schedule statistics and the base case schedule. The data in
