Hello

 

The following example shows the distribution of resources in time, through the Timephased included in the Task Usage View and in the Resource Usage View. Probably the only views that allow to show the result of the units recalculation, when the duration of a Fixed Work Type task is changed.

 

 

The example shows first the case of a Task 1, with a Duration of 10 days, a Work of 80 hours, and a single Resource A (1 Unit).

 

The following image shows the result of the manual reduction of the Durations of the tasks in half (5 days), so that by keeping the work constant (80 hours), Ms Project doubles the number of resources assigned to the task (2 Units), according to the formula:

 

Work = Duration x Resource Units

 

Note.- To show the Units field (Peak Units), in the timephased: Click with the right mouse button on the timephased, select Detail Styles..., and move Peak Units field from the list on the left to the right area of Show these fields, and OK.

 

Regards
