Defining Assignment Profiles Manually

Although it is possible to define a simple profile for each assignment using one of the standard curves, the use of assignment offsets and periods, combined with the ability to specify more than one assignment for the same resource, allows you to define much more complex resource profiles for an activity.

Using offsets and periods, for example, you can construct the following profile by defining 3 resource assignments for an activity with duration of 5 days:

Resource Curve Level Offset Period
TUBING (blank) 50 0 (or blank) 5d (or blank)
TUBING (blank) 25 2d 3d
TUBING (blank) 100 3d 1d

This results in the following resource profile:

A potential disadvantage of this approach, however, is that subsequent changes in the planned duration of an activity may have unintended consequences for the definition of offsets and periods.

In cases where activity progress has been recorded and an activity is partially complete, Open Plan takes the offset duration relative to the original activity duration when calculating resource usage but bases this calculation on the end of an activity duration rather than its beginning.

Note: For more information about the effect of progress information on resource scheduling, see "The Effect of Progress Information" in the Deltek Open Plan Developer’s Guide.
