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.
