Level Of Effort Activity Type

Dear Ronald P3e apply the following calculations for the Level Of Effort activities Early start = earliest early start of Level Of Effort Predecessors Late Start = earliest late start of Level Of Effort Predecessors Early Finish= Latest early Finish of Level Of Effort Successors Late Finish= Latest late Finish of Level Of Effort Successors Total Float = Late finish - Early finish Original Duration = Early Finish - Early start Remaining Duration = Early finish - Datat Date % complete = (Original Duration - Remaining Duration)/Original Duration

Dear Ronald

P3e apply the following calculations for the Level Of Effort activities

Early start = earliest early start of Level Of Effort Predecessors

Late Start = earliest late start of Level Of Effort Predecessors


Early Finish= Latest early Finish of Level Of Effort Successors


Late Finish= Latest late Finish of Level Of Effort Successors


Total Float = Late finish - Early finish

Original Duration = Early Finish - Early start

Remaining Duration = Early finish - Datat Date

% complete = (Original Duration - Remaining Duration)/Original Duration

Khalid,

Thank your for your in-depth reply. This does help clear up some things. One warning, though. P3e Level-of-Effort (LOF) activities DO NOT always span the latest start to the earliest finish as published in the manual. They span the dates they are related to.

Unlike P3 Hammocks, LOE activities can have any of the four relationships. An LOE can be related to the start of an activity or its finish. If you use a start-to-start, then LOE will begin when the other activity starts. A start-to-finish will result in the LOE starting when the activity finishes.

The effest of this on the computation of total float (especially when multiple activities are involved) hurts my head thinking about it.

Try to avoid LOE tasks if possible. If you do use them then I recommend that, if you want to measure CPI, SPI and EV, then limit the duration of these activities to 3 months.
Also, the relationship should be SS on the first "hammock" and FF on the last.

P3e 4.0 should clear this matter
