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.

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.

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
