Products > PSOP > Documentation Why do my Level of Effort activities have a longer duration than necessary? If the project contains a WBS summary activity that summarizes an Level of Effort (LOE) activity then the LOE activity will incorrectly have the same start and end dates as the WBS activity. For example, suppose you had three activities A1, A2, and A3 which are scheduled at the following times: Activity Start Time End Time A1 0 10 A2 5 15 A3 10 20 Furthermore, assume all three activity have WBS code W.1. We then add an LOE activity with WBS code W.1 which has A1 as a predecessor and A2 as a successor. The LOE activity should thus start at time 0 (when A1 starts) and finish at time 15 (when A2 finishes). If we add a WBS summary activity for WBS code W, our WBS activity will summarize A1, A2, A3, and our LOE activity. The WBS activity thus starts at time 0 (the earliest start of any of the activities it summarizes) and finishes at time 20 (the latest finish of any of the activities it summarizes). In this case PSOP would incorrectly schedule the LOE activity to have the same start and finish dates as the WBS activity that summarizes it. The LOE activity would thus finish at time 20 instead of finishing at time 15. This is a known bug that will be fixed in a future version. Back to FAQ
