the “driving path to project completion.” Unfortunately, this is not the case, as activities A1 (TF=10) and B1 (TF=8) are now included – incorrectly – on the Longest Path. Critical Path by Total Floatįor this simple project, the Critical Path based on Total Float should be identical to the Critical Path based on “Longest Path” – i.e. The corresponding Critical Path, as determined by Total Float (TF=0), is highlighted red on the Gantt Chart. All activities are on the same calendar, and there are no constraints or resources. The side activities must be completed before the final activity G can start. Here is a simple example project comprising a Critical Path of activities A-B-C-D-E-F-G with a side branch of associated activities A1-B1-C1-D1-E1-F1. This can create issues when the project’s Critical Path is defined using the Longest Path option. A hammock activity’s duration is calculated from the earliest early start of its predecessors to the latest early finish of its successor activities.ĭespite the increased flexibility afforded by LOE activities in P6 – and its implied indifference to predecessor or successor relationships – many users continue to use SS-predecessors and FF-successors when establishing LOE dates.

In prior software versions, hammocks were constructed by establishing a group of start-controlling activities as SS predecessors and a separate group of finish-controlling activities as FF successors. They are effectively a replacement for the “hammock” activities that existed in prior versions of Primavera products, including Primavera Project Planner (P3) and SureTrak Project Manager. Level-of-Effort (LOE) activities in Oracle Primavera P6 project scheduling software are useful for summarizing the schedule dates of other (primary) activities. This short entry demonstrates why Level of Effort activities in Oracle Primavera P6 should be constructed using predecessor successor relationships only – especially when designating Critical activities using the Longest Path algorithm.
