The start dates for a hammock were defined by its Start-Start predecessors finish dates came from its Finish-Finish successors the same activity could not be included in both groups. Primavera Project Planner (P3) and Primavera SureTrak Project Manager, for example, both included specific hammock activity types that would be specially treated in the schedule calculations. Primavera scheduling tools have long provided explicit activity types for specifying hammock or LOE activities. When first described in hand-drawn activity-on-arrow (AOA) network diagrams, the time-summarizing activity took the shape of a simple curved line slung between two nodes – i.e. * The “hammock” name refers to the simple method of suspending a sleeping net or cloth (i.e. Since hammocks and LOE tasks do not possess any driving logic, they should be excluded from any formal definition of the Critical Path for the project. Hammock and LOE tasks are essentially the same, though minor differences exist in the implementation by different software. Typically, hammock or LOE tasks are used to represent the indirect management and other support activities associated with the primary tasks, and they are often loaded with management and other indirect resources. “Hammock”* and “Level of Effort” (LOE) tasks in project schedules provide two similar approaches to summarizing and reporting the overall time consumed by a collection of other tasks. This entry describes the basis for hammock-type summary tasks and introduces an alternate method (and UpdateHammocks macro) for creating and maintaining such tasks in Microsoft Project (MSP) schedules.
