A level of effort activity’s duration is dependent on its predecessor and/or successor activities. Level of effort activities cannot have constraints assigned to them. Level of effort activities are not included when leveling resources.
Use level of effort activities for on-going tasks that depend on other activities. For example, you could assign level of effort activities for clerical work, a security guard, or even some aspects of project management.
A level of effort activity is similar to but different from a hammock activity.
- A level of effort activity uses its assigned calendar to summarize its dates. Hammocks are not scheduled using their own calendar.
- Any type of relationship can be assigned to a level of effort activity. Only a start-to-start and finish-to-finish relationship can be assigned to a hammock activity.
- A level of effort activity's duration is calculated from the earliest early start of its predecessors/successors (linked to the start end of the level of effort activity) to the latest early finish of its predecessors/successors (linked to the finish end of the level of effort activity).
A hammock activity’s duration is calculated from the earliest early start of its predecessors to the latest early finish of its successor activities.
