Suggested Answer: B 🗳️
This is also known as a hammock activity, as the SS and FF relationship hangs off of the activities in the project network diagram. A hammock activity is a schedule or project planning term for grouping of subtasks that "hangs" between two end dates it is fixed to. It groups subtasks that are not related in the hierarchical sense of a Work Breakdown Structure. It also groups subtasks that are not related in a logical sense of a dependency where one subtask must wait for another. A hammock activity usually refers to report information that is time-dependent and lasts from the initial to the latest date of the activities it encompasses. By using a hammock activity, the top management is able to see an overview of the project without being besieged by details.
Incorrect Answers:
A: Project management overhead describes the work that supports the project objectives, but is not linked directly to the project deliverables.
C: A subproject is a discrete set of work that contributes to the project, but branches off the primary project work. A subcontract portion of the project is an example of a subproject.
D: Finish-to-start is the most common relationship between project activities in the project network diagram.
