You have created the project network diagram for your project. Management is reviewing the
network diagram and they are curious as to why you have included levels of effort activities as
start-to-start and finish-to-finish successor activities for work that uses particular manufacturing
equipment. You explained that the levels of effort activities are maintained for the equipment. This
relationship and scheduling scenario is also known as what term?

A.
Project management overhead

B.
Hammock activity

C.
Subproject

D.
Finish-to-Start

Explanation:
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.
Answer option D is incorrect. Finish-to-start is the most common relationship between project
activities in the project network diagram.
Answer option A is incorrect. Project management overhead describes the work that supports the
project objectives, but is not linked directly to the project deliverables.
Answer option C is incorrect. 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.
