Tom is the project manager of the GHQ Project for his organization and he is working on
recovering the project schedule. As Tom examines his schedule, he is especially aware of project
activities with hard logic. What is hard logic?

A.
Hard logic describes activities that can be completed in any order but are positioned with finish-to-start relationships.

B.
Hard logic describes activities that have external constraints, such as a vendor.

C.
Hard logic describes activities that must be completed in a particular order unless additional
resources with comparable skill sets can be added to the project.

D.
Hard logic describes activities that must be completed in a particular order.

Explanation:
Hard logic, also known as mandatory dependencies, describes activities that must be completed in
a particular order. Hard logic is a binding connection between activities. It is also known as
mandatory dependency or hard dependency. Hard logic requires activities to take place in a
specific order according to the nature of work. It is a well-built connection where an activity cannot
start until and unless a previous one is completed. There are also substantial hard logic
connections where soft logic does not usually apply. Several activities rely on hard logic for the
successful completion of the project.
Answer options B, A, and C are incorrect. These are not a valid description of hard logic.
