The project team determines that software installation can only begin after the desktops have been installed
and can be powered on. Which of the following dependencies does this represent?
Correct Answer: C
The dependency between software installation and desktop installation is a mandatory dependency. A
mandatory dependency is a type of dependency that is inherent in the nature or logic of the work and cannot be
avoided or changed. It is also known as a hard dependency or a hard logic dependency. A mandatory
dependency means that one task must be completed before another task can start or finish. For example,
software installation can only start after desktop installation is finished5
The dependency between desktop installation and software installation represents a mandatory dependency. A
mandatory dependency is a type of task dependency that is inherent in the nature of the work being performed.
In this case, software installation cannot begin until desktops are installed and powered on, and therefore, the
dependency is mandatory. References: CompTIA Project+ Study Guide, Chapter 3: Project Integration
