Question
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?
- A. External
- B. Internal
- C. Mandatory Correct
- D. Discretionary
Explanation
A mandatory (hard) dependency is inherent in the nature of the work: software cannot be installed on a desktop that has not been installed and powered on. A discretionary dependency is a preferred sequence the team chooses and could change. Internal and external describe whether the dependency lies inside or outside the project's control, and the question is about the logical necessity of the sequence, which makes it mandatory.
