Final answer:
A Gantt chart does not explicitly show precedence requirements for a project's activities; this is instead depicted in Precedence Diagrams or network diagrams.
Step-by-step explanation:
The statement that a Gantt chart explicitly shows the precedence requirements for a project’s constituent activities is False. A Gantt chart is a project management tool that shows the timeline of a project, illustrating the start and finish dates of the various required elements or parts of a project. While it is excellent for tracking project schedules and showing what work is scheduled to be done on a certain day, it does not by itself show dependencies or precedence relationships between tasks. Instead, precedence requirements are more commonly shown in a Precedence Diagram Method (PDM) or a network diagram, where the sequence and interdependencies of tasks are clearly illustrated.
