In a Gantt chart, a project is broken down into what?

A Gantt chart is a fundamental project management tool used for scheduling and visualizing project timelines. It is a type of bar chart where the vertical axis lists the project tasks or activities, and the horizontal axis represents time. Each activity is represented by a bar, the position and length of which correspond to the start date, duration, and end date of the activity. This structure provides a clear and immediate overview of the project's breakdown into specific activities and the time periods allocated for their completion, illustrating what needs to be done and when.

A. This describes a Responsibility Assignment Matrix (RAM), such as a RACI chart, which is used to clarify roles and responsibilities.

B. This is the function of a risk register or a risk management plan, which identifies potential risks and outlines mitigation strategies.

D. This relates to a project budget or a cost management plan, which tracks financial allocations and ownership, not the project schedule.

The guide describes bar charts (Gantt charts) as showing "activities...listed on the vertical axis and dates shown on the horizontal axis. The activity durations are shown as horizontal bars placed according to start and finish dates."

3. Kerzner, H. (2017). Project Management: A Systems Approach to Planning, Scheduling, and Controlling (12th ed.). John Wiley & Sons. Chapter 12, "Scheduling," explains that a Gantt chart is a graphical representation that displays "work to be accomplished on the vertical axis and the time to accomplish the work on the horizontal axis" (p. 458).
