By starting with a hierarchical representation of tasks and their dependencies (WBS), you can then layer in Gantt chart components such as time, ownership, status, milestones, etc. It depicts what tasks (and subtasks) are to be completed, but it does not show when each task will begin and end. It is often the foundation for creating a solid Gantt chart. This relates to Work Breakdown Structure of WBS, a specific method of breaking down large or complicated goals into manageable objectives.
This can also be useful as a high-level guide for managers as they are tracking project progress.
Understanding a project’s scope and requirements is made easier with Gantt charts because they provide a visual representation of your project at any stage, including task dependencies, priorities, and ownership. Project management with Gantt charts could include anything from resource management plans to planning killer marketing campaigns. A Gantt chart is primarily used to assist the planning and scheduling of projects of all sizes, but they are particularly useful for simplifying complex projects and their KPIs.
