A Gantt chart is not a roadmap. The chart is a type of bar diagram that represents a project schedule, showing the start and finish dates of tasks or the entire project. In contrast, a roadmap outlines a strategic plan and high-level goals of a project or product, focusing on the vision, milestones, and long-term objectives. While both are planning tools, a Gantt chart is more detailed and time-specific, whereas a roadmap is broader and more strategic. Project managers often use a Gantt chart to create a roadmap, as it perfectly visualizes all project details and shows a top-level work plan.
