The main advantage of working with a Gantt Chart is that you get to plan, schedule, and execute your projects on just one chart. You get to keep everyone on the same page from product managers, program managers, business analyst, developers etc. This helps you to manage the whole project in an efficient manner by taking note of the projection timeline. This is a tool that clearly outlines tasks and to which teams they have been assigned to.
This is a chart that is mostly used in project management visually representing projection timelines for the project and the tasks.
