As the Beirut Airport Project Gantt Chart suggests, a Gantt chart is a project management tool assisting in the planning and scheduling of projects of all sizes, although they are particularly useful for simplifying complex projects. Project management timelines and tasks are converted into a horizontal bar chart, showing start and end dates, dependencies, scheduling, and deadlines, including how much of the task is completed per stage and who the task owner is. Before you start making the Gantt Chart diagram, you should learn that the underlying concept of a Gantt chart is to map out which tasks can be done in parallel and which need to be done sequentially. The Beirut Airport Gantt Chart shows the details of every flight, boarding time, departure hour, arriving time of certain flights, and more.
