The project planning board is a graphical tool that allows you to plan and monitor projects in a Gantt chart view. You can use the project planning board to display capacity requirements and maintenance orders that are related to project activities. You can also display other objects such as WBS elements, networks, activities, milestones, production orders, sales orders, purchase orders, and so on.
