C. In the diagram for the first-level object a green line is displayed — this is the maximum level of the efforts available. This level is calculated as the total average performance of the employees linked with the objects in the navigation panel which are shown in the diagram as layers.
If the green line is far above the diagram this may mean that information about the projects was not imported/keyed in completely.
If the information is complete and a layer exceeds the green line this means the employees are overloaded; if the diagram is below the green line this means the employees are underrun.
If the diagram is above the green line all along the timeline then the overall workload of the employees exceeds their capabilities.
