Figure 9: Requesting additional funds
After the execution has begun, the agent working on the task might realize that he requires more resources than allocated or that he produces some by products not anticipated. In such cases dialogs like the one in figure 9 provide a simple way to request more resources or provide notification about additional product created. The opposite case is also possible. A user might not require all resources or inputs assigned to his task. This is usually not a critical as missing resources, but allows for resource-reallocation and schedule-optimization on the fly. Therefore a number of dialogs exist that allow a user to report such cases. Further dialogs allow to protest against a scheduled duration or even cancel work on task.
What all these dialogs do is basically find out which person created the schedule in the first place and forward the complaint to him. The PM will not make any evaluation on these messages and will not perform schedule-changes. It is the responsibility of the message recipient, the agent that generated the schedule, the change that schedule according to the complaint.
