2BaysideFinancial–ProjectPlanning
At Bayside Financial, where you work as a project manager, you have been asked to conduct user training sessions for a new information system. You must develop a specific schedule for the tasks (the estimated task duration for each is shown in parentheses):
First, confirm arrangements for the training facility you plan to use (3 days). After you have confirmed the training facility, two tasks can begin at the same time: you need to send an e-
mail message to all department managers announcing the training sessions (1 day) and you can develop the
training material (5 days). As soon as the training material is complete, you can work on two tasks at once: arrange to have copies of

Draw a context diagram for the order system.
What are the data flow and process combinations that must be avoided when creating a DFD?
